Quality Commitment

Quality Commitment

CBC is committed to manufacturing the highest quality isolators, cleanrooms, containment units and components for animal research and pharmaceutical production.

The management and staff of Class Biologically Clean, Ltd. are dedicated to the continued improvement of our design and manufacturing processes. We understand the need for vigilant quality control to meet our customers' exacting specifications to help ensure the integrity of their research and/or controlled production.


Quality Tested from Start to Finish

CBC uses double polished clear vinyl plastic. All of the vinyl and polyurethane plastic is manufactured under ISO standards. Our initial visual inspections result in an average of 25% of the vinyl that we purchase being rejected due to cosmetic imperfections.

Every day and every time there is a tool change, the machine is recalibrated and tested for optimum performance checking melt, pressure and time to ensure that we obtain the best, uniform seam seal possible. We trim all our materials with surgical scissors for sharper, cleaner cuts.

CBC uses a highly durable "lap seam" seal for the majority of our seams, and an even superior "cut/weld/strip seam" seal for high risk areas. We visually inspect the seams for obvious imperfections such as bubbles, opaqueness and ridges. We finish with a "pull" test that would make many of our competitors cringe. The fact is, our workers inspect every step of the production process including: cutting, trimming, seams and even cleaning. Starting with the plans, patterns and reviews, all the way through production, we inspect and double inspect to ensure that we produce the highest quality, flexible film, germ-free products possible.


No "Cookie Cutter" Design Solutions

CBC is customer focused. We work closely with our customers to design and manufacture flexible film and semi-rigid, germ-free isolators, cleanrooms and containment units that provide the needed security and protection they require at prices that won't break their research or production budgets.

CBC Products are Made in the United States

Our quality control practices have been developed over our 44 years in business - listening and learning from our highly educated and diverse client base.

We stand behind our products and will work with you if they do not perform as expected.
