$10.00$70.00 inc. GST


Autoclavable mason jar wide 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 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.
