Description
Autoclavable Wide-Mouth Mason Jar Lids (86mm) with Self-Healing Injection Port and Air Filter Vent for Liquid Culture and Grain Spawn Cultivation
Frequently Asked Question: 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 etc.
However, please note that non-branded jars from other big stores 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 website of the retailer where you purchased your jars or planning on purchasing your jar and confirming whether your jars are labeled Regular Mouth or Wide Mouth.
This model also comes in the Regular Mouth version (70mm).
Note: These lids do not require a silicone gasket.
Save time and effort from drilling holes in 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 while remaining sterile. Both the filter and injection port have a strong adhesive that can withstand autoclave temperatures over 120°C (250°F) at 15 psi for extended periods. Unlike metal lids, these lids do not rust as they are made of plastic.
