General description
Pur-A-Lyzer dialysis tube kits are easy-to-use devices in a screw-cap tube format and are disposable. They contain a dual dialysis membrane window for buffer exchange. Samples are added and removed using a standard laboratory pipette and come in 4 different versions to accommodate a range of sample volumes.
- High sample recovery >97%
- Protease-, RNase-, and DNase-free
- Convenient sample loading- no syringes necessary
- Versatile- dialyze proteins, RNA, and DNA
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.

Application
- 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

What does the volume 50-800ul mean? why is the range so wide? Is the volume of the tube fixed? Does a kit equal to 5 such devices？
1 answer-
The Midi tube capacity is 50-800 microliters. This means that the sample volume should be in the range of 50-800 microliters. The volume of the tube is fixed. Each kit includes a floating rack along with the Pur-A-Lyzer tubes (PURNR-1EA). In the case of PURD10005, this includes 5 tubes with MWCO of 1 kDa.

Can use for dialysis tube for MWCO 323-982 Da?
1 answer-
The product has a capacity of 50-800 μL and an MWCO of 1 kDa. Currently, there is no dialysis or centrifugal device available that would be appropriate for the specific range of 323-982 Da.
