Environmental Express ProWeigh® 55mm TSS Filters (100/Pack)
Streamline Your Suspended Solids Testing
Accelerate your laboratory workflow and eliminate tedious sample preparation with Environmental Express ProWeigh® Filters (Item #: F93455MM). Specifically engineered for busy environmental and analytical lab professionals, these 55 mm filters arrive at your bench pre-treated, pre-weighed, and completely ready for immediate Total Suspended Solids (TSS).
By shifting the time-consuming preparation steps from your analysts to our automated facility, your lab will significantly reduce labor costs, minimize human error, and achieve faster turnaround times.
Engineered for Superior Accuracy and Compliance
Every ProWeigh® filter is fully compliant with Standard Methods 2540 guidelines. Prepared using high-quality binderless borosilicate glass microfiber with a precise 1.5 µm pore size, these filters are designed for ultimate stability and repeatability.
To guarantee the highest data integrity, each filter undergoes a rigorous automated preparation process:
Triple Vacuum Rinsed: Washed three times with reagent-grade water to remove any residual manufacturing impurities.
Oven-Dried & Desiccated: Fully dried and cooled to ensure zero moisture interference.
Robotically Weighed: Weighed by advanced robotics to a tolerance tighter than the Standard Methods requirement of +/- 0.5 mg.
Laser-Cut Precision: Finished with flawless laser-cut edges to eliminate the loose fibers that frequently cause inaccurate weights in standard hand-cut filters.
Smart Data Tracking and Individual Packaging
Say goodbye to messy logging and misplaced weights. Each 55 mm filter is individually packaged in its own protective aluminum dish. The precise initial weight is clearly printed on the dish in both standard text and digital barcode format for seamless integration into your laboratory information management system (LIMS). Complete lot data—including box IDs, weight 1 data, and lot numbers—is available for instant digital download.
