Whatman Grade 542 Ashless Fine Precipitate FIlter, 110 mm circles, 100/pk
High wetstrength
Acidhardened 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)
Cytiva's Whatman Grade 542 filters are acid hardened to allow high retention of fine precipitates in applications such as metal determinations and hydroxide collection.
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.
