Modified Mycology Lid (Wide Mouth)


In stock

SKU: 1150 Category: Tag:

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.

These lids are high quality and the self healing port does exactly as it should!! Will definitely be ordering more!

Great vendor, great lids!

I was skeptical at first and ordered the lids on a whim as they appeared in my cart check out. I figured what the hell and grabbed four of them. What I think is most important to point out is that, while these are handmade, they have a quality to them that feels professional/commercial grade. My own attempts at making such lids worked sure, but they didn’t look great. These are made by a practiced hand, everything fits together seamlessly, and they are all around awesome! I will most definitely be purchasing these as my exclusive lid for all of my jar cultures of the various species I grow. Add to that that MMM is very pleasant and makes it feel as though you’re ordering from a friend rather than some random business online. 10/10 would recommend to anyone! The freebie I was given was unexpected and also hilariously creative on the part of MMM. One happy amateur mycologist right here :)

Awesome Product

I’ve placed multiple orders with Mushroom Man Mycology and continue to be impressed! Customer service and products are always top notch! Can’t wait to use the lid!
