Not only are the tests accurate and precise, but contact with potentially hazardous materials is kept to an absolute minimum. The procedures are all based on standard or accepted methods of laboratory analysis. They are designed to meet user's complete requirements for conformity testing and analytical quality control. The Tubetests range includes all of the main parameters needed for water and effluent monitoring, and for the testing of agricultural run-off and leachate from landfill sites. The Tubetests reagent system offers a choice of test methods based on the traditional Nessler method or the more recent Indophenol procedure.
Phosphates promote eutrophication in natural waters.
Testing for this parameter is therefore important for environmental control. Tubetests Reagent Packs Palintest Tubetests for Metals New for 2000, the Palintest Tubetests metal tests provide the same convenient and rapid test format used for other Tubetests and allow measurement of copper, iron, zinc, nickel and chromium. Effluent samples may be heavily coloured, at extreme pH, contain strongly bound complexed metals or thick precipitate of insoluble material. Acid digestion is used to destroy colour, dissolve precipitates and free metals from complexes, providing a much more accurate and effective test for effluent than conventional water test kits. 404 A Tubetest Metals brochure is now available in PDF format to download.
