Cleanroom Furniture
Precision-Built for Sterile Environments
In a controlled environment, every piece of furniture is a critical extension of your contamination control strategy. Metrolabs cleanroom lab furniture is engineered with a “Zero-Ledge” philosophy — eliminating every dust trap, crevice, and particle accumulation point while providing an ergonomic, high-accuracy platform for pharmaceutical, biotech, and semiconductor research.
Four Furniture Categories — One Integrated Clean Shell
Every Metrolabs cleanroom furniture category is engineered to the same Zero-Ledge, non-shedding, sterilisation-compatible standard — forming a cohesive, hygienic interior infrastructure for your facility.
Engineered for Efficiency — Structural Platforms for High-Stakes Research
Metrolabs workstations are not standard lab benches adapted for cleanrooms — they are purpose-designed structural components built to work with the room’s airflow dynamics, providing a stable, ergonomic, and hygienic platform for critical operations.
Wall-Side Cleanroom Work Tables
Designed to mount flush against modular cleanroom panels, wall-side tables maximise usable floor space while providing a seamless, aseptic interface between the worksurface and the wall. The table frame is welded to a continuous backing plate that seals against the panel surface — eliminating the gap between table and wall that accumulates dust, moisture, and microbial growth in standard installations. The worksurface is available in SS 304 solid, SS 316L solid, or SS 316L perforated — the perforated option (25mm circular perforations on a 45mm pitch) allows vertical laminar airflow from the ceiling HEPA to pass through the worksurface and continue to the floor-level return air risers unimpeded, maintaining the unidirectional piston effect in Grade A critical zones throughout the table area.
Island Cleanroom Work Tables
Central island workstations provide 360° access for multiple researchers working simultaneously — eliminating the wall-access constraint of wall-side tables in rooms where multiple personnel must work around a shared central work area. Island tables are the standard configuration for weighing rooms, sample preparation suites, and central analytical zones where the operator must access the table from multiple sides. The structural frame is a fully welded SS 304 or SS 316L tubular construction with adjustable levelling feet — vibration-resistant floor contact pads in stainless steel with neoprene inserts that prevent metallic vibration transmission to sensitive analytical instruments. Perforated worksurfaces are standard for Grade B and C island tables in pharmaceutical cleanrooms — maintaining unidirectional airflow through the table plane. Service pendants (gas, power, vacuum) are available as overhead integrated fittings rather than routing through the table structure, to maintain the cleanable surface standard at the worksurface level.
L-Shape Cleanroom Work Tables
L-shape workstations are optimised for corner placements — the most space-inefficient location in a rectangular cleanroom — converting what is typically dead floor area into a high-efficiency, expansive worksurface without disrupting the room’s traffic flow or airflow pattern. The L-configuration provides two contiguous worksurface sections meeting at a 90° inside corner, allowing a single operator to conduct parallel tasks (e.g., weighing at one arm while recording at the other) without moving position — minimising body movement and the associated particle generation that each movement creates. The inside corner of the L is designed with an S-bend radius that avoids the right-angle corner recesses of standard L-benches — maintaining the Zero-Ledge principle at the most particle-trapping location of the configuration. Available with perforated or solid worksurfaces and matching backsplash in the same material and finish as the wall panel system.
Secure & Sterile Containment — Non-Shedding, Non-Porous, Non-Particle-Generating
Storage in a cleanroom cannot be an afterthought. Every storage unit is a potential particle source — from shedding surfaces, sharp edges, crevices that accumulate contamination, and horizontal tops where items are illegally stored. Metrolabs storage is engineered to eliminate every one of these risks.
Stainless Steel Storage Cabinets
Fully welded SS 304 or SS 316L cabinets with flush-mounted recessed pull handles (no protruding handles that create particle ledges or cleaning obstacles), continuous coved internal corners (R10 minimum), smooth non-porous internal shelves, and door seals that maintain a positive pressure interior preventing ambient dust from infiltrating stored sterile supplies. Sloped tops at 30° prevent horizontal storage of items on top of the unit — a critical GMP compliance feature since items stored on top of cleanroom cabinets are outside the defined laminar flow zone and become a contamination risk. Available with vision panels (double-glazed borosilicate) for contents identification without door opening, and with integrated lock for controlled substance storage.
