Description
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.
- 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.
