The Centri-Spin 10 Spin Column is a centrifugal device used for the rapid and efficient purification of larger molecules (proteins, nucleic acids, complex carbohydrates, etc.) from small molecules (nucleotides, buffer salts, etc.). It is made of high-quality polypropylene and has a capacity of 10ml. The column is designed to provide excellent recovery of DNA fragments with sizes greater than 10 base pairs or 10-mer, while removing > 98 % of salts, NTP's and other unwanted low-molecular-weight impurities. Each Centri-Spin 10 spin column comes with a specially fritted microfuge tube, dry gel, a wash tube, and a standard plastic bottle cap (pack of 10). It is easy to use and can be used with a variety of sample types, including blood, tissue, and cell culture.
