Vivaspin® 4 Centrifugal Concentrator
Up to 4 ml starting volume
Concentrate up to 200x
Vivaspin® 4 ml concentrators are disposable ultrafiltration devices for the concentration of biological samples. Maximum initial sample volumes range up to 4 ml. They can be effectively used in either swing bucket or fixed angle rotors accepting 15 ml centrifuge tubes.
The patented vertical membrane design and thin channel filtration chamber (US 5,647,990) minimises membrane fouling and provides high speed concentrations, even with particle laden solutions.
Vivaspin® 4 is available with the high flux polyethersulfone membrane range which is recommended for most solutions.
Applications
- Concentration of urine prior to electrophoresis for diagnosis of multiple myeloma and amyloidosis.
- Concentrate spinal fluid prior to electrophoresis for diagnosis of meningitis and multiple sclerosis.
- Protein removal from serum & cell / tissue lysates.
- Exchange buffers for proteomic peptide samples.
- Prepare samples for mass spectrometry.
