- 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

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.
Looking for a filter paper, membrane filter, or syringe filter? Let Cytiva help you find the optimal filter for your needs to ensure reliable analysis.
