Microppose Adherable Lid Filters For Plant & Mushroom Tissue Culture

Adhesive-backed microporous filters that turn any jar lid or tissue culture container into a breathable, contamination-resistant vessel. Peel, stick, and the vessel exchanges gas while blocking airborne spores and bacteria.

Mycelium produces carbon dioxide and needs fresh air to colonize properly, but every opening is an entry point for green mold, cobweb and bacterial contamination. A 0.3 micron filter resolves that: air moves, contaminants do not. Applied over a drilled hole in a lid, it replaces stuffed polyfil and tape with something repeatable and far faster to install.

Specifications

• 0.3 micron filtration efficiency
• Strong 3M adhesive backing
• Hydrophobic and oleophobic — sheds water and oils
• Fully autoclavable, high-temperature resistant
• Made from 100% recycled material
• Applies in seconds, no tools required

Used for: grain jar lids, liquid culture vessels, agar and tissue culture containers, spawn jars, and any project involving repeated injections or transfers.

Apply filters before sterilizing — they are rated for autoclave temperatures and can go through the cycle in place. Pair with our self-healing injection ports for a complete breathable, injectable lid, and verify every load with sterilization indicator strips.

Available in packs of 50, 100, 250 and 1,000.
