View Microbiology Equip →Every Category — Engineered for GMP, ISO & Pharmaceutical Standards
Each Metrolabs cleanroom solution category covers the complete product range required for full GMP compliance — from the sub-structure to the air-handling to the primary containment equipment:
The civil and structural phase of cleanroom construction establishes the substrate on which every subsequent system — partition panels, furniture, equipment — is installed. Metrolabs cleanroom flooring systems are engineered for pharmaceutical GMP compliance: seamless (no grout joints, cracks, or expansion gaps where bacteria accumulate), anti-bacterial (biocide-incorporated epoxy formulations that resist microbial colonisation on the floor surface), anti-static (where electrostatic discharge is a risk — electronics and semiconductor environments), and chemical-resistant (withstanding the full range of pharmaceutical cleaning agents, disinfectants, VHP, and reagent spills at working concentrations). The coving skirting at the floor-to-wall junction is the GMP requirement most often missed in non-specialist cleanroom construction — without a continuous coved transition at the floor perimeter, the right-angle junction becomes a particle, moisture, and biofilm accumulation point that resists routine cleaning.
Explore Civil Works →🔌 ISO Substrate
Every Metrolabs cleanroom floor system is designed as the ISO-compliant substrate for the modular panel system installed above it — dimensional tolerances, levelness, and structural load capacity are specified to the panel manufacturer’s requirements.
The wall and partition system defines the physical cleanroom boundary — the structural and thermal barrier that enables the HVAC system to establish and maintain the ISO class pressure cascade. Metrolabs supplies PUF panels (standard pharmaceutical), sandwich panels (fire-rated pharmaceutical and hospital applications), and full modular cleanroom panel systems (demountable, reconfigurable, compatible with all Metrolabs pass box and equipment mounting systems). All panel systems are supplied with compatible corner coving profiles for the wall-to-wall vertical junctions — ensuring GMP coved corners are maintained at every internal vertical junction throughout the cleanroom, not just at the floor-to-wall junction. Panel systems are supplied pre-cut to the facility dimensions, with all cut edges sealed, and with the cleanroom-grade surface finish (pre-painted GI, SS cladding, or HPL facing) specified for the ISO class and cleaning protocol of each room in the facility.
Explore Wall Systems →Every door and window in a cleanroom is a potential pressure cascade breach point — the moment a door opens, the pressure differential between the two rooms connected by the doorway is exposed to an air pathway, and particles and micro-organisms can transit from the lower-pressure room to the higher-pressure room in the induced airflow. Metrolabs hermetically sealed, air-tight, and interlocking door systems are engineered to minimise this transit risk through high-quality sealing (medical-grade silicone gaskets at the full door perimeter, compressing to an airtight seal at all four edges of the door frame when the door is closed and latched), fast-closing door closers (limiting the duration of the open-door period), and interlocking systems (for airlocks and gowning rooms that require both doors to not be simultaneously open). View panels (double-glazed, flush-mounted, zero-ledge) provide inter-room visibility without requiring a door opening event.
Explore Doors & Windows →The HVAC and air handling system is the active engineering heart of the cleanroom — it establishes and maintains the ISO class classification (particle count), the temperature and relative humidity, and the pressure cascade between rooms of different ISO class that is the primary contamination control mechanism for the facility. Metrolabs supplies the complete HVAC system for pharmaceutical cleanrooms: Air Handling Units (AHU) with primary and secondary filtration stages, GI ductwork to distribute conditioned air to the cleanroom zones, H14 HEPA terminal filter units at the cleanroom ceiling supply points, return air risers and distribution plenums, pre-filters and fine filters for the intermediate filtration stages, differential pressure sensors at every zone boundary for continuous pressure cascade monitoring, and temperature and humidity controllers for environmental monitoring compliance with GMP requirements.
Explore HVAC Systems →Cleanroom furniture must meet a set of engineering requirements that standard office or laboratory furniture does not: every horizontal surface must be a zero-ledge surface (no recessed top frame, no raised edge, no hidden ledge underneath the work surface top that collects dust between cleaning cycles); every corner must be coved (no right-angle internal junction); all materials must be resistant to the full range of pharmaceutical cleaning agents, disinfectants, and VHP at working concentrations; and all structural components must be non-particulating (no paint that chips or peels, no fabric, no wood). Metrolabs cleanroom furniture is fabricated from SS 304 (standard) or SS 316L (optional) throughout — workstations, storage cabinets, sink units, and trolleys — with the zero-ledge philosophy applied at every horizontal surface. Workstations are available in wall-side, island (centre), and L-shape configurations to match the cleanroom floor plan. Storage cabinets cover stainless steel general storage, cleanroom cupboards, chemical storage cabinets, and material storage racks. Utility items include cleanroom sink units, hands-free foot-operated sinks for gowning areas, and sanitation wash stations. Mobility items include SS 316L trolleys, material transfer carts, and instrument trolleys.
Explore Cleanroom Furniture →👤 GMP Gowning Compliance
Hands-free wash stations are the GMP requirement at every gowning room entry point — preventing the hand contamination that touch-operated taps create during the gowning process when cleanroom personnel are transitioning from unclean to clean hands.
🔧 Zero-Ledge Wall-Hung
All Metrolabs sanitation units are wall-hung zero-ledge — no floor-mounted pedestal that obstructs floor cleaning, no horizontal ledge that collects water and contamination around the basin perimeter.
