Liquid Culture Plastic Wide Mouth Mason Jar Lids

Our plastic autoclavable wide mouth mason jar lids are built to be functional and affordable. Designed specifically for liquid culture cultivation, they feature a hydrophobic PTFE filter which can be held upside down and not leak. Our lids feature super heavy duty medical grade self-healing injection ports, and we seal each hole with high temperature silicon. Each lid comes with a reusable silicon gasket ring for an airtight seal. This type of lid must be left a 1/4 turn open when pressure cooking, and fully tightened when cooled.
