Disposable bottletop aspirators provide a complete vacuum filtration solution for your separation and purification needs. Intended for the sterile vacuum filtration of aqueous solutions such as cell culture media and biological fluids.

All units come presterilized by gamma irradiation and certified nonpyrogenic, and are individually wrapped in easy-to-open packages. The large openings on the reservoir and funnel make for easy access. The housing (cup, bottle, and lid) are made of clear polystyrene for easy viewing. The filter tip is constructed of polypropylene, while the joint connector is made of Acrylonitrile Butadiene Styrene (ABS) and the cap material is High-Density Polyethylene (HDPE).

Surfactant-free cellulose acetate filter membranes contain none of the wetting agents found in standard CA (cellulose acetate). These wetting agents have been shown to be toxic to specific cell lines in vitro (1-3). SFCA also has lower protein binding than does standard CA.
