North Spore Autoclavable Disc Filters for 'Wide Mouth' Mason Jar Lids - 12ct

 Filter 0.3 micron

Autoclavable? Yes

These 90 mm synthetic 0.3 micron filters are sized to fit perfectly between a mason jar lid and band. Ideal for jar culture, these filters allow air exchange while keeping contaminants out. Simply poke one or two 3/8" to 1/2" holes in the canning jar lid and then place the filter on top and secure with band.

Filters are sterilizable and reusable. A self-healing injection port can also be attached to the filter.
