Whatman filter papers are made from high-quality materials and are used in a variety of applications, including qualitative and quantitative analysis. They are available in different grades, each with specific properties and uses:

Grade 1A medium flow filter paper with medium retention. It's commonly used for clarifying liquids, soil analysis, seed testing, and separating solid foodstuffs from liquids.
Grade 542A fine filter paper made from cotton linters with a nominal particle retention rating of 2.7 m. It's used for capturing fine precipitates, collecting trace elements and radionuclides, and gravimetric metal determinations.
Quartz fiberA high-purity quartz microfiber filter used for air sampling, particularly at high temperatures. It's used for PM2.5/PM10 and trace element analysis.

Whatman filter papers are categorized by grades based on various properties, including thickness, weight, and particle retention. The most common qualitative paper grades are 1-6, 595, 597, 598, and 602.

FAQ's of Whatman Filter Paper 127MM Grade 40:

Q: How is Whatman Filter Paper 127MM Grade 40 typically used in laboratory applications?

A: It is widely employed in gravimetric and quantitative analytical processes that require precise residue measurement. Its slow filtration speed and fine particle retention of 8 m make it ideal for separating fine particulates in chemical analysis.

Q: What are the benefits of using Grade 40 filter paper with less than 0.007% ash content?

A: The exceptionally low ash content ensures that the filter paper leaves minimal residue after incineration, which is crucial for highly accurate quantitative analysis, especially in determining ash measurements of samples.

Q: When is it recommended to select Grade 40 filter paper over other grades?

A: Grade 40 is recommended when performing tasks that demand quantitative results with fine particle retention and slow filtration, such as precise lead sulfate or barium sulfate separations in laboratory settings.

Q: Where can I purchase authentic Whatman Filter Paper 127MM Grade 40 in India?

A: You can obtain this product through authorized distributors, exporters, manufacturers, and suppliers, who cater to research institutes, laboratories, and industrial clients across India.

Q: What is the process for using this filter paper in sample filtration?

A: Place a 127 mm Grade 40 circle into the appropriate filter setup. Pour the sample evenly to allow slow and efficient filtration, ensuring optimal particle retention and minimal material loss.

Q: Why is slow filtration speed advantageous in quantitative analysis?

A: A slower filtration speed allows for more thorough separation of fine particles, reducing the risk of blockage and ensuring consistent results in gravimetric determinations.
