Injectable Spawn Jar Lid - PP5
Regular Mouth - 70 mm

This spawn jar lid will fit all regular mouth (70 mm) canning jars. It is intended to be used atop jars of live spawn or mycelium. The lid is equipped with a super heavy duty injection port and a 0.3 µm synthetic filter disc (29 mm diameter) that allows for contaminant-free gas exchange. The lid and all components are 100% autoclavable.

The heavy duty injection port is of the highest quality and is able to withstand hundreds of repeated injections before needing to be replaced. The synthetic filter disc is factory-cut and 100% reusable. The lid itself is made of a thick autoclavable PP5 polypropylene plastic. This lid will form an airtight and watertight seal when screwed firmly on the jar.

These are fantastic! They are fully worth the extra cost for being contamination free. By the way, you really only need a single injection port, you can move the needle around and get a few drops in a circle or just do a single drop, the spread is fast enough! Only question I have is, do I have to cover the tops in foil while they are in the pressure cooker or not? Thank you guys for making mycology a lot easier for the layman.
