GE Healthcare offers an extensive range of syringe filters and syringeless filters. Our syringe filters come in different diameters, pore sizes, and membrane types. Choose between sterile or nonsterile versions with or without prefilters. Our syringeless filters include Mini-UniPrep filter vials that function as both filter and HPLC autosampler vials, UniPrep which is a combined filter and storage vial, and Autovial which is an integrated filter and syringe.Syringe filters and syringeless filters are primary choices for analytical sample filtration. Syringe filters are syringe-coupled filters, while syringeless filters are self-contained filter devices that do not require a syringe. Choosing the correct type of filter device for your application allows you to speed up and simplify your filtration step.
