In modern laboratories, precision and efficiency are critical. Whether in chemical analysis, food inspection, or pharmaceutical research, manual titration often becomes a time-consuming process prone to human error. The Automatic Titrator provides a breakthrough solution, simplifying complex titration workflows while ensuring repeatable accuracy and compliance with laboratory standards.
Among the latest innovations, the Zhuoguang GT60 Automatic Potential Titrator stands out as a high-precision system that automates traditional titration experiments such as sodium chloride concentration and sodium hydroxide content determination. With features like acid- and alkali-resistant PTFE construction, high-precision closed-loop control, and automatic data processing, it represents a new generation of intelligent titration instruments.
An Automatic Potential Titrator is an analytical instrument that measures the concentration of a solution by automatically adding titrant until a defined electrical potential or pH endpoint is reached. Unlike manual titration, it eliminates subjective judgment, delivering precise results with minimal human intervention.
The Zhuoguang GT60 uses a high-precision burette with 1 μL resolution, supported by closed-loop control technology to ensure accurate dispensing at every step. Its PTFE titration pipelines and rotary valves provide exceptional resistance to acid, alkali, and corrosion—ideal for various chemical environments.
It supports multiple titration methods, including acid-base titration, redox titration, precipitation titration, complexation, and non-aqueous titration. The system also complies with GMP, GLP, and FDA specifications, making it suitable for laboratories with strict quality management standards.
| Feature | Description |
