Whatman Quantitative Filter Papers, Hardened Ashless, Grade 542

Whatman Quantitative Filter Papers, Hardened Ashless, Grade 542

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)

Along with Grade 542 cellulose filter paper, the Whatman range of hardened quantitative papers from GE Healthcare’s Life Sciences business includes fast Grade 541 and general-purpose Grade 540 filters. All three grades are designed for use in quantitative analysis with strong acid/alkali solutions.

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.
