Sartorius Centrisart - beginner kit - 68X51X106

3 each of: 5 kDa MWCO (CTA); 10 kDa MWCO (CTA); 20 kDa MWCO (CTA); and 100 kDa MWCO (PES) Made with cellulose triacetate (CTA) membranes that have high hydrophilicity and very low nonspecific binding Hydrophillic properties with very low non specific protein binding Cast without a membrane support that could bind filtered solutes for use when recovery of filtrate is most important (i.e. free drug or hormone testing) Volume Range of 0.1 to 2.5 ml Separate proteins from low molecular weight substances in biological samples Deproteinate biological samples Reverse centrifugal concentration process prevents premature blockage of the membrane Unique design can be used in fixed-angle or swinging-bucket rotors accepting standard 15 ml tubes Ultrafiltration of 90% of the original sample volume is typically completed in about 30 minutes Ultrafiltrate is collected in the floater insert tube, where it is accessible without removing the tube
