As specified in EPA Method 1664B, Xenosep® High Performance (HP) Solid Phase Extraction (SPE) filters for EPA Method 1664A/B-HP are designed to provide high recovery and low blank values in Horizon® SPE-DEX® and SPE manifold EPA Method 1664A applications. Each SPE filter consists of…

Xenomax® Pre-Weighed TSS Filters are pre-washed, predried, pre-desiccated, and pre-weighed in accordance with Standard Methods 2540 D and are ready to use out of the box. To significantly speed up TSS analysis, simply filter your sample, dry the filter, and record its final weight. These…

ValuSep® transfer pipets help enable easy transfer of the extract to the aluminum panand also the rinse down of manifold glassware with the smallest solvent volume possible during the optional trasfer of solvent from the bottle rinse to the SPE funnel rinse.

ValuSep® 5um Glass Micro Fiber (GMF) prefilters are made of two separate layers of glass fiber in a very thin format for highly efficient capture and retention of particles that could prematurely clog an SPE filter.

ValuSep® 5um Polypropylene (PP) prefilters are very open and thick, hydrophobic prefilters made of polypropylene fibers. They protect the SPE filter from premature clogging due to particulate ladden wastewaters.

ValuSep® Solid Phase Extraction (SPE) filters for EPA Method 1664A are designed to provide high recovery and low blank values in Horizon® SPE-DEX® and SPE manifold EPA Method 1664A applications. Each SPE filter consists of glass fibers which have been chemically modified so they retain…

Binder-free, fast flowing, fine porosity borosilicate glass microfiber filters have been optimized for better wet strength/handleability and high temperature (550°C) blank stability; two quality issues known to affect other brands of TSS filters. Xenomax TSSFVS Filters are readily available in…

ValuSep® Precision and Recovery (PAR) Standard for EPA Method 1664A is premade and ready to use. Simply aliquot enough volume to achieve a final concentration of 40mg/L (i.e., either 10mL @ 4mg/mL or 5mL @ 8mg/mL).

ValuSep® aluminum pans are made of smooth wall construction to help prevent the analytes from creeping or wicking out of the pan during the evaporation process. The larger diameter of the 105mm pans enables fast drying of extracts up to 125ml while almost twice as many extracts up to 55mL can be…
