Labconco Purifier 3873021 Horizontal Clean Bench Overview

The Labconco Purifier 3873021 is designed to protect samples and processes from airborne particulate contamination by continuously sweeping the work area with HEPA-filtered horizontal laminar airflow.

Room air enters the clean bench through disposable prefilters located above the cabinet. These prefilters capture larger airborne particles before air reaches the primary HEPA filter. The air then passes through a 99.99% efficient HEPA filter and flows horizontally across the work area toward the operator.

This unidirectional airflow helps minimize turbulence and continuously displaces contaminants away from sensitive samples, providing ISO Class 5 conditions within the work zone when the unit is properly installed, maintained, and operated.

The 3873021 is one of the larger Purifier configurations. Its approximately 73-inch interior width and 26-inch working depth provide considerably more usable space than a standard 3- or 4-foot clean bench. This makes it particularly useful for laboratories working with multiple culture vessels, preparation trays, electronics assemblies, medical devices, or other larger workflows.

An integrated UV lamp provides an additional option for work-area decontamination when the bench is not occupied. UV treatment is supplemental and should not replace established cleaning and disinfection procedures.

Labconco Purifier 3873021 Key Specifications

Specifications compiled from Labconco manufacturer literature and American Instrument Exchange product information.

Common Applications

The Labconco Purifier 3873021 is well suited for plant tissue culture, non-hazardous cell and tissue culture preparation, media plate preparation, sterile media handling, pharmaceutical preparation, electronics inspection, optical component assembly, medical-device assembly, precision component work, and other procedures requiring a particulate-controlled work environment.

The 6-foot width makes this model especially useful when several vessels or components must be handled simultaneously or when larger equipment must be positioned inside the clean work area.

Ideal Laboratory Environments

The Labconco 3873021 is an excellent choice for biotechnology laboratories, pharmaceutical facilities, university research laboratories, plant biology laboratories, medical-device manufacturers, electronics laboratories, optical laboratories, quality-control departments, clinical research environments, and industrial cleanroom facilities.

It can also be valuable in shared laboratory environments where a large ISO Class 5 workspace is needed for several preparation steps or for larger assemblies that cannot be accommodated comfortably inside a smaller clean bench.

Horizontal Laminar Airflow & ISO Class 5 Performance

The Purifier 3873021 uses horizontal laminar airflow to protect the work product from airborne contamination.

HEPA-filtered air enters from the rear of the work zone and travels horizontally across the work surface toward the operator. Because the air moves in a uniform direction with minimal turbulence, airborne particles introduced into the work zone are continually swept away from critical materials.

Labconco designed the Purifier Horizontal Clean Bench to provide ISO Class 5 conditions, formerly referred to as Class 100 under Federal Standard 209E.

This airflow design is especially appropriate for contamination-sensitive procedures where the sample requires protection but the material being handled does not present a hazard to the operator.

Double-Gasket HEPA Filter Protection

A distinctive feature of the Labconco Purifier Horizontal Clean Bench is its double-gasket HEPA filter seal.

The primary gasket seals the upstream side of the HEPA filter to prevent unfiltered air from bypassing the filter and entering the work zone. A secondary gasket seals the downstream side of the filter frame.

The space between these two seals is maintained under negative pressure. If leakage occurs at the primary gasket, escaping air is drawn back into the filtration system rather than entering the clean work area.

This design provides an additional level of protection for valuable contamination-sensitive laboratory work.

New HEPA Filter Included

This refurbished Labconco Purifier 3873021 from American Instrument Exchange includes a new HEPA filter.

A new filter eliminates uncertainty regarding previous filter loading and service history while providing a fresh filtration system for the new laboratory installation.

The HEPA filter is rated at 99.99% efficiency for particles 0.3 micron in diameter, creating the particulate-controlled airflow required for ISO Class 5 operation.

Disposable prefilters upstream of the HEPA filter capture larger debris and help extend the useful life of the primary filter. Routine prefilter inspection and replacement can therefore reduce long-term HEPA filter loading and operating costs.

UV Germicidal Lamp

Catalog number 3873021 includes a germicidal UV lamp, distinguishing it from otherwise similar Purifier configurations without UV capability.

The ultraviolet lamp can be used to supplement established work-area decontamination procedures between operating periods.

