Whatman™ SPARTAN™ HPLC Certified Syringe Filters
Whatman® SPARTAN™ syringe filters ensure reproducible results from the filtration of organic and aqueous solutions in HPLC. For batch-to-batch consistency, the SPARTAN™ line of syringe filters are tested and certified for the absence of UV-absorbing substances at wavelengths of 210 and 254nm with water, methanol and acetonitrile.
SPARTAN™ syringe filters are ready-to-use filter units with a hydrophilic, low protein-binding membrane made of regenerated cellulose. Excellent chemical resistance against the standard aqueous and organic HPLC solvents. Smaller sized syringe filters are available in both standard form with 13mm diameter or with Mini-Tip form with 13mm diameter. Both styles offer extremely low dead volume of less than 10µL. These are the ideal size of syringe filters for filtration into very small sample bottles and vials. Syringe filters are also an excellent choice for filtration of proteinaceous aqueous solutions. Larger 30mm sizes are also available for larger sized sample filtration.
