Dialysis Products

Thermo Scientific dialysis units help facilitate the rapid and trouble-free dialysis of sample volumes from 10 μL to 250 mL. Unlike standard flat tubing, these innovative devices do not require knots or clips that can lead to leaking and sample loss.

Pierce 96-well Microdialysis Plates and Slide-A-Lyzer Dialysis MINI Devices are ideal for small volumes, Slide-A-Lyzer Dialysis Cassettes (original and G2) are recommended for small to medium volumes, and Slide-A-Lyzer Dialysis Flasks are recommended for larger volumes. 

  • Excellent sample recoveries—low-binding plastic and membrane help minimize sample loss compared to filtration and resin systems
  • Convenient—easy-to-grip format helps simplify sample addition and removal with syringe and/or pipette
  • Secure—sealed membranes help prevent leakage that can occur with dialysis tubing and homemade devices
  • Validated—each device is leak-tested during production

2K MWCO

2K_MWCO_graphSample retention by the 2K MWCO Thermo Scientific Slide-A-Lyzer Cassette membrane. Vitamin B12, bacitracin, tyrosine kinase peptide 1, biotin-TPKs substrate, protein kinase Ce (PKCe) peptide substrate, and insulin A chain model systems (0.5-1 mg/mL) in either saline or 0.2 M carbonate bicarbonate buffer, pH 9.4 were dialyzed overnight (17 hours) at 4°C. The amount of retentate was estimated using either the Thermo Scientific Pierce BCA Protein Assay or absorption at 360 nm (for vitamin B12).

3.5K MWCO

3-5K_MWCO_graphSample retention by the 3.5K MWCO Thermo Scientific Slide-A-Lyzer Cassette membrane. Vitamin B12, insulin B chain, and insulin (1 mg/mL) in either saline or 0.2 M carbonate bicarbonate buffer, pH 9.4 were dialyzed overnight (17 hours) at 4°C. The amount of retentate was estimated using either the Pierce BCA Protein Assay or absorption at 360 nm (for vitamin B12).

7K MWCO

7K_MWCO_graphSample retention by the 7K MWCO Thermo Scientific Slide-A-Lyzer Cassette membrane. Vitamin B12, insulin B chain, insulin, and cytochrome C (1 mg/mL) in either 0.15 M sodium chloride or 0.2 M carbonate bicarbonate buffer, pH 9.4 were dialyzed overnight (17 hours) at 4°C. The amount of retentate was estimated using either the Pierce BCA Protein Assay or absorption at 360 nm (for vitamin B12).

10K MWCO

10K_MWCO_graphSample retention by the 10K MWCO Thermo Scientific Slide-A-Lyzer Cassette membrane. Insulin B chain, insulin, and cytochrome C (1 mg/mL) in either 0.15 M sodium chloride or 0.2 M carbonate bicarbonate buffer, pH 9.4 were dialyzed overnight (17 hours) at 4°C. The amount of retentate was estimated using the Pierce BCA Protein Assay.

20K MWCO

20K_MWCO_graphSample retention by the 20K MWCO Thermo Scientific Slide-A-Lyzer Cassette membrane. Insulin B chain, cytochrome C, lysozyme, and myoglobin were dialyzed overnight (17 hours) at 4°C in PBS, pH 7.4. The amount of retentate was estimated using the Pierce BCA Protein Assay.

Thermo Scientific Slide-A-Lyzer Cassettes protect your precious samples during dialysis and help minimize the hassles and risks of losing your samples using slippery tubing. They're available in sizes from 10 µL to 250 mL and in a full range of MWCOs.

 
 
 
Traditional tubingvs.Cassette
Slippery when wet
Flat tubing is difficult to handle when wet, increasing risk of sample loss during sample addition/removal
sample handlingEasy handling and secure sample delivery
Plastic frame and cap allow for secure sample addition/removal
Risk of sample loss
Sample can leak out if clamp becomes loose or falls off
sample recoverySample protection
Welded membrane and leak-proof cap helps minimize the risk of sample loss
Time consuming
Non-optimized design that typically requires overnight dialysis
speedFast and efficient
Innovative design with high surface/volume ratio allows for more rapid dialysis than conventional tubing
