Biosafety Cabinet Certification & Maintenance – BSC

SEPS offers comprehensive testing, certification and maintenance of biosafety cabinets. All biological safety cabinets ( BSC’s) are certified to meet NSF-49 F guidelines and manufacture specifications. SEPS technicians follow strict SEPS standard operating procedures (SOP) which remain in compliance with Federal and International Safety Guidelines.

Tests Performed in all certification:

Inflow velocity test Provides personal protection
Down flow velocity test Provides product protection
Hepa filter leak test Provides protection to your working agents and room environment
Smoke visualization test Verifies proper airflow direction
Site installation test & alarm calibration Required on B1 and B2 biosafety cabinets only
Light intensity test Assures sufficient light to prevent operator fatigue
UV light test Assures UV bulb is providing proper sterilization
Electrical safety test Assures that the unit is electrically safe for worker use
Sound test Verifies that the use of the biosafety cabinet will not contribute to workers fatigue

Optional tests:

Vibration testing Assures that the product is not damaged by vibration
Viable and non-viable particle count See clean room section for more detail
Pressure decay and cabinet integrity test Assures no contamination escaping through welds and joints

Fume Hoods – FH

Chemical fume hoods are used to contain and exhaust chemical vapors. They come in different types and designs for different operations. Airflows in fume hoods are imperative for safe operation. SEPS offers airflow velocity tests and smoke patterns visualization tests as means of documenting a fume hood performance. Periodic testing, preventative maintenance and inspections can provide your facility a complete program for fume hood management.


Method of testing performance of laboratory fume hoods. There are different test procedures incorporated into ASRAE 110 test:

  • Inflow Velocity Test with proper grid.
  • Smoke Patters Visualization Test.
  • Tracer Gas Containment Test

Animal Research Products

SEPS offers testing of animal transfer stations, waste disposal units, necropsy units and clean benches. Testing of these units ensures our customers of optimum productivity, versatility and safety of your research animals. Transfer stations are designed to provide animal protection and particulate control during routine cage-changing operations in the laboratory.

Periodic certification is necessary and will provide proper operation and safety for your lab animals. Contact SEPS to schedule a visit risk assessment and offer proper certifications guidelines.

SEPS also certifies and repairs:

  • Animal Racks
  • Containment Racks
  • Other types of animal containment units

Laminar Flow Units – LFU

A laminar flow clean bench provides a working environment that has its own filtered air supply. In many cases clean benches or LFU’S provide ISO class 5 environments. Virtually particulate free work area for conducting procedures.

Laminar flow units prevent any contaminated room air from entering the work area and contaminating samples.

Laminar flow units do no protect users from exposure and should never be used when working with any infectious material or volatile toxic chemicals.

SEPS certified LFU’s to (IEST) Institute of Environmental Sciences and Technology guidelines and recommended practices. IEST-RP-CC-002 is the current version.
