Modified Mycology Lid (Wide Mouth)


In stock

SKU: 127 Category: Tag:

This item is a plastic one piece lid for wide mouth jars (Ball, Kerr, etc). It can be autoclaved (sterilized) 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.

Great lids!

These work great! Well built, and worked awesome in the pressure cooker.

Jacob Gordon
Love the top!

Love the mason jar lid. Works perfectly, and keep contam out. My only “complaint” is that I wish the Gas exchange hole was a tad larger.

Ordered a few to test out, now I'm back for more

I ordered three of these to test them out, and I'm immediately coming back for more. I don't think I can go back to my old ways after using these!

a creative solution to an undercooked problem

its simple, it does the job
I like how the injection site reseals and you don't have to worry about contamination
no more flipping the lid waiting on my oysters!

Not yet, but good to go

I haven't used it yet, but my product came in promptly and in good order. I will order other things from this vendor.
