Thermo Scientific Slide-A-Lyzer MINI Dialysis Devices, 7K MWCO are disposable polypropylene cups with integrated, low-binding membranes for dialysis and high recovery of proteins and macromolecules >7kDa in volumes from 10 to 100μL.

Slide-A-Lyzer MINI Dialysis Devices allow easy sample addition and removal using a standard laboratory pipette and can be used for single or arrays of samples. Unlike other small sample separation devices, there is no equipment to assemble, no need for syringe adapters and no laborious steps necessary to manipulate the small volume sample. The regenerated cellulose membrane is compatible with a number of common chemicals and buffers.


  • Flexible format – enables user to dialyze a single sample (tube) or multiple samples (25 array)

  • Excellent sample recoveries – low-binding plastic and small membrane surface area minimize sample loss compared to filtration and resin systems

  • One-step protocol – does not require laborious procedures or expensive equipment

  • 100% leak-tested – innovative design does not permit wicking that can occur in homemade devices

  • Time savings – performs desalting of nucleic acids and proteins (>95% recovery) in less than 15 minutes, which improves sample resolution, quantification and conjugation