Cleanroom Cupboards
Cleanroom cupboards provide enclosed, organised storage for PPE, consumables, documentation, and equipment that must be accessible at the point of use within the cleanroom. Designed with sloped tops as standard to enforce GMP compliance regarding above-cupboard storage. Internal shelves are adjustable, perforated SS panels — the perforation pattern prevents standing water on shelves and allows vertical air circulation to prevent stagnant air pockets developing within the closed cupboard. Hinges are concealed within the door frame thickness — no exposed hinge pins that create cleaning obstacles or particle traps. Magnetic or SS lever handles flush with the door face. Removable internal shelf units for complete interior decontamination without structural disassembly.
Chemical Storage Cabinets
Purpose-engineered for the storage of volatile, flammable, or corrosive reagents within the cleanroom — an environment where standard flammable chemical storage cabinets are frequently non-compliant because they introduce particle-shedding materials (painted steel, plastic vents) into a particle-controlled space. Metrolabs chemical storage cabinets are fabricated from SS 316L throughout — the most corrosion-resistant option — with an integrated full-perimeter sump tray that contains any liquid spills, preventing contamination of the cleanroom floor and drain system. Ventilation ports (with integral flame arrestors for flammable solvents) connect to the room’s dedicated solvent extraction system, preventing build-up of flammable vapours inside the cabinet. Self-closing door mechanisms meet COSHH and OSHA storage requirements for flammable reagents.
Material Storage Racks
Open-frame SS 304 storage racks with fully perforated shelving — designed to allow vertical laminar airflow to pass through the shelf plane without obstruction, preventing the “dead air” pockets that solid shelving creates directly below each shelf level. Dead air pockets within storage racks are a common particle monitoring excursion source — the stagnant air allows particles to settle and accumulate on stored materials and shelf surfaces, creating a localised contamination source even in an otherwise compliant cleanroom. Perforated shelving eliminates this by maintaining continuous downward airflow through every tier of the rack. Frame construction is fully TIG-welded SS 304 tube — no threaded connectors or slot-and-clip assemblies that create crevices and shed metallic particles from vibration-induced loosening. Available with castors for mobility or with levelling feet for fixed installation.
Aseptic Hygiene & Support — Total Wipe-Down Accessibility
Moisture and waste management are high-risk factors in sterile zones. Metrolabs utility units are designed for complete “wipe-down” accessibility — every surface reachable, every corner coved, every connection removable for deep decontamination.
Cleanroom Sink Units
Deep-drawn, coved bowl sinks with a continuous R10 radius at every internal corner — eliminating the recessed corners where microbial biofilms colonise in standard cleanroom sinks. The bowl is formed from a single pressed sheet of SS 316L in a single TIG-welded weld line at the bowl-to-counter interface — no additional welds or joints within the bowl that create crevices. The counter surface is sloped — a minimum 3° fall toward the bowl — ensuring that any water on the counter surface drains passively into the bowl rather than pooling on the flat surface and creating a standing-water microbial risk. Integrated overflow at the rear of the bowl with a removable overflow cover for inspection and cleaning. Undersink space is fully enclosed with a removable door panel for access to pipework during maintenance.
Hands-Free Foot Operated Sink Units
Mechanical foot pedal operation eliminates all hand contact with the tap/valve mechanism — maintaining surgical-level hand hygiene protocols from the moment the operator approaches the sink to the completion of handwashing. The foot pedal mechanism is a fully stainless steel lever-and-cable assembly — no pneumatic or electronic components that require maintenance or can fail in a high-humidity sink environment. The cable actuates a direct-action stainless steel water valve — the valve closes immediately when foot pressure is released, preventing the overwater or drip that continually wet sink areas experience with conventional taps. Sensor taps (infrared-triggered) are also available for sink units where foot pedal installation is constrained by the floor construction. The entire sink unit — body, bowl, counter, pedal mechanism, and exposed pipework — is SS 316L throughout for maximum corrosion resistance in the high-humidity, high-cleaning-agent sink environment.
