NEST Disposable Vacuum Filtration System is useful for sterilizing the large volume sample for tissue culture media and many other biological buffers which cannot be autoclavable. The unit includes PES membrane filters with graduated filter tops made with polystyrene, and Acrylonitrile-Butadiene-Styrene necks with polystyrene receiving bottles. A separated sterile polyethylene cap is included. Filtration system is manufactured from raw material of highly transparent polystyrene (PS). Filtration system comes in three different volumes: 250mL / 500mL / 1000mL.
It is mainly used in tissue culture media and biological fluids for separation and purification of large volume samples. The whole set includes membrane diaphragm, a graduated, transparent polystyrene funnel connected to a receiving bottle by a connector. The disposable vacuum filter utilizes a vacuum pump to provide pressure differentials for processing large volumes of tissue culture fluids and other laboratory fluid solutions and the volume of processed samples could be up to several liters. The filtered samples can be stored directly in sterile collection bottles.
