Autoclavable mason jar regular mouth lids with self-healing injection port and air filter vent for liquid culture and grain spawn cultivation.
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 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 .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. Unlike metal lids, these Lids do not rust since they are made of plastic.

*THERE ARE TWO TYPES OF MASON JARS- WIDE MOUTH AND REGULAR MOUTH. THESE LIDS ARE FOR REGULAR MOUTH MASON JARS*
- Mason Jar lid (White colour)- 70mm outer diameter mouth jar (Fits small 4oz regular mouth jars to 64oz regular mouth jars)
- Air Filter Vent (White colour)- 0.22 Micron, 3M adhesive backing-1.8 cm X 1 cm.
- Self-healing silicon injection port (Black) -3M adhesive backing- 1.8 cm.
This Air Filter Vent provides gas exchange in culture containers whilst removing the chances of contamination. That is due to its 0.22-micron filter, which blocks all contaminants but permits the entrance and exit of oxygen and carbon dioxide (The smallest contaminants are 3 microns). This product has proven long-lasting and highly durable; it is autoclavable and widely used for grain jars and liquid cultures.
Self-healing Injection port:
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 prior to inoculation, and it has shown no signs of deterioration. It is easy to clean and has a simple but elegant design, which homemade self-healing injection ports lack.
What makes these items efficient and secure is the 3M strong adhesive. It can resist autoclave temperatures over 121 Celsius at 15psi for extended periods when kept covered and dry during sterilization (We have proved that it withstands higher psi. However, it is not recommended for lasting usability). We recommend keeping the jar covered with foil paper on top to avoid water/steam getting inside.
