Environmental Express ProWeigh Filters for Volatiles 47mm 100pk

ProWeigh® filters from Environmental Express are a time-saving, convenient and accurate way to perform Total Suspended Solids. By eliminating all the required filter preparation steps necessary for solids determination, the hands-on time required for performing TSS is reduced by half.

The 20th edition of Standard Methods, the definitive book of water and wastewater test methods, lists ProWeighs from Environmental Express by name. Method 2540C, Total Dissolved Solids Dried at 180°C; Method 2540D, Total Suspended Solids Dried at 103-105°C; and Method 2540E, Fixed and Volatile Solids Ignited at 550°C all specifically list ProWeighs as an acceptable filter. ProWeighs were approved for use by the Standard Methods committee in 1997. To use ProWeighs, simply remove one from its pan, place it on a filter funnel and filter your sample. After filtration is complete place the ProWeigh filter back in its pan and dry in an oven for the final weight determination. All the washing, drying and preweighing is done for you.
