Work perfect for mycology
I use them when sterilize my substrate usually popcorn it works better than anything else I have found and easy to clean off the stems just break them off they make it where I can enoculate without contamination it's very important

Buy this one
Excellent. Exactly as described. Fits a 15/32 inch hole perfectly. Use a step drill bit for a super easy clean hole in a jar lid. Oreilly sells a kit that includes a step drill bit with the correct size. Best value for money. Excellent durability, I tested one by puncturing it 20 times. As long as you use slightly different spots it lasts easily 10-15 punctures with a 16 gage needle.

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

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.
