The ultrafiltration centrifugal tube is also called centrifugal filter unit disposable which is a single-use ultrafiltration device with membrane inside for the concentration and/or purification of biological samples. The optimized design with twin membrane filters and sleek internal profile ensure maximum process speeds all the way down to the last few microliters, which results in more than 80-fold concentration. The innovative design, ease of use, speed and exceptional concentrate recoveries are the main features of the concentrators. This 15/50 ultra centrifugal filter unit including concentrator insert(with membrane inside), outer tube and cap enables the fastest sample concentration with the highest recoveries. This device can handle a sample volume of up to 15 ml in swing-bucket rotors and of up to 11 ml in fixed-angle rotors that accept 50 ml centrifuge tubes.
Application
- Concentration of biological samples containing antigens, antibodies, enzymes, nucleic acids, or microorganisms
- Purification of macromolecular components found in tissue culture extracts or cell lysates and protein removal prior to HPLS
- Concentration of dilute or pre-purified proteins from column eluents
- Desalting, buffer exchange and protein dialysis
