Self-healing 13mm injection ports for building your own liquid culture or grain jars. Each port creates a resealable membrane that allows repeated syringe injections without compromising the jar's sterility, making them ideal for liquid culture (LC) jars, agar work and grain spawn jars.
 
Simple to fit into a drilled lid using silicone sealant, and compatible with most standard syringe needles.
 
Available in packs of 10, 25 and 50 to suit occasional and high-volume use.
