70mm Autoclavable Plastic Lids (For Mushroom Spawn Grain Jars or Liquid Culture)

This product is just the lid, no jars included as you’ve probably got your own (although if you want to buy a Kilner jar or a jar/lid bundle from us then they’re here).

Suitable for normal mason jars often used for liquid culture production, for grain spawn jars, or for rockin’ it old school and doing some PF Tek cakes.

If you don’t feel like buying a load of empty jars then the Bonne Maman ones full of jam are pretty decent as they don’t narrow at the neck (makes it a bit easier to get your grain spawn out), although for them you’ll want the larger size lids that we sell which are here.

Don’t fancy drilling holes and putting your own ports and filters on? Cool, we can sort that too. And you can even get them a bit cheaper if you want five at a time!

Three options:

1. Lid Only (does what it says on the tin)
2. With Microppose injection port and filter, pre-drilled with the port and the filter ready to go!
3. Same as 2 except there’s five of them and it isn’t five times the price!
