Whatman Qualitative Filter Paper 2V 185 mm 100 Filters

Description

The Whatman 1202185 Qualitative Filter Paper is a laboratory consumable designed for general-purpose filtration. These filter paper circles have a diameter of 185 mm, making them a standard size for a variety of filtration applications. They are made from high-quality cellulose, a material known for its reliability in routine laboratory tasks.

These filters are classified as Grade 2V, which indicates they are pre-pleated, or fluted. This pre-folded design offers several advantages over flat circles, including a faster flow rate, increased loading capacity, and a reduction in filtration time because the paper exposes a larger surface area. The nominal particle retention rating is 8 µm, making it suitable for filtering fine particulate suspensions. Whatman Grade 2V filter paper is commonly used for a wide range of applications, including filtering precipitates like lead sulfate and calcium carbonate.
