MD1000 Xpress Mini Dialyzer

MD1000 Xpress Mini Dialyzer

150-1000 µl sample volumes

The Xpress MD1000 Mini Dialyzer is designed for processing large quantities of samples for fast and efficient purification of protein, RNA and DNA samples. The MD1000 is delivered ready-to-use in a 48 deep well plate with 8 sample cartridges where each cartridge has 6 single sample segments. The segments can also be easily separated to test single samples. The patented design of the MD1000 allows 48 samples and dialysate buffers to be loaded and removed from the top of the device without removing the cartridges. The MD1000 may be used with common single and multi-channel pipettes as well as automated liquid handling systems. It is compatible with the SBS microplate standard.

Protein binding studies for the development of active biopharmaceutical products can be easily performed with the MD1000. Clinical diagnostic labs can prepare samples for testing of free hormones such as testosterone, cortisol, FT3 and FT4. Other Xpress Dialyzers are available for a variety of sample volumes with several membrane choices.
