Microporous filter patch allows contaminant free gaseous air exchange. Filter effective to 0.2 microns and is ideal for clean sterile spawn production.
Measures: 18" high * 5.5" wide * 4" deep.
These bags are not intended to be sealed before sterilization, however they can successfully be sealed before sterilizing if the following conditions are met: All excess air is removed from the bag, excess bag material is neatly folded around the bag or secured with a clothes pin, and the bags are allowed to cool slowly and completely before removing from the sterilizer. We have successfully "presealed" and sterilized these bags for years without ruptures when following these precautions.
If you desire a higher vent filter bag, please see our Medium Presealable Autoclavable Gusseted Bulk Spawn Bags - 5 micron.
Bags now feature a thicker wall of 3mil, compared to other "standard" 2.5mil wall bags. Thicker bags require more material, and material costs are rising in all industries, but we will continue offering these bags as cheap as possible.
