6 Mason jar lids for making mushroom liquid cultures. 6 for $25 with USA free shipping. 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. These lids can be used in a microwave, autoclave or pressure cooker. They fit wide mouth mason jars. Mason Jars are NOT included. Check out Mycovations on YouTube (Search "How to make Liquid Cultures for Mushroom Cultivation" to find my video) Leave the lids a quarter turn loose while in the pressure cooker so air can escape, otherwise the injection ports will pop out.

Looks good but not functional
Does not autoclave well tried several times 15psi at 20mins. Lids popped off 3 out 6 during autoclave.Look nice but not very functional.

Handmade
These do not autoclave well. Lids start to deform. Syringe filters are just pushed in a hole. Easy for contam to get in. Am not planning on re-purchasing.

nice lids good color, cool
I like the colors, easy to organize when working with many unique cultures. Other than that you can make these yourself.

Lids don't fit any size mason jar- leaks and contamination every time I've used them.
I tried to use these lids for liquid culture mushroom cultivation.However, these lids do NOT seal properly on any of the 6 different size mason jars I've tried. They leak and cause contamination everytime.I would never reccomend these lids. Just buy the filters that these lids have seperately and drill holes in your jar lids to fit them.

Good deal
Great lids they work great and are exactly what I need for what I want them to do... Liquid cultures.. could be a little cheaper but whatever

Works great, and a lot easier to unscrew
Working great so far, no issues so far. We don’t use foil on top, and we fully tighten the lids with no issue of filters popping off. Not a single contamination so far. 👍

Purchased a 2nd set and will purchase again.
Very nice lids. Many compliments from people on pages. They took the pc at 15psi for 45min just fine. They include a different cute sticker every time too.
