Vivaspin® 4 Centrifugal Concentrator

Vivaspin® 4 Centrifugal Concentrator

Up to 4 ml starting volume
Concentrate up to 200x

Vivaspin 4 centrifugal devices allow rapid concentration of clinical samples up to 4 ml in volume and are intended for in vitro diagnostic (IVD) applications. The patented vertical membrane design minimizes filter fouling and the built in dead stop pocket provides maximum concentrate recovery. Vivaspin 4 devices have been used extensively to concentrate urine samples prior to gel and immunofixation electrophoresis for diagnosis of multiple myeloma, light chain amyloidosis and related blood disorders.

  • 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.
