RFQ - BioCentrifuge and Rotors 129563

Tender description

The National Physical Laboratory [NPL] requirement is for a floor-standing centrifuge with a set of compatible rotors to be used for biological applications. The purpose is to perform key steps in cell culturing, protein production and DNA purification. These include, for example, collecting bacterial and mammalian cells from large-scale cell cultures, separation of cell debris from the soluble fraction of cell lysate, pelleting of DNA precipitate and removal of excess liquids in centrifugal and binding columns for protein and DNA purification. The centrifuge needs to be a floor-standing, bio-safe, temperature controlled, and compatible with all selected rotors. The centrifuge must be able to accommodate a range of volumes, up to 6 litres, and run with a variety speeds, up to at least 75,000 relative centrifugal force, when used with suitable rotors. The set of rotors must cover the required speeds, volumes, and bottle/tube requirements.
