Pierce™ Slide-A-Lyzer™ Dialysis Flasks facilitate simple and effective removal of buffer salts and small contaminants from proteins and other macromolecules in sample volumes up to 250 ml.

• Easy to use
• Color-coded for easy identification
• No leakage, sample remains intact with no contamination
• High surface area to volume ratio maximizes diffusion rate

Slide-A-Lyzer™ Dialysis Flasks are constructed from two sheets of low-binding, regenerated-cellulose dialysis membrane that are hermetically sealed on either side of an inert plastic body.

With Slide-A-Lyzer Dialysis Flasks, typical low-molecular weight contaminant removal, buffer exchange and desalting can be accomplished in 8 hours to overnight.

The membrane and flask materials are compatible with most laboratory buffers.