Sanitation Wash Stations
All-in-one scrub-in and gowning support hubs typically installed at the airlock entry to the cleanroom — providing a single, organised unit that combines hand-washing, hand drying, glove dispensing, and gowning support in one accessible station. The wash station incorporates a foot-operated SS 316L sink bowl, a HEPA-filtered hand dryer (delivering Grade D or better filtered air to prevent recontamination of washed hands during drying), and a series of integrated dispensing pockets for gloves, gowning consumables, and PPE items. The unit body is a fully welded SS 316L enclosure with a flat-section door that provides access to the supply shelf and dispenser refill points from outside the cleanroom — avoiding the need for cleanroom personnel to receive supplies directly. All surfaces are coved at every junction and designed for complete IPA wipe-down.
Utility / Support Tables
Versatile, stationary SS 304 support tables for secondary equipment housing, sample preparation, weighing, and auxiliary instrument positioning within Grade C/D cleanroom zones. Utility tables are designed with a minimal open frame structure — maximising the visible floor area under the table to facilitate effective floor cleaning and to make visible any items that have fallen or been placed under the table contrary to GMP requirements. The worksurface is available as SS 304 solid, SS 316L solid, or perforated — the choice determined by the ISO class of the room and whether the table is positioned within a laminar flow zone where perforated surface is required. Undershelf optional — when supplied, the undershelf is perforated for the same airflow-preservation reason as the main shelf. Adjustable levelling feet standard. Available in custom dimensions for non-standard equipment housing requirements.
High-Accuracy Logistics — Vibration-Free, Non-Marking, Non-Shedding
Movement within and between cleanroom zones must be fluid, controlled, and non-contaminating. Metrolabs mobility solutions use medical-grade, non-marking casters and vibration-dampening mounts to ensure that material transit does not generate particles, damage sensitive instruments, or disturb the cleanroom pressure cascade.
Cleanroom SS Trolleys
Multi-tier perforated SS 304 transport trolleys built with reinforced welded frames and swivel/braked medical-grade non-marking polyurethane casters for the movement of supplies, consumables, and semi-finished products through different ISO-class zones. The fully perforated tier shelves — standard 25mm holes on 45mm pitch — allow air to circulate freely through the loaded trolley as it moves through the cleanroom, preventing the trolley from acting as a “sail” that disrupts the laminar airflow field as it is pushed through the room. All welds are TIG-finished and electropolished internally and externally — creating a smooth surface that can be fully IPA-wiped before zone transit to prevent cross-contamination between ISO-class areas. Handle bars are SS 304 tube with a continuous coved weld at the frame junction — no bolted or screwed attachments that shed particles from vibration.
Material Transfer Carts
Heavy-duty SS 316L material transfer carts designed for the safe transit of bulk raw materials, packaging components, or finished products to pass-through windows, material airlocks, and inter-zone transfer points. The cart deck is a solid SS 316L sheet with full perimeter upstand (50mm minimum) to prevent items from sliding off during movement, and the deck surface is electropolished to allow complete IPA wipe-down before and after each transit. Heavy-duty swivel casters (125mm diameter, non-marking polyurethane, 200kg rated per caster) with individual locking mechanisms allow the cart to be parked at a pass-through window, weighed, or loaded without movement. The cart frame incorporates a continuous lower shelf of perforated SS 316L for secondary load capacity. Available in push-handle and tow-bar configurations for different cleanroom corridor layouts and transit distances.
Instrument Trolleys
Specialist instrument transport trolleys featuring anti-vibration isolation mounts to protect high-accuracy analytical instruments — balances, spectrophotometers, viscometers, particle counters — during movement between lab modules or between the cleanroom and an adjacent equipment room. The platform on which the instrument sits is mounted on four anti-vibration isolators — typically natural rubber or neoprene compression mounts rated for the instrument’s mass — that decouple the instrument from the trolley frame and prevent floor vibrations, trolley-frame resonances, and caster impacts from being transmitted to the instrument’s sensitive measuring components. The platform and frame are fully SS 316L for maximum chemical resistance in environments where instrument surfaces are regularly wiped with aggressive cleaning agents. Individual swivel-lock casters allow the trolley to be locked stationary during instrument operation.
