The Ultra-Micro DispoDialyzer is a disposable dialyzer for the processing of extremely small samples from 1 µl to 5 µl. Dialysis is carried out inside a micro centrifuge tube.

Membrane options are available with molecular weight cut offs from 1,000 to 50,000 Daltons. Ultra-Micro DispoDialyzer includes two 1.5 ml capped micro centrifuge collection tubes.

Sample recovery is easy with almost 100% sample recovery. Once dialysis is complete, either extract your sample with a pipette, or invert the dialyzer into a new collection tube and briefly centrifuge (500 to 2000 rpm for 1-2 seconds).

Key Features:

  • Micro-volume dialysis
  • Easy to use
  • Low protein binding
  • High sample recovery
  • Rapid dialysis/purification

  Applications: 

  • Exchange of buffers
  • Removal of detergents
  • Concentration of samples
  • HPLC, HPCE
  • Purification of proteins, DNA and RNA
  • Removal of excess radiolabel or PCR-primers
  • GC, GC-MS, NMR
