Because Your Reputation, Research or Production Should Not Risk Being Compromised!

The polyurethane material used by CBC is almost indestructable.     The Lap seam sealing process used by CBC is stronger than single seam seals.

The polyurethane material used in our softwall containment isolators, cleanrooms and containment units is almost indestructible and helps ensure against contamination due to accidental puncture or tear. What's more, our lap seam sealing process is more durable than single seam seals. Widely used for sterile manipulations, CBC isolators provide uncompromised, continuous isolation of its interior from the external environment.
