Whatman Grade 1 Qualitative Filter Papers are the most widely used filter paper for routine laboratory applications, qualitative analytical separations, and clarifying liquids. They are the standard grade cellulose filter papers for medium flow rates.

Qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate
Agricultural soil analysis and seed testing procedures
Industrial food processing techniques to extract liquid or separate solid foodstuffs from associated liquid
Air pollution monitoring by collecting atmospheric dust from airflow and photometrically measuring the stain-intensity
Gas detection by quantitative chromogenesis with optical reflectance

Grade 1: 11 m (medium flow filter paper)

The most widely used filter paper for routine applications with medium retention and flow rate
Extended range of sizes includes 10 to 500 mm diameter circles and 460 x 570 mm sheets.

Laboratory Application

This grade is frequently used for clarifying liquids. Traditionally the grade is used in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate.

Agricultural and Food Industry Application

Grade 1 is used for numerous routine techniques to separate solid foodstuffs from associated liquid or extracting liquid and is widely used in education for teaching simple qualitative analytical separations.

Air Pollution Monitoring

Using circles or rolls, atmospheric dust is collected from airflow and the stain-intensity measured photometrically.

For gas detection, the paper is impregnated with a chromogenic reagent and color formation quantified by optical reflectance.

Reliable Qualitative Filtration

Engineered for efficient routine laboratory work, Whatman Grade 1 filter paper provides consistent medium filtration speed, ensuring quick yet thorough separation for qualitative analysis. Its 11 m particle retention capability captures a broad range of particulate matter, supporting diverse filtration requirements. Laboratories benefit from its dependable performance and adaptability.

Broad Applications in Laboratories

Ideal for standard laboratory procedures, this 185 mm circular filter paper accommodates large-volume filtrations without frequent replacement. Its smooth surface texture minimizes absorption of analytes, delivering cleaner separation and precise results. This product is a preferred choice in educational, research, and industrial settings across India.

FAQ's of Whatman Grade 1 Qualitative Filter Paper Standard 185 mm Circle 100 pack 1001-185:

Q: How do I use Whatman Grade 1 Qualitative Filter Paper (Catalog No. 1001-185) in laboratory filtration?

A: To use Whatman Grade 1 filter paper, place a sheet into a suitable filtration apparatus such as a funnel. Pour your mixture onto the filter. The medium filtration speed and 11 m particle retention will separate solids from liquids efficiently, making it ideal for routine qualitative analyses.

Q: What applications are most suitable for the 185 mm diameter filter paper?

A: This 185 mm filter paper suits tasks requiring filtration of large sample volumes, such as gravimetric analysis, soil testing, and general laboratory filtration. Its size reduces the need to replace filters frequently, streamlining workflow in academic, research, or industrial labs.

Q: When should I select Whatman Grade 1 filter paper over other grades?

A: Choose Grade 1 when you need medium filtration speed and moderate fine particle retention (11 m). It's best for standard qualitative analysis requiring efficient filtration without excessive retention of fine particulates, such as in routine chemical or environmental assays.

Q: Where can I source the Whatman Grade 1 Qualitative Filter Paper in India?

A: You can obtain this product from authorized distributors, exporters, suppliers, manufacturers, and traders throughout India. Ensure you reference Catalog Number 1001-185 for the standard 185 mm, 100-sheet pack.

Q: What is the benefit of using Whatman filter paper with a smooth surface and white color?

A: The smooth surface minimizes sample absorption and ensures even filtration, while the white color makes it easy to observe the separation of particles. This combination guarantees reliable results and simplifies analysis in both observation and documentation.

Q: How does the particle retention capability of 11 m impact analytical processes?

A: A particle retention of 11 m efficiently separates most fine particulates found in standard laboratory samples, ensuring clarity in filtrates and accuracy in qualitative assessments. This level is suitable for general laboratory use where ultrafine filtration is not the primary focus.
