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.
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
