Centri-Spin™ 10

Centri.Spin™ 10 columns are used for the fast and efficient purification of larger molecules (proteins, nucleic acids, complex carbohydrates etc) from small molecules (nucleotides, buffer salts etc).
The Centri.Spin™ 10 gel will 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. Proteins, peptides, and protein conjugates >= 5 kD can also be efficiently separated/desalted from unwanted low molecular weight impurities.
Each unit consists of a specially fritted microfuge tube, dry gel, a wash tube and a sample collection tube, all specifically designed for this purpose.
The column gel is hydrated with either reagent-grade water or a suitable buffer of your choice, and spun in a microcentrifuge of swinging bucket centrifuge to remove the interstitial fluid. Your sample is then applied to the column and spun again, leaving you not only with a sample purified through the removal of low molecular weight compounds, but also exchanged into the buffer of your choice.
These columns are far superior - easy to use, quick protocol, non toxicity - than phenol/chloroform extraction, ethanol precipitation, dialysis and ultrafiltration.
