The UnicornBag Clamp® hermetically seals the opening of a mushroom grow bag, and is excellent for hobbyist mycologists who do not possess an Impulse Heat Sealer. Use this clamp to seal spawn and substrate bag prior to sterilization, and easily remove it to inoculate or mix spawn and substrate.
The clamp is reusable and autoclaveable. It is simple to use, all you need to do is clip the clamp around the 3/8" OD tubing included with the clamp.
