TITRALAB 1000 series automatic potentiometric titrator

Working principle:

An automatic potentiometric titrator is a common analytical instrument designed based on the principle of potentiometry for volumetric analysis. An appropriate indicator electrode and reference electrode are selected to form a working cell with the test solution. As the titrant is added, due to the chemical reaction, the concentration of the measured ions continuously changes, and therefore the potential of the indicator electrode changes accordingly. Near the titration endpoint, the concentration of the measured ions changes abruptly, causing a sudden jump in the electrode potential. Therefore, the titration endpoint can be determined based on the sudden jump in electrode potential.

Application industries:

• The Titralab®1000 series automatic potentiometric titrators can be used in many fields such as chemical, petrochemical, cosmetics, biotechnology, food and beverage, environmental, surface treatment and electroplating.

• Among them, the TIM854/856 trace moisture analyzers also feature constant pH/mV titration functionality. By monitoring the addition of acid or base to maintain the reaction system at a specific pH/mV value, they can be widely used in biological and pharmaceutical fields, especially for the determination of enzyme activity, sustained-release drug kinetics, and series of reactions requiring a constant pH/mV value.

• The TIM9XX series rapid moisture analyzers also feature wireless RFID technology, which can automatically identify relevant information of the titrant.

Instrument features:

• 1) The TitraLab® series automatic potentiometric titrators use a burette with 1/20000 resolution to make experimental results more accurate, with titration volume accurate to 0.001mL.

• 2) This series of automatic potentiometric titrators is equipped with a large-screen LCD display, which can display the titration curve, electrode and titrant status in real time.

• 3) The TitraLab® series automatic potentiometric titrators have good expandability and can be connected to printers, autosamplers, scanners, sampling pumps, etc., to achieve efficient and intelligent potentiometric titration operations.
