GVS Filter Paper, Disk, 70mm, Ashless-Very Slow, Grade 42, 100/PK FP070DXS42QANC01

Quantitative ashless filter paper in 150 mm disk format designed for very slow flow filtration and critical gravimetric and quantitative analyses. Suitable for Buchner funnels and filtration under pressure, it provides very slow filtration with high retention for extremely difficult filtrations and analytical precipitates such as barium sulphate, metastannic acid and finely precipitated calcium carbonate. The product is intended for laboratory use where low ash content and reliable particulate retention are required.
