WHATMAN™ Grade 42 Ashless Quantitative Filter Paper | 125 mm Diameter | 2.5 µm Particle Retention | 100 Circles | Cat. No. 1442-125
Product Description
WHATMAN™ Grade 42 Filter Paper is a premium-quality ashless quantitative filter paper designed for fine precipitates and analytical applications requiring high particle retention. With a diameter of 12.5 cm (125 mm), this filter paper is widely used in chemical laboratories, research institutions, pharmaceutical testing, environmental analysis, and industrial quality-control applications.
Grade 42 is known for its fine particle retention and slow filtration rate, making it suitable for the collection of very fine precipitates. Its high-purity cellulose construction and low ash content make it particularly suitable for quantitative and gravimetric analysis, where the filter paper may be ignited after filtration.
