Centrifugal Filters, 2.0 mL, 500 uL, Centrifugal Filters, With 2.0 mL micro centrifuge tube with lid lock, PES membrane, Non Sterile, Molecular Weight Cutoffs 50KDa, 300piece(s)/case

All materials conform to USP Class VI standards. In total,five molecular weight cutoff (MWCO) options are available, meeting the filtration needs for molecules of different sizes; The filter is structurally designed with a high-performance vertical single- (0.5 mL)/double-sided (5 mL & 15 mL) PES filtration membrane, featuring a larger effective filtration area and a higher flow rate; The 5 mL and 15 mL tubes are provided with supports, improving the stability of the structure, supporting a higher centrifugal speed, and reducing the filtration time; Protein recovery is increased to over 80%; There is a printed scale and a white area for writing on the tube, facilitating identification and marking; 100% undergone for production line air tightness test; DNase-free, RNase-free, non-pyrogenic.
