Acid Washed TCLP Filters

Environmental Express is proud to offer the only TCLP filters that meet all guidelines for acid washing as set forth in EPA Method 1311. These filters are washed in 1N HNO3 acid and then rinsed three times with copious amounts of deionized water. Each rinse uses more than one liter of deionized water per filter. The filters are oven dried at 105°C prior to final conversion. The use of prewashed filters saves reagent cost and reduces chemical waste in your laboratory. Filters are washed, rinsed and dried in a consistent procedure which may reduce blank variability and typically provides lower background metals levels than are achieved with on-site filter preparation.
Each box of prewashed TCLP filters is supplied with an independent certification of preparation warranting that the filters were prepared by Method 1311 protocols. The certificate also gives demonstrated background TCLP metals levels. LE1002 - TCLP RotatorZHE1000PF000-2 - Maxfil Filtration SystemAcid-Washed TCLP FiltersStandard TCLP FiltersLearn More about Try Something New

Question/Answer

acid washed prefilters for syringe filters??

We do not offer acid washed prefilters for syringe filters. However, we do have acid washed glass fiber filters which are 25 mm with a 0.7 um pore size (part SF1070G).

Can paper filters be used in the Maxfil?

The Maxfil can be used with any type of filter.

Do FG75142MM TCLP Filters have a Certificate of Analysis available?

The FG75... filters do not come with C of A\'s as they are not acid-washed or tested for background metals. Only the FG77... filters are and will come with the appropriate C of A.
