6 x 70mm Modified Mason Jar Lids for mycology, liquid culture jars, sterile solution preparation, mushroom cultivation, and clean culture work. Each lid is fitted with a 0.22 micron filter for sterile gas exchange and a self healing injection port for easier inoculation with liquid culture syringes.
These modified mason jar lids are ideal for growers who want a cleaner, faster, and more consistent workflow when preparing liquid culture, sterile media, and mycology jar setups.
🔥 Why Use Modified Mason Jar Lids?
6 modified mason jar lids included
A practical pack of 6 lids for setting up multiple liquid culture jars or sterile media jars.

Allows filtered gas exchange while helping protect the contents from airborne contamination.
Self healing injection port
Provides a clean access point for sterile needles and liquid culture syringes without needing to open the jar.
Ideal for liquid culture jars
Perfect for preparing and maintaining mushroom liquid culture in a cleaner, more controlled setup.
Reusable and easy to work with
A convenient upgrade for hobby growers, home mycology labs, and small scale mushroom cultivation.
Helps reduce contamination risk

🧪 Suitable for Mycology and Liquid Culture Work
These modified mason jar lids are designed for growers working with liquid culture, sterile media, agar testing, and mushroom cultivation workflows.
Each lid combines two key features:
0.22 micron filter
Supports sterile gas exchange during incubation and culture growth.
Self healing injection port
Allows you to inject liquid culture, spores where legal, or sterile solution using a syringe and sterile needle without opening the jar.
This makes them especially useful for reducing unnecessary exposure during contamination sensitive mycology work.
