These lid filter stickers are a great way to create a breathable, and auto-clavable jar lid. The 3M sticker is highly reliable and can withstand moisture and many cycles of going through the autoclave.

LightningSpore Note: We use these particularly for liquid culture media bottle lids, and they work great! We cut a 1/4 inch hole into a media bottle lid, deburr and clean the cut, and then put one of these stickers on the top and bottle of the lid.
