VectaSpin™ Micro centrifuge filters are supplied with a range of filtration and separation media. They are 400 µl volume and are produced from pigment free polypropylene to eliminate sample contamination. A 10.0 µm mesh is available for the filtration of coarse particulates and are also available with a range of ultrafiltration membranes which can separate macromolecules, such as proteins, based on differences in their molecular weights.
The centrifuge filters are compatible with all common centrifuge rotors and holders. Filtrate can be stored in the receiving tube after centrifugation eliminating the need for a separate storage tube.
Features and benefits

The cellulose acetate and polysulfone membranes contain glycerin as a wetting agent. This may be removed if necessary by prerinsing with distilled water or buffers. Transparent spots may appear on filters under higher levels of humidity. These are due to the glycerin and do not affect the peformance of the filter.
