Whirl-Pak® sterilised filter bags are designed to simplify clean pipette collection. The 330 micron filter layer contains solid particles to one side of the bag preventing pipette blockage for a clean sample and even plate distribution. They provide a secure, contaminant free flexible container that ensures dependable analysis results. You can count on Whirl-Pak® products as a proven, economical and efficient way to collect, store and transport samples.
