Autoclavable wide-mouth mason jar lids 86mm with self-healing injection port and air filter vent for liquid culture and grain spawn cultivation.
This mode also comes in the Regular Mouth Model 70mm.
The new lids are equipped with a silicone seal housed within the lid. Please ensure that the silicone seal remains properly seated when closing the lid, as it may occasionally shift or fall out. A quick visual inspection before closing will help prevent any issues. The injection port and air filter on these lids are replaceable. Just apply primer and replace the injection port and air filter as required, depending on use. It is a great idea to tilt the jar and check for leakage before and after adding it to the steriliser. If the leakage is from the injection port or the air filter, press it down firmly for 5-10 seconds, and it will do the job.
Tip-The air filter and injection port will get immense pressure from the water that’s changing to steam in the steriliser. We let the jars sterilise and cool down. Before taking them out, we make a gentle push on the air filter and injection port for them to stick back if they came loose.
Will your lids fit all Mason jars?
Our lids are designed to fit mason jars labeled as Regular Mouth (70mm) or Wide Mouth (86mm). These are standard sizes, and they will fit popular branded jars like Ball, Kerr, Aussie Mason etc.
However, please note that non-branded jars from stores like Big W, Kmart, or Coles may not be the same size and our lids may not fit them.
Before purchasing, we recommend ordering a single lid to test the fit. You can also check your jar’s size by visiting the the website of the retailer where you purchased your jars or planning on purchasing the jar and confirming whether your jars are labeled Regular Mouth or Wide Mouth.
This way, you can be sure our lids will work with your jars.
Save time and effort from drilling holes on Mason Jar lids. These Lab-class mason jar lids are designed specifically for liquid culture and grain spawn cultivation. The wide mouth lid includes a Microppose injection port and a micron air filter. The injection port allows the needle to pass through multiple times while self-healing. The micron air filter has a vent of 0.22 microns, allowing the appropriate exchange of gases whilst remaining sterile. The filter and injection port have a strong adhesive that can withstand autoclave temperatures of over 120 Celsius (250F) at 15psi for extended periods. These Lids do not rust, unlike metal lids, since they are made of plastic.
