We love to experiment here at The Fungal Jungle and are always looking for ways to improve our process, so we're offering (in our not-so-humble opinion) the perfect reusable liquid culture lid for your mason jars.
Featuring a self-healing injection port and a 0.22μm hydrophobic filter for air exchange, these lids don't leak and take loads of sterilization abuse!
Our favourite part is they're dishwasher safe and the injection port can be easily removed and reinserted for extra deep cleaning if required. BONUS: no gasket!
Available in both standard and wide mouth sizes.
