LARK® Quantitative Filter Paper, Ashless, Grade 41

GRADE 41 ASHLESS HARDENED

The typical grade for quantitative tasks, is coarser precipitates, such as lead-, iron, and silver sulfide alkali carbonates, foodstuff, and soil analysis. Filtration Speed Fast, Retention – coarse and gelatinous precipitates retains particles >15 µm, filters hydroxides and metallic aerosols, used in environmental monitoring, determining\silica content in steel.