UV exposure should only be used when personnel are protected from direct ultraviolet radiation and according to applicable laboratory procedures. The UV lamp does not replace routine cleaning and disinfection of the work surface and interior.

Product Protection vs. Personnel Protection

A critical distinction when selecting this equipment is that the Labconco Purifier 3873021 is a clean bench—not a biosafety cabinet.

A horizontal clean bench is designed to protect the product or process from particulate contamination. HEPA-filtered air travels from the back of the cabinet across the work area and then exits toward the operator.

Because air from the work zone moves toward the user, the clean bench does not provide personnel protection or environmental containment.

The Purifier 3873021 should therefore not be used with infectious agents, biohazardous materials, toxins, radionuclides, hazardous chemicals, volatile solvents, or other substances requiring containment.

Applications involving biological hazards generally require an appropriate Class II biosafety cabinet, while procedures involving hazardous chemical vapors may require a chemical fume hood or another suitable containment device.

Clean Bench vs. Biosafety Cabinet

Although clean benches and biosafety cabinets may look similar, their airflow systems serve very different purposes.

A horizontal clean bench protects the sample only. HEPA-filtered air flows across the work surface and toward the operator.

A Class II biosafety cabinet is designed to protect the sample, personnel, and surrounding laboratory through controlled inward airflow, HEPA-filtered downflow, and filtered or exhausted discharge air.

Choosing between these systems should be based on whether the application requires product protection alone or biological containment as well.

Clean Bench vs. Chemical Fume Hood

A clean bench should also not be confused with a chemical fume hood.

A chemical fume hood protects personnel from hazardous vapors by drawing room air into the hood and exhausting contaminated air away from the laboratory.

The Labconco Purifier instead directs clean HEPA-filtered air outward toward the operator. Using volatile or toxic chemicals inside a horizontal clean bench could therefore increase operator exposure.

The 3873021 should only be used for non-hazardous procedures compatible with horizontal laminar airflow.

Large 6-Foot, 26-Inch-Deep Work Area

One of the biggest advantages of catalog number 3873021 is its large workspace.

The cabinet provides approximately:

• 73 inches of interior width

• 26 inches of working depth

• Approximately 30.5 inches of interior work-area height

This larger footprint provides ample room for multiple vessels, preparation trays, instruments, culture containers, medical devices, electronics assemblies, or other contamination-sensitive work.

The 26-inch work depth is particularly noteworthy because Labconco also produced shallower 21-inch versions of the Purifier bench. The deeper configuration gives users additional front-to-back space for larger procedures and equipment.

Certification Readiness & AIE Laboratory Services

Clean benches should be evaluated after installation or relocation to verify that airflow and filter performance meet the requirements of the laboratory and application.

For customers throughout Greater Boston and New England, AIE Laboratory Services can provide clean-air equipment testing, HEPA filter evaluation, airflow testing, repair, preventive maintenance, and related laboratory equipment services.

Because the Labconco Purifier is a clean bench rather than a biological containment cabinet, certification requirements differ from those applied to Class II biosafety cabinets. Laboratories should follow their institutional procedures and applicable standards for their specific application.

Shipping & Installation Considerations

The Labconco Purifier 3873021 is a large 6-foot clean bench and normally ships by freight.

The cabinet measures approximately 75" W × 39" D × 48.4" H, so buyers should verify laboratory doorway dimensions, elevator access, bench or stand capacity, and final placement before delivery.

The system operates on 115 VAC, 60 Hz power and should be installed on a stable laboratory bench or compatible support stand.

No external exhaust ductwork is required because the clean bench draws room air through its filtration system and discharges HEPA-filtered air through the open front.

The clean bench should be positioned away from doors, HVAC diffusers, heavy personnel traffic, and other sources of disruptive room airflow that could interfere with laminar-flow performance.

Related Laboratory Equipment

Laboratories purchasing horizontal clean benches frequently also require biosafety cabinets, CO₂ incubators, laboratory refrigerators, ultra-low temperature freezers, centrifuges, water baths, inverted microscopes, analytical balances, and laboratory water purification systems.

American Instrument Exchange offers refurbished laboratory equipment for biotechnology, pharmaceutical development, tissue culture, medical-device manufacturing, academic research, cleanroom operations, and industrial laboratories.
