DIALYSIS / DESALTING

MicroDialyzers

 

 

For Rapid Dialysis of Micro-Volume Samples

Scientists around the world have relied on Spectra/Por dialysis membranes for removing salt and other impurities from sample solutions. Spectra/Por MicroDialyzers offer a wide range of features to enhance conventional dialysis methods of micro volumes. MicroDialyzer units are capable of achieving dialysis equilibrium overnight with maximum sample recovery of protein.Click to enlarge

The Spectra/Por MicroDialyzers are excellent for simultaneous micro sample applications of 24 to 620 無. Each unit is designed to increase dialysis efficiency and maximize sample recovery. Speed and precise control of the dialysis process are the key features of these systems.

Similar to conventional methods, the Spectra/Por MicroDialyzers function by separating the sample to be dialyzed from the buffer by a semi-permeable membrane. Only those molecules larger than the pore size of the membranes will be retained by the membranes. Framed membranes are available to accommodate all sizes of MicroDialyzers in MWCO ranging from 100 to 500k daltons.

Features:

  • Maximum concentration differential due to continuous dialysis buffer exchange

  • Easy-to-use snap clamps to prevent leakage

  • Compatibility with multichannel pipettors for quick and precise sample handling

  • Negligible sample loss and dilution effects due to small membrane surface area

  • Units completely disassembly for easy cleaning

  • Precut, framed Spectra/Por membranes are available for all systems

  • Labeled wells for easy sample identification
