MINI Dialysis Units - below 2K MWCO? (Jan/28/2011 )


I would like to find any Dialysis Units (bags, casettes, etc.) below 2K MWCO. So far I found only Slide-A-Lyzer MINI Dialysis Units from Pierce with 2K cutoff ( but i need something below this limit. The reason is because i want to desalt my RNA oligomer after several erlier steps.




you can find spectra/por dialysis membranes with mwco as low as 500 Da.

you can find it at thomas scientific and spectrum and thermofisher.
