Ultra centrifugal filters provide fast sample processing and promote high sample recoveries, even in dilute samples, through ultrafiltration.

Supplier: Merck

Filters for sterilising or clarifying biological solutions. The larger filtration area increases flow rate and throughput. It also makes it easier to filter solutions because it reduces the pressure required to empty the syringe.

Diethylene glycol for synthesis

Supplier: Merck

These centrifugal filter units can be used for a number of applications: concentration of biological samples containing antigens, antibodies, enzymes, nucleic acids, or microorganisms; purification of macromolecular components found in tissue culture extracts or cell lysates and protein removal prior to HPLS; concentration of dilute or pre-purified proteins from column eluents; desalting, buffer exchange and protein dialysis; size exclusion and protein fractionation.

Supplier: Merck

Ideal for sterilising tissue culture media, buffers, or other aqueous solutions. The no tip, tapered receiver flask and compact profile of the Stericup® design improve stability and make gripping the receiver easier.
