Filters for TSS or VSS. Filters are composed of binderless borosilicate glass, have 1.5 µm porosity, and are processed thoroughly so you can start testing right out of the box! These TSS filters are vacuum rinsed three times with reagent grade water, dried, cooled, and desiccated to assure the best stability and repeatability. Filters are robotically weighed and placed in individual aluminum dishes where the weight is then listed in print and barcode format. Our standards demand better than the Standard Methods required tolerance of ±0.5 mg. These filters will reduce labor costs, improve accuracy, and provide quicker reporting times for your lab—all you need to do is filter your sample, dry it, and take the final weight! Now you can access and download complete data for all ProWeigh filters. Data includes box ID, weight 1, and lot number. 3 month warranty Decrease sample prep time for your suspended solids testing
