These 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

Devices are constructed from two sheets of low protein-binding, regenerated cellulose membranes to ensure maximum sample recovery and purity and contain up to 85% less plastic per volume compared to other devices. Slide-A-Lyzer dialysis flasks are compatible with most laboratory buffers and can accomplish low-molecular weight contaminant removal, buffer exchange and desalting in 8 hours to overnight.
