Details
This Whatman,1444-090, Grade 44 filter paper has a diameter of 90 mm and comes in a pack of 100.
Grade 44: Thin version of Grade 42 retaining very fine particles but with lower ash weight per sample and almost twice the flow rate of Grade 42.
Cytiva's Whatman Grade 44 quantitative paper is a thin version of Grade 42 ashless paper. The thinness reduces the overall ash content, making Grade 44 well suited for analyses relying on ash-free dry weight.
Features:
Accurate ash free dry mass measurements
Fine nominal particle retention rating of 3 µm
Filtration speed (Herzberg 995 s)
Typical thickness of 180 µm
