Whatman Quantitative Filter Papers, Hardened Ashless, Grade 540
GE’s Whatman Grade 540 is a high-purity, acid-treated cellulose lab filter paper. Mechanically strong Grade 540 is well suited for quantitative or gravimetric analysis of strongly acidic or alkaline samples.
Acid-treated for high wet-strength
Extremely low ash content (0.006% ash maximum)
Nominal particle retention of 8 µm
Medium flow rate (Herzberg filtration speed 200 s)
High chemical resistance to strong acid and alkali suspensions
GE Healthcare’s Life Sciences business offers hardened ashless filter paper for a variety of precipitate sizes. Along with general filtration Grade 540, the range includes Grade 542 for retention of fine precipitates and Grade 541 for fast filtration. All three grades are designed for use in gravimetric analysis.
Gravimetric analysis of acid and alkali suspensions
GE’s hardened, ashless Grade 540 lab filter paper is frequently used as a gravimetric filter during analysis of metals in acidic or alkaline solutions and in the collection of hydroxides. The acid-treated surface prevents tearing during filtration and allows the user to scrape precipitates from the paper.

GE’s Whatman Grade 541 acid hardened cellulose filter paper features high wet-strength, high chemical resistance, and a large nominal particle retention for fast analytical filtration.
High wet-strength
High chemical resistance to strong acid and alkali suspensions
Retention of gelatinous precipitate
22 µm nominal particle retention rating
Fast flow rate (Herzberg filtration speed 34 s)
Maximum of 0.006% ash concentration
Along with fast Grade 541 filter paper, the hardened, ashless range from GE Healthcare’s Life Sciences business includes general-purpose Grade 540 and Grade 542 for fine particle retention. All three paper grades are appropriate for use in gravimetric analysis with strong acids and alkali samples.
Gelatinous precipitate retention
Hardened ashless filter paper is recommended when fast filtration of a gelatinous precipitate for gravimetric analysis is performed on a strongly acidic or alkali solution. Applications of Grade 541 papers include:
Use as an animal foodstuff filter for determining fiber content
Determination of gelatin content in milk and cream
Quantification of chloride in cement, as well as chloride and phosphorous in coal and coke
Specification
Grade :Grade 541
Format :Sheet
GE’s Whatman Grade 542 filters are acid hardened to allow high retention of fine precipitates in applications such as metal determinations and hydroxide collection.
High wet-strength
Acid-hardened for resistance to strong acid and alkali solutions
Nominal particle retention rating of 2.7 µm
Herzberg filtration speed of 2510 s
Extremely low ash content (0.006% ash maximum)
Slow flow rate filters for gravimetric determination
Hardened Grade 542 quantitative papers enable high retention of fine particles in chemically harsh conditions. When acting as a gravimetric filter, this cellulose filter paper is therefore well suited for use in capturing fine precipitates in applications such as metal determinations and hydroxide collection.

Whatman Multigrade 150 Glass Fiber Filter
GE’s Whatman GMF 150 prefilters are multilayer graded density filters for rapid and efficient filtration of samples with high solids content.
Compared to an unprotected membrane, greater sample volume can be filtered
Higher particulate loading capacity and faster flow rates than uniform prefilters
Excellent particle retention (both large and small particles)
100% borosilicate glass, binder-free
Extends life of final filter membrane
Multilayer filter design
When a sample is applied, the multigrade glass filter traps larger particles in its pores or on the surface of the coarse layer, medium-sized particles in the interface meshing, and smaller particles in the interstices of the fine layer.
Specification
