Product Description

Quantitative filter paper
New Star Quantitative Filter Paper is made from the highest quality commodity cotton pulp as raw material, using advanced production and post-treatment processes to refine it; After burning, there is very little residual ash, which has almost no impact on the analysis results and is suitable for precision quantitative analysis. After years of production practice and technical research, New Star Quantitative Filter Paper has formed a stable and reliable production process and inspection system to ensure product quality.
application area
1. Precision quantitative analysis;
2. Liquid purification;
3. Analyze separation or air and water analysis.