The sanitation and hygiene system at the gowning room entry point is the first physical contamination control barrier that GMP personnel encounter at the start of every shift — and it is the point where the most common contamination event in pharmaceutical cleanrooms occurs: the operator touches the faucet handle with a contaminated hand to turn on the water, washes their hands, and then touches the same contaminated faucet handle again to turn off the water. The mechanical foot-pedal and knee-operated wash basins supplied by Metrolabs eliminate this event entirely — the water is controlled by foot pressure or knee pressure, and the operator’s hands never contact any surface between the start and end of the handwashing operation. The spring-loaded foot pedal mechanism is rated for 500,000 complete open-close cycles — the full operational life of the wash station in a high-throughput pharmaceutical facility without spring replacement — and the mechanical system requires no electrical supply, eliminating the electrical failure mode that affects electronic sensor-operated faucets.
Explore Sanitation Systems →Air Control Systems are the engineering solution to the contamination risk that every material transfer event creates — the moment a door between two ISO-classified zones is opened to allow material to transit, the pressure differential between the zones is exposed to a direct air pathway, and micro-organisms and particles can travel from the lower-pressure zone to the higher-pressure zone in the induced airflow. Pass boxes and pass-through cabinets eliminate this risk by providing a sequential-access-only pathway: only one side of the pass box can be open at any time, ensuring the two zones are never simultaneously exposed to a shared air channel. The Dynamic Pass Box adds a further layer of protection by generating its own Grade A (ISO Class 5) environment inside the chamber using HEPA filtration — actively decontaminating the surface of every item transferred before the inner (clean zone) door is opened. The Static Pass Box relies on the room pressure differential and hermetic door sealing for contamination control. The Pass-Through Cabinet extends the same principle to industrial logistics scale for trolley, drum, and large equipment transfer.
Explore Air Control →🔌 Class-Crossing vs Same-Class
Use a Dynamic Pass Box when materials cross from a lower to a higher ISO class — active HEPA surface decontamination required. Use a Static Pass Box for same-class transfers where pressure integrity is the contamination control requirement.
☢ BSC vs LAF — The Critical Choice
The BSC Class II protects the operator, the sample, and the environment simultaneously — use for all biological agents. The LAF protects only the sample — never use for infectious or hazardous agents. Wrong choice creates personnel exposure risk.
🔥 VHP Compatibility
All Metrolabs BSC and LAF components — gaskets, sash seals, viewing panels, drain seals — are VHP-compatible at 1000 ppm. Equipment can be processed in the same room-wide VHP cycle as the cleanroom without disassembly.
The microbiology room is the controlled biological work environment where the most stringent contamination and biosafety requirements of the pharmaceutical and research facility converge — the room must be an ISO-classified cleanroom to prevent ambient particulate contamination of biological samples, and the primary containment equipment within the room must provide the additional biological containment that the room itself cannot — protecting the operator from aerosols generated by the biological work, and protecting the room environment from any biological agent that the work generates. The Biosafety Cabinet Class II (EN 12469 / NSF 49) provides all three layers of protection simultaneously: the inward air curtain at the front sash opening protects the operator, the HEPA-filtered downflow creates a Grade A work surface that protects the sample, and the HEPA-filtered exhaust protects the room environment. The Laminar Air Flow unit provides Grade A sample protection for non-hazardous biological and chemical work — PCR setup, media preparation, tissue culture accessory preparation, and precision weighing — without the containment features of the BSC.

Single Specialist Source for the Complete Cleanroom Ecosystem
Metrolabs is the only specialist manufacturer in South India providing all eight cleanroom solution categories from a single source — eliminating the coordination failures between separate civil, panel, HVAC, furniture, and equipment contractors that cause the most common cleanroom qualification failures:
Single Source — Zero Coordination Gap Between Systems
When the civil contractor, panel contractor, HVAC contractor, furniture contractor, and equipment contractor are all different companies, the coordination failures between them — dimensional mismatches, incompatible junction details, conflicting installation sequences — are the primary cause of cleanroom qualification failures and rework costs. Metrolabs provides all eight categories from a single facility in Chennai, with a single project manager who coordinates all categories across the same timeline and to the same dimensional specification.
Factory-Validated IQ Documentation at Handover
Every Metrolabs cleanroom system component is factory-validated before dispatch: pass boxes and LAF units with PAO/DOP HEPA integrity tests, BSC units with inflow and downflow velocity measurements and smoke tests, pass-through cabinets with 2000 kg floor load tests and EM interlock function tests. The factory validation records are compiled into a structured IQ documentation package at handover — formatted for direct inclusion in the facility’s GMP/ISO qualification submission without re-formatting by the facility’s quality team.
Zero-Ledge Philosophy — Applied to Every Horizontal Surface
The Zero-Ledge design philosophy is Metrolabs’ core design principle: every horizontal surface — workstation top, pass box door frame, sink drainer, HVAC plenum top, LAF work surface, BSC sash frame, panel-to-floor junction — is designed to have no external dust-collecting ledge. This eliminates the most common contamination audit finding in pharmaceutical cleanrooms — the dust-laden horizontal surfaces that accumulate between cleaning cycles and create particle re-suspension events during activity.
