• Qualitative Filter Paper, Medium, 8 um, 125mm, 100 pcs per pack Use qualitative filter papers for analytical methods which identify or determine the constituents of a mixture irrespective of the amount of material present.
• Qualitative filter paper with a diameter of 125 mm is used in various laboratory and industrial applications for filtering liquids and solids.

Features:

1. Diameter and Size:

125 mm Diameter - This size is suitable for small to medium filtration tasks. The 125 mm diameter allows it to fit into various funnel sizes and filtration apparatus.

2. Material:

Cellulose or Synthetic Fibers - Most filter papers are made from high-quality cellulose, but some are made from synthetic materials to suit specific needs. Cellulose filter paper is commonly used for general-purpose filtration, while synthetic options may offer higher resistance to chemicals or heat.

3. Porosity and Filtration Quality:

Grades and Types - Filter papers come in different grades depending on their porosity and the particle size they can effectively filter. Common grades include coarse, medium, and fine, as well as specialized types like quantitative or qualitative.

Retention Rate - The filter paper’s ability to retain particles of specific sizes depends on its grade. Fine grades have a higher retention rate for smaller particles.

4. Applications:

General Filtration - Suitable for separating solids from liquids in various laboratory processes.

Precipitate Analysis - Useful in analytical chemistry for filtering precipitates.

Sample Preparation - Used in preparation of samples for further analysis or testing.

5. Chemical and Temperature Resistance

Chemical Compatibility - Some filter papers are designed to be resistant to certain chemicals, making them suitable for specific applications.
