Description
Autoclavable Mason Jar Regular Mouth Mycology Lids (70mm) with Self-Healing Injection Port and Air Filter Vent for Liquid Culture and Grain Spawn Cultivation
This model also comes in the wide mouth (86mm) version.
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.
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 regular mouth lid includes an 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 since they are made of plastic.

Item Specifications:
- Mason Jar Lid (White): 70mm outer diameter mouth jar (fits small 4oz regular mouth jars to 64oz regular mouth jars)
- Air Filter Vent (White): 0.22 micron, 3M adhesive backing, 1.8 cm x 1 cm
- Self-Healing Silicone Injection Port (Black): 3M adhesive backing, 1.8 cm
Air Filter Vent:
This air filter vent provides gas exchange in culture containers while preventing contamination. The 0.22-micron filter blocks all contaminants but allows the passage of oxygen and carbon dioxide (the smallest contaminants are 3 microns). This product is long-lasting, highly durable, and autoclavable, widely used for grain jars and liquid cultures.
The self-healing silicone injection port allows a needle to pass through while self-healing. It is autoclavable and long-lasting. Multiple times, we have sprayed alcohol on this product before inoculation, and it has shown no signs of deterioration. It is easy to clean and has a simple but elegant design, unlike homemade self-healing injection ports.
What makes these items efficient and secure is the strong 3M adhesive. It can resist autoclave temperatures over 121°C at 15 psi for extended periods when kept covered and dry during sterilization (we have proven it withstands higher psi, but it is not recommended for long-term usability). We recommend covering the jar with foil paper to avoid water/steam getting inside.
Usability:
- Grain jars
- Liquid culture jars
- PF TEK culturing
