Inoculation/Filter Port Lid For Widemouth Mason Jars

Brand - Spores Lab

This pre-assembled and reusable lid fits a "widemouth" mason jar (90mm), and is equipped with a heavy duty self healing injection port, and a 0.2 micron filter.

The self healing injection port makes inoculation almost error-proof, while the 0.2 micron filter port keeps contaminants out of your mushroom spawn jar but allows adequate air & gas exchange for optimal colonization speed.

These lids are reusable and can be sterilized several times without warping or deforming. All components are 100% autoclavable.
