  • Background Information
  • Accessories for Glass Filter Holders – XX100900, XX1604705, XX1604706, XX1009010, XX1009002 The All-Glass Filter Holder was designed for the filtration of aqueous and organic or corrosive liquids for particulate contamination analysis. The holder can also be used for HPLC solvent preparation. The vacuum connection is integrated into the filter holder base and flask cap, above the filtrate exit level. With this design, you can avoid unintentionally drawing filtrate into vacuum tubing. This design also allows simple transfer of filtrate (i.e., HPLC solvents) by pouring from the receiver flask.These part numbers are accessory items for the all glass filter holders.Features & Benefits:•All-glass construction has broad chemical compatibility •Borosilicate glass parts contact liquid, with ground-glass sealing surfaces •Vacuum connection to flask cap simplifies transfer of filtrate Applications:Particle Contamination Analysis, HPLC Solvent Filtration, General Filtration and Clarification
