Product Description
Concentrate precious protein samples without the worry of spinning them dry. CELLTREAT centrifugal filter units combine a dual vertical PES membrane with a cartridge design that prevents accidental over-concentration, delivering sample recovery above 90%. They run in standard centrifuge tube rotors, so no special hardware is needed.
This listing is for CELLTREAT catalog number 230708, the 4mL Centrifugal Filter Unit, 5kDa MWCO, sold as a full case of 8 (8/Box). Units come in 4mL and 15mL formats with 5, 10, 30, 50 or 100kDa molecular weight cut-offs printed clearly on each cartridge. Polypropylene tubes carry bold black graduations, molded conical-bottom marks for small volumes and a large white writing area, and the flat green HDPE caps have integrated liners for a leak-proof seal. Units are non-sterile, non-pyrogenic and RNase/DNase free, operate from 0°C to 40°C, and are packed 8 per box; each item is sold by the full case. LIGHT LABS keeps CELLTREAT essentials like this ready to ship by the case.
