UnicornBag Clamp

The UNICORNBAG CLAMP® hermetically seals the opening of a mushroom grow bag or a spawn bag and eliminates the need for a sealing machine and all its problems. These seals are reusable with a no hassle simple design. This allows your bags to be easily reusable, autoclavable, simple to use, allow easy spawning after autoclaving and cooling. Allows easy verification of internal CO2 content of bag without cutting and resealing, Allowing things you always wanted to do that you could not do when the bags are heat sealed.

UNICORNBAG CLAMPs® are available on our online store. Each UNICORNBAGCLAMP® requires 16 inches of tubing that is 3/8″ outside diameter and autoclaveable.  This tubing is NOT supplied with the clamps.  United States Plastic Corp. offers  a 3/8″ OD laboratory tubing that  will work under 15psi steam for 30 minutes at 121°C (250°F).
