Papers demonstrate high wet strength and chemical resistance and have a hardened and highly-glazed surface that can withstand wet handling and scraping. The 2.7 µm size retains very fine crystalline precipitates. Slow flow rate.
The thinnest of all GE Whatman® papers – retains very fine precipitates
Virtually no loose surface fibers – suitable for use in integrated circuit carriers for electronics
