Mettler Toledo DL53 Microprocessor-Controlled General-Purpose Analytical Titrator

The Mettler Toledo DL53 is a microprocessor-controlled general-purpose analytical titrator designed for accurate and reproducible potentiometric, voltammetric, amperometric, and conductometric titrations. Featuring built-in intelligence and a graphical display capable of rendering E vs V titration curves in real-time, the DL53 supports complex applications essential in biotechnology, molecular diagnostics, and biochemical analysis.

Key technical features include:

• Support for end point, equivalence point, and pH-stat titrations
• Compatibility with a memory card (not included) for storing titration methods, configurations, and results
• Integration with the DM143-SC double pin platinum electrode for voltammetric and amperometric analysis
• Specialized titration capabilities such as:
• Karl Fischer water determination—critical for moisture analysis in biochemical sample prep and bioprocessing
• Bromine and Vitamin C quantification
• Sulfur dioxide analysis in enology (wine chemistry)
• Measurement of solution potential, pH, and temperature
• Determination of Total Acid Number (TAN) and Total Base Number (TBN), relevant for quality control in biopharmaceutical production pipelines
• Ability to perform conductivity measurements and conductometric titrations with third-party analog devices
• Expandable sensor interface including multiple pH sensor inputs and polarized inputs for advanced voltammetric/amperometric assays
• External device connections via TTLIO and DIN sockets supporting keyboards, barcode readers, analog recorders, and remote control
• Preloaded with 20 application methods developed by Mettler Toledo, enabling rapid setup across research and industry workflows
• Upgrade path to newer DL55 or DL58 models for scalability

The DL53 titrator is widely adopted in biotechnology research, molecular cloning workflows, synthetic biology experimentation, and molecular diagnostics laboratories where precise titration and quantitative analysis are essential.

*Note: The offered unit in this listing is incomplete and sold AS-IS; the propeller/stirrer is damaged and memory card is not included.* For full operational use, refer to the official Mettler Toledo DL53 manual and consider necessary accessory acquisition.

This potentiometric and volumetric titrator remains a robust choice for researchers requiring precise acid-base, redox, and moisture content determinations critical in biochemical analysis, quality control, and biomanufacturing environments.
