Thermo Scientific™ Slide-A-Lyzer MINI Dialysis Devices, 3.5K MWCO are disposable polypropylene cups with integrated, low-binding membranes for dialysis and high recovery of proteins and macromolecules >3.5 kDa in volumes from 10μL to 2mL.

These 3.5K MWCO dialysis devices are available in three sizes (0.1, 0.5 and 2mL capacities), and are designed to allow easy sample addition and removal using a standard laboratory pipette. The MINI Devices are effective and convenient for accomplishing typical sample desalting or buffer exchange in 4 to 8 hours. 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.


Three convenient sizes – dialysis devices for 0.1, 0.5 and 2mL samples fit standard 1.5mL-microcentrifuge, 15mL- and 50mL-conical tubes, respectively

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

One-step protocol – pipette sample into the MINI Device and place in tube containing the dialysis buffer; no laborious assembly, device preparation or expensive equipment are required

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
