Peel-and-stick self-healing injection ports for anyone building their own jars and spawn bags. Stick one on a jar lid or bag, pressure-sterilize as normal, and inject or draw culture through it as many times as you need. The silicone and EPDM port reseals behind the needle, and the high-temp 3M adhesive holds through the cooker.
Turn any metal or plastic jar lid into a liquid culture or grain jar lid you can inject and draw from without opening.
High-temperature silicone over EPDM foam closes behind the needle, so one port handles repeated injections and culture pulls.
The high-temp 3M adhesive backing is made to stay put through autoclave and pressure-cooker cycles.
Clean and dry the jar lid or bag where the port will go so the adhesive grips fully.
On a lid, punch a small hole and center the port over it. On a bag, stick it above the grain line.
Pressure-sterilize the jars or bags with the ports already in place.
Wipe the port with alcohol, flame your needle and go straight through the center.
From our lab: press the port down firmly and run your finger around the edge before it goes in the cooker. A good seal at the edges keeps contaminants from wicking in under the port.

Yes. The silicone, EPDM and 3M adhesive backing are rated for autoclave and pressure-cooker temperatures. Apply the ports before you sterilize.
The port reseals after each puncture, so you can inject and draw culture repeatedly. Replace it when it no longer closes cleanly behind the needle.
Above the grain line, on a flat, clean area of the bag, so the needle reaches the grain without tearing the bag.
