Slide-A-Lyzer™ MINI Dialysis Devices

Slide-A-Lyzer™ MINI Dialysis Devices have a unique cup-like design and are available in 0.1, 0.5, and 2 mL capacities.

Our MINI dialysis devices come in two formats: 0.1 mL devices, which can be placed into a foam float during dialysis, and 0.5 mL and 2 mL sizes, which are capped by inserting them into the included 15 mL and 50 mL conical tubes, respectively.

The tubes serve as dialysis reservoirs for easy and self-contained dialysis, and are available in 2K, 3.5K, 7K, 10K, and 20K molecular weight cutoffs (MWCOs).

Sample dialysis with a 0.5 mL or 2 mL Thermo Scientific Slide-A-Lyzer MINI Dialysis Device.

High protein recovery is obtained using the 2mL Thermo Scientific Slide-A-Lyzer MINI Dialysis Device.†

Membrane MWCO (K)	Protein/Peptide	Recovery (%)
3.5	Insulin Chain B (3.5 kDa)	90.13
10	Cytochrome C (12.4 kDa)	94.44
20	Myoglobin (17 kDa)	95

† Insulin chain B, cytochrome C and myoglobin (0.25 mg/mL) in either 50mM sodium phosphate, 75 mM NaCl at pH 7.2 or 0.2 M carbonate-bicarbonate buffer at pH 9.4 were dialyzed overnight (17 hours) at 4°C. The amount of protein in the retentate was determined using the Pierce BCA Protein Assay (Product # 23225).
