6 pc. 'Wide Mouth' Culture Jar Lid with Port & Filter

Reliable culture work starts with equipment that supports clean technique. The 6 pc. “Wide Mouth” Culture Jar Lid with Port & Filter set is designed for mushroom cultivators preparing liquid cultures in standard wide-mouth mason jars.

Each lid is made from durable 304 stainless steel, providing strong resistance to rust and repeated-use wear. Compared with ordinary metal lids, stainless steel offers a dependable, reusable surface for ongoing culture work and routine lab handling.

The integrated injection port allows cultures to be inoculated with a syringe while keeping the jar closed, helping reduce unnecessary exposure during transfers. The self-healing port is suited to repeated inoculations when handled with proper sterile technique.

A built-in filter supports filtered gas exchange while helping limit the entry of airborne contaminants. This makes the lids useful for liquid culture applications where maintaining a controlled jar environment is essential.

Designed for wide-mouth mason jars, these culture jar lids are practical for home laboratories, classroom setups, and more advanced indoor cultivation workflows. Jars are not included, so pair the lids with compatible wide-mouth jars and use appropriate sterilization procedures before each run.

With six reusable lids in one kit, this set helps keep multiple cultures organized and ready for consistent mycology lab work. North Spore’s lab supplies are developed with the practical needs of indoor growers and contamination-conscious cultivators in mind.
