Whatman 1001-150 Filter Circles, 150mm Dia, Grade 1, 100/pk (PN:1001-150)

Whatman Grade 1 filter paper is one of the most commonly used filters for routine laboratory filtration and qualitative analysis. It is widely used to clarify liquids, separate precipitates, and perform general laboratory filtration in research, education, and quality control laboratories.

This filter paper has a nominal particle retention of approximately 11 µm, which allows it to capture medium-sized particles while maintaining a consistent filtration speed. This balance of retention and flow rate makes it suitable for many standard laboratory filtration procedures.

Whatman Grade 1 filters are manufactured from high-quality cellulose fibers, providing reliable filtration performance and consistent results in routine laboratory applications. The material is designed for qualitative analysis and general laboratory use.

Grade 1 filter paper is known for its medium retention and medium flow rate, which makes it versatile for a wide range of filtration tasks. Because of this balance, it has become the most widely used standard grade filter paper in laboratories around the world.

These filters are commonly used for chemical precipitate separation, environmental sample preparation, soil testing, food analysis, and educational laboratory experiments. Their consistent filtration properties make them suitable for many general laboratory procedures.
