Negative or Positive Pressure

HEPA Flexible (Softwall) Isolator


HEPA Filter Isolator Systems


Flexible film isolators for gnotobiotic research

Maximize use of limited laboratory space with two independent isolators in one footprint. Allows you to conduct two different experiments at one time. This isolator is also available as a single-tier (one isolator) and as either a negative pressure or positive pressure system.

The CBC Difference

The CBC difference includes our original lap-seam sealing process and the use of 20 mil. polyurethane material that is almost indestructible and helps ensure against contamination due to accidental puncture or tear.

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. Because your reputation, research or production should not risk being compromised!    (See, "Pull Test" and "Puncture Demonstration" videos below.)
