GT-310

High-Precision, Multi-Channel Automated Titration for Modern Laboratories

The Nittoseiko GT-310 Automatic Titrator is a next-generation titration platform designed to deliver highly accurate, repeatable and compliant titration analysis across a wide range of applications. Combining a precision automatic buret, advanced titration-control algorithms, and multi-channel expandability, the GT-310 offers unmatched efficiency for quality control laboratories, chemical analysis, research facilities and industrial testing environments.

With support for potentiometric titration, Karl Fischer titration and optional conductivity/polarization titration, the GT-310 provides a robust analytical solution with seamless data integrity and LIMS connectivity.

Key Features & Advantages

🔄 4-Channel Multi-Titration System

Up to four titrators—potentiometric and Karl Fischer—can be connected to a single multi-controller, allowing:

• Simultaneous multi-sample measurement
• Mixed titration setups (acid–base, redox, chelatometric, Karl Fischer, etc.)
• Centralized control of all units

Ideal for high-throughput laboratories that need parallel titration workflows.

🧪 Automatic pH Calibration

Equipped with an automatic stability-judgment function, enabling:

• Fully automated pH calibration
• Smooth transition from calibration to sample measurement
• Enhanced usability when combined with the optional GT-310MST Multi-Sample Titrator

📝 Reanalysis Function

Allows retrospective adjustment of the endpoint detection method without repeating the titration.
Selectable modes:

• Inflection point
• Set potential
• Front intersection
• Rear intersection
• V-intersection

This offers superior flexibility for method development and complex sample matrices.

🌐 LIMS Connectivity

The multi-controller automatically transfers measurement data directly to your laboratory network, providing:

• Centralized record keeping
• Integration with existing LIMS workflows
• Real-time data availability

🔐 Integrated Data Integrity

The GT-310 includes strong built-in data-protection features without requiring a dedicated PC.
