General description

The Pur-A-Lyzer Dialysis Kits are an innovative dialysis tubing that can be conveniently loaded and unloaded using any standard pipette tip while still allowing for 98% sample recovery yield. The revolutionary design of the Pur-A-Lyzer Tube makes it the only dialysis tool which enables true high throughput dialysis, accommodating a large number of samples in a single buffer tank.

The Pur-A-Lyzer Dialysis Tube allows rapid, high performance extraction of macromolecules without contamination. It is ideal for purification of proteins, automated protein sequencing, peptide mapping and amino acid analysis.


  • Dialysis or buffer exchange of volumes between 10 mL and 20 mL
  • Preparation of protein samples for MALDI-MS
  • Sample concentration
  • Large-scale protein dialysis such as antibodies and recombinant protein purification
  • Peptide dialysis for molecules as small as 10 amino acids
  • Virus-particle purification
  • Removal of contaminating micro molecules
  • Purification of tissue culture extracts
  • Removal of salts, surfactants, solvents and detergents
  • Complex formation studies (protein-protein, protein-DNA and protein-RNA)
  • pH and buffer adjustment of sample solution, protein extract or cell extract
  • High through- put dialysis, a single beaker can be used for several Pur-A-Lyzer tubes on one floating pad

For your convenience the Pur-A-Lyzer kits come in four sizes:
Mini: 10-250 μL
Midi: 50-800 μL
Maxi: 0.1-3 mL
Mega: 3-20 mL
