Pure and ultra-pure water

Water is required in chemical, biological and analytical laboratories for many applications and with different specifications. In the Th. Geyer online shop you will find the right equipment to produce the right water for your application: double distilled, deionised, ultra pure, for chromatography, for microbiology, for analysis or for trace analysis. We carry equipment from well-known suppliers such as ELGA LabWater, stakpure, Sartorius and Millipore, which are equipped with different technologies like reverse osmosis, EDI, ion exchange, UV and various filters. In addition, all needed accessories and consumables are available for these.

 Reverse osmosis systems, Ultra Clear™ RO EDI

Evoqua

The well-proven Ultra Clear™ RO range has been enhanced to peak water quality level in the plus series by adding electronic deionisation cells: accessory deionisers for removing inorganic materials from the output are therefore no longer required.
Technical parameters:

  • Resistance up to 17 megohm (0.07µS/cm)
  • TOC < 5 to 20ppb at RO cell output
  • Typical pure water quality < 0.07µS/cm
