WHATMAN Polydisc TF 盤(pán)式特氟龍濾器的詳細(xì)介紹WHATMAN Polydisc TF 盤(pán)式特氟龍濾器WHATMAN Polydisc TF 
盤(pán)式特氟龍濾器 含有PTFE膜,適合于化學(xué)腐蝕性強(qiáng)的溶液,有機(jī)溶劑,適合做真空泵保護(hù)器,1微米濾頭含有聚丙烯預(yù)過(guò)濾層,適合高污染的樣品

This device features a PTFE membrane which is ideal for chemically aggressive 
solutions, reagents and organic solvents. This lightweight unit is particularly 
suitable for protective vents and for in-line filtration and isolation 
applications. The 1 μm device features a polypropylene prefilter for use with 
heavily contaminated samples.
Features and benefits 
  Solvent resistant membrane
  Chemical resistant housing
  Hydrophobic PTFE membrane
  Autoclavable (multiple times)
  Integrity-testable (bubble point or water breakthrough pressure ‘in situ’ 
  methods) 
  Biosafe
  Lightweight (11.5 g for Polydisc and 17.9 g for ReZist); avoids the collapsing 
  of tubing which can be caused by heavy filter devices

Applications 
  Pharmaceutical: vents and in-line applications
  Biotech: sterile vents and exhausts for growth environments, in-line 
  sterilization of gases
  Laboratory: clean or sterile gases. Filtration of solvents and reagents. 
  Drying gases.
  Electronics: photoresists, solvents, gases for research
