Modified Mycology Lid (Wide Mouth)

This item is a plastic one piece lid for wide mouth jars (Ball, Kerr, etc). It can be autoclaved (including pressure cookers at 20 psi) and used for grain, agar, or liquid culture (LC) jars.

The lid is modified with a 1/4″ hole covered with a filter for gas exchange and a self healing injection port. The port location is easily identified by a mound (see photo below).

These are made in house and are the same ones MMM uses to prepare gourmet grain spawn, gourmet LCs, and distilled water for spore syringes.

We always recommend using large gauge needles (small bore) to reduce damage to the self healing injection port. When treated correctly the port should last for at least 25+ injections and sterilization cycles.
