Centrifugation is a mechanical process that uses centrifugal force to separate molecules or particles from a solution based on their size, shape, density, average viscosity and rotor speed. It is one of the most important and widely used research methods in biochemistry, cell biology, molecular biology, and nanotechnology. This request is for a replacement of a device that has been in use for more than 10 years by various research groups (Faculty of Bioscience Engineering). This equipment is a refrigerated high-speed centrifuge, used frequently for the purification of plant proteins.  A recent problem was solved, but it is unlikely that repair is possible a next time. This centrifuge needs to be urgently replaced due to the lack of spare parts in the case of a breakdown. This basic equipment is of very great value for all current and future research projects and both the main equipment, and its rotors need to be renewed.
