250ml Liquid Culture Jar with Injection Port and Filter

This isn’t your average LC jar. It’s the Kilner, the daddy of all jars, fitted with a lid that means business. Each one comes with an 18 mm Micropose self-healing injection port and a 0.3 µm waterproof filter that keeps your mycelium breathing clean while telling contaminants to do one.

We’ve used these jars for years and pushed them through more pressure cookers than we care to admit. They’ve never failed. Perfect for brewing liquid culture that actually grows instead of turning green.

• 2500ml Kilner glass jar – thick and bombproof

• 18 mm Micropose injection port – self-healing legend

• 0.3 µm waterproof filter – perfect airflow, zero contamination

• Fully autoclavable and pressure cooker safe

• 70 mm interchangeable plastic lid – fits Kilner, Ball, and Mason jars

If you want clean, fast, and consistent results, this is the jar you’ll end up using anyway. Might as well start with the good stuff.
