Microppose Adhesive Jar Filter Discs, Pack of 50

These filters can be applied to jar lids or tissue culture containers to allow your culture to breathe while protecting it from contaminant spores and bacteria. Great for projects involving injections or transfers.

Perfect for jar mycology and culturing mushroom spawn, these adhesive filter discs allow for optimal airflow into the jar with no worry of contamination. Fully Autoclavable.

Adhesive jar filter discs allow for air exchange to promote mycelial growth while preventing unwanted spores and airborne particulates from entering sterile grain spawn or liquid culture. Air exchange promotes stronger mycelium and more rapid growth.
