Add a resealing injection port to any lid or bag.
Turn any jar lid or spawn bag into a permanent injection point. Each Microppose port is a self-healing silicone/EPDM pad with 3M adhesive: stick it on, sterilize as usual, and push a needle straight through. It seals itself after every puncture, so you can inoculate again and again without opening the jar. The pack has 25 ports.
The membrane closes after each needle puncture.
Stick it on; there is no hole to drill or separate filter to fit.
The rubber and adhesive hold through repeated pressure cycles.
Press a port firmly onto a clean, dry lid or bag.
Pressure sterilize as normal.
Wipe the port with alcohol and push the needle straight through.
Inject again later; it reseals each time.
Ready-made lidsWide mouth jar lids with filter and injection port come with ports already installed.
Yes. The material and adhesive hold through repeated pressure sterilization.
No. Stick the port on and the needle goes straight through it.
Metal or plastic jar lids and spawn bags.
For the moderate user they are very easy to use and keywords "easily replaceable" they create the port on a bag and work very well on jars too
These were something I gave a chance for my LC jars. I’m glad I did because they work perfectly as described. I put 2 per lid and they have worked contam free with multiple uses.
easy to use.. Just stick it were the old one was, or use it on a newly drilled lid.
Works great. Piece of mind
Works perfect with my bags, and there local.
