沃特曼whatman硬化(huà)低灰(huī)定量濾紙GRADE 50的詳(xiáng)細介(jiè)紹(shào)Grade 50: 2.7μm whatman硬(yìng)化低灰(huī)定量(liáng)濾紙GRADE 50
Retention of finest crystalline precipitates. The thinnest of all Whatman filter 
papers. Slow flow rate. Hardened and highly glazed surface. This finish also 
keeps the paper free from loose surface fibres. Highly suitable for qualitative 
or quantitative filtrations requiring vacuum assistance on Büchner or 3-piece 
filter funnels. Very strong when wet. Will withstand wet handling and 
precipitate removal by scraping. In the electronics industry, the virtual 
absence of fibre shedding is utilised in carriers for integrated circuits.
