Product Description
The Asahipak GFPre-columns or Guard Columns50x7.5mm, 9µm, are used to protect AsahipakGF HPLC and SEC columns are used. As these are prepacked guard columns, no additional holder is required.

Additional Information
The Asahipak product family is primarily based on porous polyvinyl alcohol particles. The hydrophilic polymer backbone is chemically stable and, compared to silica, produces only minimal undesirable interactions with basic compounds or biomolecules. Reverse-phase, HILIC, ion exchange, and size exclusion chromatography are supported through C18, C4, amino, and ion-exchange modifications, as well as defined pore sizes. Same-phase guard columns protect the packing bed from particles and highly retained matrix components.
