Puradisc™ Aqua 30 syringe filters are specifically designed for environmental sample filtration prior to dissolved organic carbon (DOC) and chemical oxygen demand (COD) analysis.

• From the Puradisc FP 30 range
• Low protein binding, hydrophilic cellulose acetate syringe filter media
• Prewashed cellulose acetate (CA) syringe filter for reduced organic carbon extractables
• Designed for sample preparation in support of dissolved organic carbon and chemical oxygen demand analysis
• Standard inlet and outlet luer connectors

DOC (dissolved organic carbon) and COD (chemical oxygen demand) analysis are common methods to determine organic pollutant levels.

Precisely filtering a sample is a crucial step in DOC and COD, and the quality of the syringe filter should preserve sample integrity. Puradisc™ Aqua 30 syringe filters come prewashed, designed to minimize carbon leaching from the cellulose acetate membrane that could otherwise lead to sample contamination.
