Environmental Express ProWeigh® VSS Filters | 47 mm, 1.5 µm (100/Pack)
Streamline Your Suspended Solids Testing
Accelerate your laboratory workflow and eliminate tedious sample preparation with Environmental Express ProWeigh® Volatile Suspended Solids (VSS) Filters. Designed specifically for busy environmental and analytical chemistry labs, these ready-to-use filters allow lab professionals to bypass time-consuming washing, drying, and weighing steps, moving straight from filtration to final analysis.
Uncompromising Accuracy & Compliance
Engineered to meet rigorous regulatory standards, ProWeigh® filters are fully compliant with Standard Methods 2540. Each filter is processed under strict quality control guidelines to deliver precision that exceeds standard requirements:
Laser-Cut Precision: Advanced laser-cutting guarantees clean edges, eliminating loose fibers and preventing the inaccurate weight fluctuations common with traditional hand-cut or punched filters.
Tighter Tolerances: Our automated robotic weighing process demands a mass tolerance tighter than the Standard Methods requirement of $\pm0.5 \text{ mg}$, ensuring unparalleled repeatability.
Pre-Prepped Stability: Every filter undergoes a rigorous treatment cycle—vacuum-rinsed three times with reagent-grade water, dried, cooled, and desiccated—to ensure immediate stability out of the box.
Smart Data Management
Each filter is individually prepared and placed into its own aluminum dish. For seamless sample tracking and data integrity, the precise initial weight is printed directly on the dish in both standard text and barcode formats. Additionally, lab professionals can easily access and download comprehensive lot data, including box IDs, initial weights, and lot numbers, for effortless digital archiving.
