ChemTron T300 Manual Titration System & Precision Burette Dispenser

Overview

The ChemTron T300 Manual Titration System is a precision-engineered liquid handling instrument designed for laboratories requiring high reproducibility, regulatory traceability, and operational flexibility in classical volumetric analysis. Unlike fully automated titrators, the T300 bridges the gap between manual technique fidelity and digital control—retaining full operator decision-making authority over endpoint detection while eliminating mechanical variability inherent in hand-controlled burettes. Its core architecture follows the gravimetric and volumetric principles defined in ISO 8655-6, ensuring compliance with metrological standards for piston-type dispensers. The system operates on a closed-loop stepper motor drive (8000-step resolution) coupled to a calibrated glass burette, enabling precise volume delivery independent of operator fatigue or visual parallax error. It is widely deployed in QC/QA labs performing pharmacopeial methods (e.g., USP <541>, EP 2.2.20), environmental testing (EPA 300.0, DIN 38409), and raw material assay where standardized manual titration remains mandatory.

Key Features

• Modular design supporting interchangeable 20 mL and 50 mL Duran® borosilicate glass burettes—certified for Class A volumetric accuracy per ISO 385 and DIN EN ISO 8655-3.
• PTFE fluid path throughout: burette tip, piston seal, and tubing ensure chemical compatibility with strong acids (e.g., HCl, HNO₃), bases (NaOH, KOH), oxidizers (KMnO₄), and organic solvents—validated per ASTM D129 and ISO 17025 method validation guidelines.
• Five-step adjustable dispensing rate (0.5–30 mL/min range, dependent on burette size) enables optimization for rapid coarse addition or fine endpoint approach, minimizing overshoot during potentiometric, colorimetric, or pH-based titrations.
• TFT LCD display with wide viewing angle and high contrast supports ergonomic operation across benchtop configurations; interface language support includes English, German, French, Spanish, Chinese, and Japanese—configurable without firmware update.
• Integrated calculation engine with editable formula templates (e.g., % purity, molarity, titer correction) allows real-time result derivation directly on-device; outputs include absolute volume delivered, corrected concentration, and statistical deviation from reference values.
• Full bidirectional communication via USB and RS-232 enables seamless integration with laboratory information management systems (LIMS), electronic lab notebooks (ELN), and balance interfaces—supporting GLP/GMP-compliant workflows with timestamped audit trails.

Sample Compatibility & Compliance

The T300 accommodates aqueous, alcoholic, and low-viscosity non-aqueous media (≤20 mPa·s) typical in acid-base, redox, complexometric, and precipitation titrations. Its UV-protective acrylic shield prevents photodegradation of light-sensitive reagents (e.g., iodine solutions, ceric sulfate). All wetted surfaces meet USP Class VI biocompatibility requirements and are free of leachable metals per ISO 10993-12. The system conforms to EN ISO 8655-6 for volumetric accuracy verification, CE marking under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and fulfills data integrity prerequisites outlined in FDA 21 CFR Part 11 when used with TitriSoft™ software (user authentication, electronic signatures, immutable audit logs).

Software & Data Management

TitriSoft™ software provides method creation, execution logging, and report generation with configurable PDF export. Each titration event records operator ID, timestamp, burette serial number, ambient temperature, delivered volume, endpoint signal (if connected to pH/mV meter), and calculated result—stored in encrypted SQLite database format. Data export supports CSV, XML, and proprietary .TITR formats for LIMS ingestion. The software supports 21 CFR Part 11 compliance modules including role-based access control, electronic signature capture, and change history tracking. Raw data files are write-protected post-acquisition; modifications require documented justification and supervisor approval.

Applications

• Pharmaceutical QC: Assay of active pharmaceutical ingredients (APIs) per USP monographs using NaOH/HCl back-titration or EDTA chelation.
• Food & Beverage: Determination of acidity (titratable acidity as % lactic acid), chloride content (Mohr method), and peroxide value in oils.
• Water & Wastewater: Alkalinity (HCO₃⁻/CO₃²⁻), hardness (Ca²⁺/Mg²⁺), chlorine residual (iodometric), and cyanide (pyridine-barbituric acid).
• Chemical Manufacturing: Standardization of titrants (KBrO₃, AgNO₃), assay of catalysts (e.g., platinum group metals via iodometric titration), and quality release of inorganic salts.
• Academic Research: Teaching volumetric fundamentals with traceable, repeatable instrumentation that eliminates subjective endpoint bias.

FAQ

Does the T300 support automatic endpoint detection?
No—the T300 is a manually controlled system; endpoint determination requires external input (e.g., pH meter, color indicator, potentiometric sensor) interpreted by the user. The device executes volume delivery only upon explicit command.
Can I validate the T300 according to ISO/IEC 17025 requirements?
Yes—its EN ISO 8655-6 certified accuracy, documented uncertainty budget, and traceable calibration certificates (available upon request) support method validation and equipment qualification per ISO/IEC 17025:2017 Clause 6.4.
Is the TitriSoft™ software included or licensed separately?
TitriSoft™ is supplied with the T300 at no additional cost; perpetual license and firmware updates are included for the product’s commercial lifetime.
What maintenance is required for long-term accuracy?
Annual recalibration of the burette assembly and motor encoder is recommended; ChemTron-certified service centers provide traceable recalibration against NIST-traceable standards with ISO 17025-accredited reports.
Can the T300 be integrated into a networked lab environment?
Yes—via USB or RS-232, it connects to local PCs or industrial PLCs; TitriSoft™ supports OPC UA server mode for integration into SCADA or MES platforms.
