Our professional grade autoclavableRejular andwide mouth jar lids are built to be lab-quality, and made specifically for liquid culturing.

Our lids feature super heavy duty medical grade self-healing syringe injection ports, and we seal each hole with high temperature silicon. Liquid Fungi lids last twice as long as our competitors. Each lid comes with a reusable silicon gasket ring for an airtight seal.

This type of lid must be left a 1/4 turn open when pressure cooking, and fully tightened when cooled.

Set of 6 mason jar lids for making mushroom liquid cultures. The polypropylene lid features a rubber self healing injection port, a high quality .22 micron filter and a silicone gasket to unsure a tight seal. Leave the lids a quarter turn loose while in the pressure cooker so air can escape, otherwise the injection ports will pop out. These lids can be used in a microwave, autoclave or pressure cooker.
