Intermediate particle retention rating of 16 µm
Herzberg filtration speed of 155 s
Particle collection between that of Grades 40 and 41

Cytiva offers other ashless grades to ensure that you have the appropriate particle retention rating for your needs. Hardened ashless grades are also available for analyses that use strong acid/alkali solutions.

Particle collection and inorganic analysis

Whatman Grade 43 from Cytiva's business can be ashed during gravimetric analysis without contributing substantially to the measured weight. These filters are also appropriate for:

Inorganic analysis in the construction, mining, and steel industries
