AttractSPE®Prefilters are prepared from depth-type media to increase throughputs. They are placed directly on top of a membrane filter or a SPE disk. These filters trap particles within the matrix and therefore have a high loading capacity.

AttractSPE®Prefilters Glassfiber are made from glass microfiber 100% borosilicate and have a high particle loading capacity for a fast filtration.

Several prefilters sizes are available for instance 25, 47 and 90mm. A first prefilter of 3µm followed by a prefilter of 1µm is advisable before a membrane filter or a SPE disks for dirty samples with suspended particulates.
