We offer a selection of replacement gas exchange lids. These Breathable lids are essential for your spawn jars or liquid culture jars, offering optimum gas exchange as well as a rubber injection port for easy inoculation.

Two types available, liquid culture lid and Rye grain/spawn lid, both autoclave safe and reusable. Select from the drop down menu above.

Please note: these lids fit standard Kilner jars only (70mm diameter mouth) and this listing is for the lid only. The metal band, which comes standard with all Kilner style jars, is not included. If in doubt, you can purchase a complete jar here form our other listing.
