Automatic Titrator – Titra


Titration is the fundamental chemical analysis procedure whereby concentration of chemical substance in solution is determined by reacting it with measured amount of another chemical. Auto titrator performs this analysis using motor driven dispenser, stirred reaction vessel and electrodes which sense the completion of reaction by measuring the potential difference between two electrodes. Making use of this instrument, it is possible to increases the accuracy, repeatability, reproducibility and minimize the error in calculation and documentation

The Instrument provides the following modes of Titration:

  • Incremental: Incremental titration operates with user selectable fixed dose and fixed intervals till endpoint is detected or volume limit is reached.
  • Equilibrium: .This is universal and dynamic titration. In this titration, the dose and time automatically get tuned to the titration trend with evaluation of endpoint.
  • PH Cut-off/STAT: a) In PH cut-off mode, the end point is determined in a preselected PH window. b) in PH-STAT mode, the PH value is maintained until the pre-selected time interval is fulfilled.
The following Titrations are possible with TITRA

  • Acid-base or aqueous titration
  • Redox titration
  • Complexometric titration or EDTA titration
  • Blank titration
  • Silver Assay Titration ( As per BIS 2113: 2002)
  • Nonaqueous titration
  • Argentometric or Precipitation titration
  • Voltametric titration/KF Titration
  • Back titration

  • Pharmaceuticals and Biochemistry
  • Food and beverages
  • Pesticides and Fertilizers
  • Metallurgy and Electroplating
  • Environmental and Water Pollution
  • Dyes and Chemicals
  • Petrochemicals, Plastics and polymers
  • Jewellery Industry

TITRA is provided with two-point auto calibration and standardization ( Zero offset). The instrument is capable of displaying pH and mV of the samples, with temperature compensation, TITRA can accept a variety of electrodes to cater to various applications in different fields. The liquid path comprises Teflon tubings, Teflon lined valve and gas tight burette with Teflon plunger head. It creates chemically inert system for any sensitive analysis. The instrument is supplied with high speed vortex stirrer with digital speed indication. This specially designed stirrer provides excellent homogenous mixing of samples. An optional magnetic stirrer is also available.

Result Calculation

TITRA has user selective end point result calculation as follows

  • Result calculation by highest potential jump
  • Result calculation by last potential jump
  • Result calculation with selected potential jump
  • Result calculation with potential jump in window of selected parameters for example- TAN/TBN analysis
