Automated Titrator

icon-wave

OMNIS automated titrator is a fully automated robot pick & place module and rack plates, for a higher throughput. This system measures electrical conductivity, pH value, alkalinity, calcium and magnesium hardness and total hardness. Titrator is commonly used in quantitative chemical analysis, to determine an unknown concentration of a known substance in the sample. 

What kind of research is applicable / suitable for this equipment? 

  • Water industry - to test water on various parameters, such as chemical content and pH, to allow a more efficient water treatment 
  • Food industry – to determine the quantity of a reactant in the sample 
  • Biodiesel fuel in the automotive industry – analysis and optimization of fuel pH for the most efficient biodiesel fuel production  
  • Pharmaceutical industry – to determine the proper mix when compounding medicines  

Any chargeable costs for equipment usage? 

Yes, please approach Lab Manager or search the handbook (Section A6 – Schedule of rates for specialist facilities) for more details.
