B&L Testing and Balancing is a certified provider of controlled environment testing within the manufacturing and life science industries.

Our goal is to help our clients achieve and maintain regulatory compliance through rigorous and regular standardized testing with an emphasis on customer service and urgency.

We understand how costly shutdowns and environmental control issues could be.  From spoiled product to contaminated personnel, a poorly performing controlled environment can have very serious consequences.  Trust our qualified team of technicians to provide you with the expertise and resources needed to keep you safe and on track.

Cleanroom Performance Testing

Cleanrooms are used throughout the medical, pharmaceutical, and semiconductor industries. These rooms must meet regulatory ISO 14644 standards of performance and be regularly tested to confirm compliance.

Pharmacy Compliance

The regulations comprising USP<797> and USP<800> were created to protect patients by preventing the contamination of compounded sterile preparations.  Our dedicated team can provide the necessary and rigorous semi-annual testing to achieve and maintain compliance.

Biological Safety Cabinet and Laminar Flow Hood Certification

Biological safety cabinets (BSCs) are field tested in accordance with NSF/ANSI 49 and manufacturer's specifications. BSC's and laminar flow hoods should be certified at least every 12 months.

Viable and Non-viable Surface and Air Sampling

Controlled environments need to follow and adhere to strict regulations that dictate the cleanliness and maintenance of rooms and manufacturing areas. In order to control the amount of possibly pathogenic organisms, viable air and surface sampling should be performed regularly.

Decontamination Services

When it comes to the decontamination of biological safety cabinets, incubators and other laboratory equipment, our experienced technicians deliver consistent decontamination results

HEPA Integrity Testing and Repair

The HEPA filter integrity test is typically performed on supply air or exhaust air HEPA filters using a photometer to scan the filter surface for pinhole leaks that could allow the transmission of contaminant particles
