Product Description
Quantitative Filter Paper
Product introduction
In the manufacturing process of quantitative Filter Paper, the pulp is treated with hydrochloric acid and hydrofluoric acid and washed with distilled water to remove most of the impurities in the paper fiber. Therefore, the residual ash content after ignition is small, and there is little impact on the analysis results. It is suitable for Precision quantitative analysis. The amount of ash produced after ashing does not exceed 0.0009%.
Our filter paper have 3 type.
high speed filter paper : filter speed ≤ 35 Second
mid speed filter paper : filter speed ≤ 70 S Second
slow speed filter paper : filter speed ≤ 140 S Second

product usage
Quantitative filter paper is mainly used for ashing weighing analysis after filtration, that is, gravimetric analysis test and corresponding analysis test in quantitative chemical analysis. The weight of ash after each filter paper is a fixed value; Qualitative Filter Paper is used in general Filtration, qualitative chemical analysis and corresponding filtration separation. The difference between quantitative filter paper and qualitative filter paper mainly lies in the amount of ash produced after ashing: qualitative filter paper does not exceed 0.13%, and quantitative filter paper does not exceed 0.0009%.
Ashless filter paper It is a quantitative filter paper with an ash content of less than 0.1 mg. This weight is negligible on analytical balances.
