Air Filter Vent: Ensures gas exchange while preventing contamination through its 0.22-micron filter, blocking all contaminants but allowing the passage of oxygen and carbon dioxide.

Self-healing Injection port: This durable, autoclavable silicone port permits repeated needle entry and has proven resistant to alcohol sprays before inoculation.

3M Primer: Strong adhesive backing resists autoclave temperatures, ensuring secure and lasting attachment. Covering with foil during sterilization is recommended to prevent moisture intrusion.

Marble: Ideal for breaking up Mycelium if a magnetic stirrer is not available. Use gentle swirling actions to avoid damaging the jar.

Magnetic Stirrer Bar: Designed to break up Mycelium effectively; larger bars are recommended as they are less likely to be thrown to the side during stirring.