Material & Construction Standards
Every Metrolabs cleanroom furniture unit is specified, fabricated, and finished to the following technical standards:
| Feature | Metrolabs Standard | GMP Benefit |
|---|---|---|
| Primary Material | SS 316L (Surgical Grade) | Maximum corrosion resistance — VHP & aggressive agent safe |
| General Material✓ Std | SS 304 (Industrial Grade) | Cost-effective — IPA / QAC / PAA compatible |

High-Accuracy Fabrication — Every Unit Degreased, Passivated & VHP-Tested
Metrolabs does not adapt commercial stainless furniture for cleanroom use — we design and fabricate cleanroom-specific solutions from the ground up, for the pharmaceutical, biotech, and semiconductor sectors.
Zero-Ledge Philosophy — Every Surface
Every surface on every Metrolabs cleanroom furniture unit is designed and verified to have zero horizontal ledges, recesses, or steps where particles can accumulate. Sloped tops on storage units, coved corners throughout, flush-mounted handles and hardware, and continuous welds at all frame-to-surface junctions eliminate the particle traps that non-cleanroom-specific furniture invariably creates.
Fully TIG Welded — No Bolt-and-Bracket Assembly
Bolt-and-bracket assembly creates multiple contamination points: the bolt thread accumulates particles, the bracket interface creates an inaccessible crevice, and metallic vibration from cleaning activities can loosen connections and shed metallic particles. Every Metrolabs cleanroom furniture unit is fully TIG welded — the only joint type compatible with the cleanroom requirement for non-shedding, crevice-free surfaces throughout.
Electropolished to Ra <0.5μm — Biofilm Inhibition
Electropolishing removes the microscopic surface asperities (peaks and valleys at the Ra micron scale) that provide physical anchorage for biofilm formation. At Ra <0.5μm, the surface is sufficiently smooth that bacterial adhesion is dramatically reduced, cleaning agents can remove biofilm precursors in a single wipe, and disinfection validation is simplified — each of which directly reduces the microbiological risk at the work surface in pharmaceutical and food cleanrooms.
Perforated Worksurfaces — Preserving Laminar Flow
In Grade A and B zones, any solid surface interrupts the vertical laminar airflow — creating a stagnant zone immediately above the solid surface where particles accumulate rather than being swept to the return air risers. Metrolabs perforated worksurfaces (standard ∅25mm holes on 45mm pitch) allow the laminar piston to pass through the work plane uninterrupted — the critical zone above the product or sample remains within the laminar flow column, maintaining ISO Class 5 air quality at the point of use.
VHP Compatible — Survives 500+ Decontamination Cycles
Every Metrolabs SS 316L furniture unit is validated for full-cycle VHP (Vaporized Hydrogen Peroxide) exposure — including the high-concentration VHP used in BSL-3 and aseptic pharmaceutical facility decontamination programmes. The combination of SS 316L material, citric acid passivation, and electropolished surface maintains dimensional stability, weld integrity, and surface finish after 500+ VHP cycles — providing the full service life of the cleanroom facility without structural degradation.
Audit-Ready Documentation — From Day One
Every Metrolabs cleanroom furniture unit is supplied with a material test certificate (MTC) confirming the SS 316L or SS 304 grade, heat number, and mechanical properties; a passivation certificate (ASTM A967 or equivalent) confirming post-fabrication treatment; and a declaration of conformity to ISO 14644-4 cleanroom furniture design requirements — the complete documentation package required for GMP facility validation and regulatory audit evidence.
Technical Insight — Perforated Worksurfaces for Grade A and B Zones
For Grade A and B cleanroom zones, Metrolabs strongly recommends Perforated Worksurfaces on all workstations, trolleys, and storage racks positioned within the laminar flow zone. A solid surface interrupts the unidirectional downward airflow — creating a stagnant pocket directly above the surface where particles generated by the operation accumulate rather than being swept downward to the return air risers. A perforated surface (∅25mm holes on 45mm pitch provides approximately 30% open area) allows the laminar piston to continue through the work plane, ensuring that the air directly above your samples, products, or open containers maintains Grade A (<1 particle ≥0.5μm per m³) air quality throughout the critical operation. This structural choice is the single most impactful contamination control decision for laboratory workstation specification in pharmaceutical Grade A cleanrooms.
