Filter Bags contain a third layer of finely perforated polyethylene film, which filters out solids in the blended sample, allowing for easy pipetting of the liquid. Available with standard and vertical filters.

Standard Filter Blender Bags
Filter Bags contain a third layer of finely perforated polyethylene film, which filters out solids in the blended sample, allowing for easy pipetting of the liquid. The hole diameter in the filter layer measures .013 inches (.33 mm), 330 microns, and there are 1,840 holes per square inch (285 per square cm). The filter layer inside the bag is sealed into the sides and bottom perimeter, allowing the sample to be placed in the bag on either side. Liquids of a blended sample will transfer through the filter, while solids remain on one side.

Vertical Filter Blender Bags
Bags use a special laminated PET film for durability and a vertical non-woven filter to separate solids for easy pipetting of the liquid sample. Available with or without a closure, each bag contains a 250 micron polyester filter adhered vertically along the side of the 3 mil (0.76 mm) bag. Easy-pour side seal allows you to simply pour liquid out of the bag without also emptying solids.
