BM Life Science，Ultrafiltration Centrifugal Tube (Centrifugal Filter) Series Products

It consists of an inner filter tube (with membrane) + an outer centrifuge tube, which can quickly and effectively purify and concentrate up to 15ml of biological samples. The unique vertical design and maximized filtration area can provide fast sample processing capacity and high sample recovery rate (usually ≥90% dilute original solution), while maintaining a mild filtration and concentration environment to maintain protein activity and Conformation.The unique vertical design can polarize the solute and significantly reduce the fouling of the filter membrane caused by subsequent centrifugation. By optimizing the physical filter stop point in the filter device, it can prevent the centrifugal filter from drying out the sample or causing sample loss due to excessive rotation. . A variety of ultrafiltration molecular weight cutoff (MWCO) centrifugal filters use high-purity, low-adsorption PES and RCE membranes, which have extremely low protein and nucleic acid binding rates.

Recovery rate

The retention capacity of the 15ml ultrafiltration centrifuge tube membrane is described by the molecular weight cutoff (MWCO).

Solute molecular weights close to MWCO may only be partially retained. In order to obtain the best retention characteristics,         

please use a MWCO filter membrane with a molecular weight of 1/3 or less than the solute.
