Maxi-Spins are centrifugal filter devices designed for filtration, concentration, desalting, and deproteinization of small volumes of aqueous and non-aqueous solutions. A Complete device consist of a polypropylene insert that houses a filter membrane and a tapered 50ml reservoir (filtrate) tube (30mm diameter) with hinged cap (fits into standard centrifuges). Solutions to be filtered are placed into the insert which is then placed into the reservoir (50ml tube). Filter size is 19mm diameter. Maximum operating temperature is 50 degrees Celsius. Inserts can accommodate sample volumes up to 25ml. Hold-up to volumes on the membranes are resulting in minimal sample loss. Available in non-sterile only. Maximum centrifugal force is 2,500 x G.
Outside diameter of reservoir tube is 30mm.
All components, except for the filter membrane, are manufactured from high purity polypropylene.
