Vivaspin® Filtrate Concentrator

Vivaspin® Filtrate Concentrator

Up to 2.5 ml starting volume
Concentrate up to 40x

Vivaspin Filtrate centrifugal devices allow concentration of difficult to filter samples, such as whole blood or cell lysates, up to 2.5 ml in volume. They can be used in rotors accepting 15 ml centrifuge tubes. The unique piston design allows ultrafiltration to take place in the direction opposite to the centrifugal force and prevent premature blocking of the membrane. The filtrate is collected in the inserted piston tube which is easily withdrawn to then pipette the concentrate.

  • Concentration of fungal antibodies prior to complement fixation or immunodiffusion for detection of Coccidioides and Aspergillus.
  • Concentrate bacterial antigens (H. influenzae, S. pneumoniae) prior to latex particle agglutination for detection of sepsis in newborns.
  • Protein removal from serum & cell / tissue lysates.
  • Prepare samples for mass spectrometry.
