WHATMAN™ Filter Paper No. 41 – 12.5 cm (125 mm)
Product Description
WHATMAN™ Grade 41 Filter Paper is a high-quality, ashless quantitative filter paper designed for fast filtration of coarse or gelatinous precipitates. With a diameter of 12.5 cm (125 mm), it is widely used in analytical laboratories, research facilities, pharmaceutical industries, chemical laboratories, and industrial quality-control applications.
Grade 41 is known for its high flow rate and relatively large particle retention, making it suitable for applications where rapid filtration is required. The ashless grade is especially suitable for gravimetric analysis, as it leaves very low ash after ignition.
