The perfect rubber plug for your grain spawn or liquid culture lids. These plugs allow a needle to penetrate the jar with minimal risk of contamination, making sterile work much easier to accomplish without the aid of a laboratory environment. The self-healing properties of these plugs allow them to be used many times without replacement. 

These fit snugly into a 1/4" (6mm) hole.
