Game changers for liquid culture jars
These are game changers for liquid cultures for mushroom cultivation. Super cheap for how easy they make sterile spore and LC transfers.

Worked flawlessly.
100% success with zero contaminates. No problems being pressure cooked at 15psi for 90 minutes. The ports can be used multiple times, but they're so cheap I use new ones each time. 100 for $10 is an excellent buy.

Fast shipping and packaged good
Fast shipping product as described and great price. Can’t really complain but made of a harder rubber than the higher quality product vacutainer type. Would buy again in a pinch

How to puncture jar lid for proper fit
15/32 bit running drill in reverse for a clean puncture. Run reverse from topside. It will be a friction hole. Light cleanup on backside but stopper will seal perfect. Love the fit and seal
