Details
This Whatman,1442-110, Grade 42 filter paper has a diameter of 110 mm and comes in a pack of 100.
Grade 42: A world standard for critical gravimetric analysis with the finest particle retention of all Whatman cellulose filter papers Typical analytical precipitates include barium sulfate, metastannic acid and finely precipitated calcium carbonate.
Cytiva's Whatman Grade 42 quantitative papers have the finest retention of all Whatman ashless filter paper grades. Grade 42 is designed for gravimetric analysis and sample preparation for instrumental analysis.
Features:
Ashless: 0.007% ash maximum
Fine (2.5 µm) nominal particle retention rating, eliminates large particles that might otherwise interfere with sensitive instrumentation
Herzberg filtration speed of 1870 s
Commonly used as a calcium carbonate filter
