Environmental Express Washed and Dried TSS/VSS Glass Fiber Filters

• Use in Standard Methods 2540
• Provide consistently stable weights
• Made from binderless borosilicate glass and have a 1.5 µm pore size

Laser cutting ensures a clean, sealed, fiber-free edge that maintains its integrity throughout washing and drying, as well as your testing process. These filters are rinsed three times with DI water to ensure they are fiber free. TSS filters are then dried in an oven at 105°C to obtain stable weights. VSS filters are dried at 550°C to ensure all volatiles are removed.
