Disposable; no extensive setup or Clean-Up required Biologically safe materials of construction Extends the life of the final filter The Versapor serum capsule is specifically designed to maximize throughput in applications where a heavy particulate load is common, such as in serum filtration. The capsule incorporates two layers of filtration media: a glass fiber prefilter followed by a Versapor (acrylic copolymer) membrane. The glass fiber filter uses depth filtration to extend the life of the filter, maximizing throughput while removing the majority of the particulate. The Versapor membrane assures that glass fibers are not shed downstream.
