一般描述
Whatman Grade 114V smooth filter paper from Cytiva is wet-strengthened for high mechanical stability. Grade 114V fluted filters are suitable for recovery of large particles and gelatinous precipitates. Note: Grade 114V is strengthened with a chemically stable resin that contains nitrogen. Grade 114V should not be used in Kjeldahl estimations or other nitrogen-sensitive procedures.
Prepleated (fluted) filter papers
Whatman Grade 114V filter paper is wet-strengthened with a chemically stable resin that does not add significant impurities to the filtrate. It is designed for procedures requiring high wet mechanical strength, such as recovery of a gelatinous precipitate after vacuum filtration without filter tearing.
