Understanding the GT80 Fully Automatic Potential Titrator


The GT80 Fully Automatic Potential Titrator is a game-changer in analytical chemistry, integrating cutting-edge precision potentiometric titration with an advanced automatic sampler to redefine mass determination standards. Designed for high-throughput laboratories that refuse to compromise data reliability, this instrument streamlines workflows by minimizing manual intervention while delivering unparalleled accuracy. Whether for pharmaceutical quality control, environmental testing, or chemical R&D, the GT80 combines user-friendly operation with robust technology, making it an indispensable tool for quantitative analysis. Its core advantage lies in real-time equivalence point detection with micromolar sensitivity, supported by a dual-electrode system and adaptive algorithms—ideal for labs seeking laboratory automation without sacrificing precision.


Core Features: Powering Reliable & Efficient Analysis


Precision Potentiometric Titration

Equipped with a high-resolution electrode module, the GT80 achieves ±0.1 mV accuracy in potential measurement and 0.001 pH resolution for pH-related titrations. Its adaptive titration algorithm optimizes drop size dynamically: 0.001 mL micro-drops near endpoints ensure precision, while 0.1 mL rapid additions in pre-titration phases boost efficiency. This balance makes it perfect for both acid-base and redox titrations, with consistent results that meet strict analytical demands.


Seamless Automatic Sampler Integration

The 3-axis motion system of the automatic sampler offers sub-millimeter positioning precision, handling sample vessels from 1 mL micro-vials to 100 mL beakers. Standard with 16 stations (optional 20/34/40 stations), it supports unattended batch analysis of up to 100 samples—eliminating human error with barcode scanning. Customizable sampling sequences (including dilution and blank subtraction) via intuitive software further enhance high-throughput analysis capabilities.


Compliance & Data Integrity

Built to meet ISO 17025 and 21 CFR Part 11 standards, the GT80 ensures data security through secure user authentication, audit trails, and encrypted storage. It generates GLP-compliant reports with timestamps via an integrated thermal printer, while USB/Ethernet connectivity enables seamless data transfer to LIMS systems. Hierarchical management and electronic signatures align with FDA, GMP, and GLP requirements, critical for regulated industries.


Robust & Corrosion-Resistant Design

The titrator features a PTFE fluid path (pipelines, burettes, and rotary valves) and stainless-steel pump, ensuring compatibility with aggressive reagents like concentrated acids and bases. A built-in leak detection system triggers automatic shutdown, protecting the instrument and ensuring operator safety. The imported corrosion-resistant PTFE rotating valve and high-power magnetic stirrer further enhance durability and mixing efficiency.
