All Agilent Captiva Premium Syringe Filters are supp…

Fully automatable protein precipitation

Captiva EMR-Lipid provides highly selective, efficient lipid/matrix removal without analyte loss. The novel EMR-Lipid technology removes lipids based on size exclusion and hydrophobic interaction. Effective lipid removal ensures minimal ion suppression of target analytes, significantly improving method reliability and ruggedness.  

Luer lock inlet offers leak-tight syringe connection. Variety of filter types, porosities, and diameters. Color coded for easy identification. Rugged polypropylene housing. Autoclavable to 121 °C for 15 minutes. Quantity break pricing for greater savings.

Use with any standard male luer end SPE cartridges. Inert, PTFE sample guides reduce cross-contamination and carryover. Flexible sample collection rack will accommodate a variety of receiving vessels. Quick vacuum-release valve for better system control. Individual valves allow vacuum control for each cartridge, improving reproducibility.
