Description
Simpure
filter paper
is composed of cotton fibercellulose filter paper, also known as cellulose filter paper; hydrophilic and absorb little water; the holes in the membrane could pass the  liquid and small particle size solids; and the large particles could not pass, to achieve the Filtration and Seperation.
According to the different manufacturing process, it is divided into
Qualitative
Filter Paper and
Quantitative
Filter Paper; the difference is mainly the weight (amount)  of ash generated after ashing: Qualitative Filter Paper does not exceed 0.13%, and Quantitative Filter Paper does not exceed 0.0009%.

Qualitative
filter paper
Introduction
The
Qualitative
filter paper
can not be soluble in acid, alkali and other organic solvents impure substances, which is applicable to pharmaceutical, chemical plants producing all kinds of pharmaceutical and solvent filtration. The qualitative filter paper is chiefly used for qualitative chemical analysis and relevant filter separation, as well as manufacturing test paper of relevant purity. The good characterization of folded filter paper compared to the same type of filter paper formation has the advantage of speeding up the flow rate and increasing the load power.
Features
High quality and Brand new
Made of 100% alpha cotton cellulose; Ash content 0.1%
Stable from pH 0 ~ 12; thermostable up to 120°C
Not melting in acid, alkali and other organic solvents impure substances
Qualitative analytical techniques to determine and identify materials.
Application:
Moisture absorption
Liquid clarifications, analytical separations
Air and water analysis.
Rough sample preparation
Widely used in general laboratory filtration
- Used in conjunction with laboratory holders and funnels, or with paper cones and funnels.
Areas of use include the food industry, agriculture, air pollution monitoring, and etc.
Widely used in education for teaching simple qualitative analytical separations

Quantitative Ash less Filter Paper
Introduction

®
Quantitative
filter paper is mainly used for quantitative chemical analysis of the gravimetric analysis of the pilot trial and relevant analysis experiment. The filter paper can be applied to scientific research, industry, agriculture, health, tertiary institutions, teaching experiments, environmental protection test, etc.
In the manufacturing process of Quantitative Filter Paper, the paper pulp has been treated by HCl (Hydrochloric Acid) and HF (Hydrofluoric Acid), and washed with distilled water to remove most of the impurities in the paper fiber, therefore, there has little residual ash after burning. So, Quantitative Filter Paper has little effect on the analysis result,  suit for precision quantitative analysis. The amount of ash produced after ashing does not exceed 0.0009%.
The
Qualitative filter paper can be divided into fast, medium speed and slow three categories when measured by filtering speed and separation performance. Quantitative filter paper has the round size that is similar to qualitative filter paper.
Feature
High quality and Brand new
Also called "ash-free filter paper"
Made of Highest quality alpha cotton cellulose; "Ashless" (Ash content 0.01%)
Acid washed and rinsed with ultrapure water to neutralize
Round size
Application
Used for quantitative and gravimetric analysis.
Quantitative filter papers are the choice for gravimetric analysis.
High purity hardened filters have a high wet-strength and are chemical resistant to handle vacuum filtration or acid/alkali solutions.
Qualitative filter papers are used for liquid clarifications
Analytical separations, or air and water analysis.
Weighing -used with Balance
Note
:
The filter paper is best not to filter hot concentrated H₂SO₄ (Sulfuric acid) or HNO3 (Nitric acid ) solutions.
