Nucleic acid concentration and rebuffering with centrifugal ultrafilters is a fast, high yield and reproducible alternative to percipitation. PCR grade (ETO sterilsed) devices allow safe use in PCR applications, even in the highly contamination sensitive forensic industry. The DNA ultrafiltration devices are available with 500 µl and 2 ml volume capacity. The Hydrosart® membrane stands for high nucleic acid recoveries...

Ultrafiltration is a safe and non-denaturing method for the protein concentration and sample concentration, as well as their desalting and buffer exchange. Process alternatives range from centrifugal concentration for samples up to 100 ml, to pressurised cells for samples up to 250 ml and cross flow (tangential flow) filtration for samples up to 5 l. A wide choice of membrane cut offs and membrane materials (PES,...

Fractionation is a frequent need when working with biological samples. Utilising ultrafiltration devices with horizontal membranes allows fast and easy fractionation when the agents to be separated differ by a factor 10 in size. For applications like primer removal after PCR reactions, or pepdtide removal, two centrifugal devices for fractionation are offered with 500 µl and 2 ml volume capacity and a choice of...
