Product Description

The use of medical grade vial stoppers, mushroom grain spawn and liquid culture jars, plus hypodermic needles to inject cultures, is described.

The fabric is made of grey Butyl rubber, steam sterilization safe, -50 to 250 degrees Fahrenheit

The stopper measures 13mm in diameter and fits 1/4 inch or 7mm holes

To grow mushrooms, create self-healing injection ports using lids for mason jars or PP plastic containers by using stoppers with a mason jar or PP plastic container clamps.

Packet is 110 PER BOTTLE packaged in an easy to use jar so you'll always have a port on hand

Selected User Reviews For 20mm Rubber Self Healing Injection Ports - Commercial Butyl Bottle Stoppers, 110 Pack, Mason Jar Lids, Mushrooms, Vials, Steam Sterilization Safe, for 1/2 Inch or 13mm Opening

The jar is full of injection ports, that's cool

5/5

It's nice to have a jar instead of a baggie for such a low price. The through hole does not have a recess for keeping it in place. at the end of the day, it seemed to make no difference. I recommend going with 7/16" drill bit instead of 1/2" despite the label that tells you to use 1/2".

It is hard to use good quality materials

4/5

Although I liked the idea of making my own, it's hard to drill through a lid without messing up the drill hole and ruining the project. Maybe I should buy a hole punch so I can punch straight through.
