Media cap (20 PACK)

The end-all liquid media cap. Maintain sterile procedure with the best liquid culture cap in the market. Developed for commercial and home growers alike. Spore vision liquid culture threaded lid design can be cleaned in between runs and will maintain sterility. NO SUPER GLUE, NO SHORT CUTS!

These media caps are designed for use with liquid culture jars and media bottles, providing a secure, breathable seal during sterilization and incubation. Each cap includes a self-healing injection port, allowing for sterile syringe access without removing the lid — reducing contamination risk during inoculation.

Specs

• Compatible with: Standard wide-mouth mason jars and media bottles (confirm thread size against your jars before ordering)
• Material: Autoclave-safe, designed to withstand standard sterilization cycles

Why a 10-Pack

For anyone running multiple liquid culture jars or grain spawn jars at once, having a stock of caps on hand removes a common bottleneck — waiting on replacement lids between batches. A 10-pack covers a full round of jar prep in one order, which is especially useful for researchers and growers scaling up beyond single-jar setups.

Care & Reuse

These caps can be reused across multiple sterilization cycles as long as the septum remains intact and the seal stays tight. Inspect each cap before reuse for wear around the injection port, since a compromised septum increases contamination risk during inoculation.
