Made in the United States

The CBC difference starts at the bottom and works its way up. Two-way locking casters keep the table frame from moving while working with the isolator. 1 1/2" powder coated steel frame provides superior strength and durability. The 1 1/2" steel frame prevents sagging keeping the isolator level, and the powder coating provide superior protection against chipping or rust. The tabletop is made of 1/2" high-density polyethylene with inserts preinstalled for all filters, port and hold-down loop clamps. Next comes the 3/8" closed cell foam pad that the isolator sits on. Each system come comes with a blower and manifold with ball valve for adjusting the airflow levels. Our standard 5" diameter filters provide greater airflow throughout the isolator. This increased airflow results in better living conditions for the animals inside the isolator. An acrylic transfer port with a stainless steel base provides strength and more light for easier transfers. Each isolator is made of either 20-mil vinyl or 20-mil urethane film. Each isolator includes the CBC Glove Extension. The glove extensions help reduce the stress on the isolator and user. The glove extensions also increase the reach into the isolator. Inside the isolator includes a durable 20 mil urethane pad and a two nine cage polypropylene cage racks.

CBC "Starter Labs"


CBC gnotobiotic starter labs include a flexible film isolator system with all the hardware and accessories needed for researchers to install a fully functional germ free lab that offers complete environmental control for gnotobiotic, microbiome and other research. CBC "Starter labs" come with all the accessories and components required for researchers to establish a germ-free, gnotobiotic lab for viral, microbiome and microbial studies. They can be customized to meet a customer's individual research needs. Below are links to our standard "Starter Lab" packages to better give you an idea what is usually included in the packages.

Positive or Negative Pressure Isolator Units


CBC flexible, softwall isolators provide the maximum in both product and personnel protection.

Positive Pressure Isolators:   Product protection is provided using positive pressure isolators. Positive pressure isolators create pressurized chambers in which the air pressure inside the chamber is greater than the ambient room pressure. In the event of a breach, the air inside the isolator will be pushed out keeping contaminants out of the isolator, hence protecting the product inside the unit.

Negative Pressure Isolators:  Personnel protection and product containment is provided using negative pressure isolators. With negative pressure isolators the air is pulled out of the isolator, which creates a lower pressure inside the chamber than the ambient room pressure. An external frame is needed to prevent the chamber from collapsing. In the event of a breach, the surrounding room air is pulled into the isolator preventing any product inside the isolator from leaving the isolator (often called a containment isolator).

  • 30" x 2' x 2' – Single-Tier/One isolator.

CBC' Quality Control Tracking

Each CBC Flexible Film Canopy is Marked With its Own Unique Serial Number .

When you buy one of our gnotobiotic isolator systems or just a canopy, your canopy will be marked with its own unique serial number and manufacture date. Should you ever have a issue with the canopy (or need a replacement) CBC can trace your canopy back to the exact specs previously ordered. The same for replacement canopies for existing frames and filter systems.

  • Traceability.
  • Faster replacement.
  • More accurate replacement.

Each CBC Flexible Film Canopy is Marked With its Own Unique Serial Number and Manufacture Date to Ensure Traceability and Better Customer Support.

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.)

Improved Living Environment

CBC's lower filter inlet port and upper filter outlet port can more efficiently remove warm, moist air. What's more, our 5" diameter design (vs. competitive 3" diameter) provides greater airflow. The larger filter diameter combined with CBC's unique "inlet/outlet" port design help improve the isolator's living environment.
