Xpress Micro and Mini Dialyzer are highly innovative ready-to-use dialysis devices for small sample volumes. They allow a very fast and efficient purification of protein, RNA and DNA samples. Due to low-binding plastic and small membrane surface area, the device shows excellent sample recovery compared to ultrafiltration and resin systems.

Xpress Micro Dialyzer MD100 is suitable for sample volumes of 10 µl – 100 µl and MD300 for sample volumes of 50 µl – 300 µl.
Xpress Mini Dialyzer are suitable for sample volumes of 150 µl – 1000 µl.

Equilibrium dialysis is ideal for studying the binding of small molecules and ions by macromolecules like in protein-drug or serum-protein binding assays. The design of the Xpress Equilibrium Dialyzer ED300 is optimized for fast and easy equilibrium dialysis.

That's what our customers say:

Michaela Aloe (Pieris Pharmaceuticals GmbH)
"We routinely use Xpress Mini and Micro Dialyzers in our workflow. Xpress Dialyzers are ideal for efficient and fast dialysis of small sample volumes. The handling is very easy and secure, due to sample loading and retrieval with standard micropipettes."

Dr. Martin Haslbeck (Technical University of Munich, Chair of Biotechnology)
"We use the Xpress Micro Dialyzers in our protein lab for small sample volumes. Particularly, we are convinced by the short dialysis time, the easy handling and the secure sample loading and removal without noteworthy loss."
