Advanced Liquid Culture Lid — Wide Mouth Mason Jar

A cleaner way to inoculate and store liquid culture — no drilling a jar lid, no separate injection port to install. This self-healing injection port lid gives you sterile syringe access every time, paired with an air filter patch that lets your culture breathe without letting contaminants in.

Fits Wide Mouth (86mm opening) Mason jars — both 16oz and 32oz, since the mouth size is standardized independent of jar volume. Durable white plastic construction, built for repeated sterilization and reuse across many liquid culture and grain spawn cycles.

Each lid: self-healing injection port · air filter patch · compatible with standard Wide Mouth Mason jars.
