Lab filter paper is often used in routine filtration, and this 11μm filter paper has a medium retention capacity and flow rate. The specifications range from 10mm to 500mm discs, and 460*570mm rectangles. Lab filter paper can also be used on filter cups.

This qualitative filter paper covers most laboratory applications and is often used for liquid clarification. Laboratory filter paper is also traditionally used for qualitative analysis of precipitates, such as lead sulfate and calcium oxalate.

Description of Laboratory Filter Paper Grade 1

Moderate retention and flow rate are most frequently used in 11 μm daily filtration. It is widely used in laboratory applications to clarify liquids. It is used for the quantitative analysis and separation of precipitates, such as lead sulfate, calcium oxalate, and calcium carbonate.

Advantage of Laboratory Filter Paper Grade 1

• All the filter paper passed the ISO9001 & CE certificate;
• High purity and good performance to give you a faithful experiment;
• The lowest ashless ensures the result of testing;
• Full range of diameter provided, customized allowed;
• Whatman Grade 1 equivalent quality but lower price;
• Easy to use for pre-cut filter paper.

Features

1. The same quality and specification as to Whatman Grade 1;
2. Medium retention with pore size 11μm;
3. The common diameter and OEM size are accepted;
4. Small orders and free samples can be accepted.

Applications

• In the agriculture field, it is used for soil analysis and seed testing.
• In the food field, it is commonly used to separate solid foods from related liquids and liquids
• It is also widely used in teaching simple qualitative analysis separation.
• It also can use for air pollution monitoring
• It also can test the gas after soaking with reagents
