Whirl-Pak® Filter Sterilized Bags

Whirl-Pak® Filter Sterilized Sampling Bags provide a secure, contaminant free flexible container that ensures clean pipetting for dependable results. The bag features a full-page 330 micron filter layer that contains solid particles to one side of the bag, preventing pipette blockage for a clean sample and even plate distribution. The filter layer has a hole diameter of 0.33 mm (0.013 inches) with 285 filters per square cm (1,840 per square inch). The filter is sealed into the perimeter of the bag on the sides and bottom, allowing the sample to be placed in the bag on either side. The bags are sterilized through post-manufacturing sterilization (+1 Sterilization). Features include Write-On labeling, leak-proof continuous perimeter seal, and extreme film clarity and strength.
