SCHOTT Instruments TitroLine easy Automatic Titrator – Digital pH/mV Titration System

The SCHOTT Instruments TitroLine easy Automatic Titrator is a laboratory analytical instrument designed for routine titration, pH measurement, redox analysis, and quantitative determination of chemical substances in liquid samples. Manufactured by SCHOTT Instruments, this compact titration system combines automated liquid dosing with electrochemical measurement capabilities, making it suitable for laboratories that require consistent analytical results and reliable liquid handling.

The TitroLine easy integrates a motor-driven piston burette, a pH/mV measuring system, and an electronic control interface. It is designed to simplify routine titration procedures by allowing laboratory operators to select predefined methods and initiate measurements through the instrument's control panel. Depending on the selected method and configuration, the instrument can perform endpoint titration, automatic equivalence-point detection, or manual titration. These capabilities help reduce repetitive manual operations and improve workflow efficiency in analytical laboratories.

The instrument features a digital LCD display and a straightforward keypad for accessing operating functions, calibration settings, filling operations, and titration controls. The pictured unit displays a filling operation, which is consistent with the instrument's liquid-dosing functionality. Its compact benchtop design makes it convenient for laboratories with limited workspace.

The TitroLine easy supports pH measurements across a range of 0.00 to 14.00 and millivolt measurements from approximately −1400 to +1400 mV. Depending on the connected electrode and the analytical method, these measurements can be used to identify titration endpoints and assess chemical characteristics of samples. A compatible temperature sensor can also be connected for temperature measurement and compensation where required.

One of the instrument's important components is its 20 mL DURAN borosilicate glass dosing cylinder with UV protection. The dosing assembly uses a motor-driven valve constructed from chemically resistant PTFE and ETFE materials. FEP tubing provides a suitable liquid pathway for compatible laboratory reagents. These construction features are intended to support reliable reagent dispensing during routine analytical work.

The TitroLine easy offers two-point pH calibration using stored buffer solution values. This enables users to calibrate a compatible pH electrode before performing measurements. The instrument also provides an RS-232-C interface for connecting compatible computers or printers for data documentation. A compatible magnetic stirrer can be connected to help maintain sample homogeneity during titration.

The SCHOTT Instruments TitroLine easy can be used in pharmaceutical quality-control laboratories, chemical testing facilities, food and beverage laboratories, water analysis laboratories, educational institutions, and industrial research environments. Typical applications include determining acidity, alkalinity, chloride content, salt concentration, and selected oxidation-reduction parameters, depending on the electrode, reagents, and method used.

For pharmaceutical and chemical laboratories, automated dosing can help improve repeatability by controlling reagent delivery more consistently than purely manual dispensing. In food and beverage testing, the instrument can support acidity and salt-content measurements. In environmental laboratories, suitable titration methods can be used for selected water-quality parameters.

The compact enclosure, integrated measuring electronics, predefined methods, and automated dosing functions make this model a practical option for laboratories performing routine volumetric and electrochemical analyses. Before purchasing a used unit, laboratories should verify the condition of the dosing cylinder, tubing, valve, display, electrode connections, and calibration performance.

This listing describes the general capabilities of the TitroLine easy model. The exact accessories, software, operating condition, and included electrodes should be confirmed against the actual unit being offered for sale.
