Reusable Dialysers

BioDialyzer^TM

A simple device for dialysis of samples from 10 µl to 5 ml. Place the sample in the Teflon chamber, add a pre-cut membrane and the Teflon cap, and place the whole unit in a beaker of dialysis buffer. Simple and easy dialysis for:

• Purification of biomolecules
• Exchange of buffers
• Removal of detergents
• Sample concentration
• HPLC, HPCE
• Removal of excess radiolabel
• Post-PCR clean-up
• GC, GC-MS, NMR

Fast, simple, easy to use - here's a diagram of the steps

BioDialyzer Turbo^TM

The BioDialyzer Turbo is similar to the original BioDialyzer, but has two ports and hence two membranes, one on each side of the sample. So it's twice as fast!

• Twice as quick
• Reusable
• Available for most sample sizes - large or small
• Membranes available with MWCOs to suit almost any application
• Easy to use
• Leak-proof
• Autoclaveable
• Low protein binding
• High sample recovery
• Rapid dialysis/purification
• Made of Teflon - totally inert

SpinDialyzer^TM

The SpinDialyzer has a built-in magnet that allows the entire unit to be rotated during dialysis, using a magnetic stir plate. This significantly speeds up dialysis. Both standard and Turbo (two ports & two membranes) are available. We can also supply suitable stirrer plates.

• Exchange of buffers
• Removal of detergents
• Concentration of samples
• HPLC, HPCE
• Immunoblotting*
• Purification of proteins, DNA and RNA
• Removal of excess radiolabel
• Post-PCR clean-up
• GC, GC-MS, NMR
• Removal of CsCl, agarose, pyridoxal-5-phosphate*
• Removal of silicates after chromatography*
• Complex carbohydrate purification*
• Equilibrium dialysis
• Protein binding assays
