Model 350/360 Potentiometric Titrators
Simple. Accurate. Affordable.

Denver Instrument’s volumetric titrators are the ultimate automated solution. Simple enough for routine testing but equally suited for advanced analysis and reporting.

These instruments make quick, easy work of common titrations, because the titrator arrives pre-programmed for your specific applications. Setup is simple and you’re titrating in no time. Typical results are obtained in minutes and are repeatable with a relative standard deviation of less than 1%.

End point or inflection point titration. Incremental monotonic or dynamic titrant addition modes provide accurate results whether you are working with sharp or weak curves or running single or multiple inflection points. Continuous addition allows you to reach end points or determine inflection points quickly.

pH STAT methods for enzymatic studies, synthesis experiments and crystal growth studies are standard in the Model 360 (one burette) for one way titration and the Model 362 (two burettes) for two-way titrations. AAA and PID algorithms are standard preprogrammed methods.

The titration assistance program checks the method and if necessary directs you to the appropriate screen for correction. You can enable password protection for routine titrator operation use or disable password protection for supervisor method development.

Numeric keypad, navigation arrows and menu driven messages makes operation of the titrator easy.

Store up to 200 results in non-volatile memory and review your titration data via the instrument display, optional serial printer or laboratory computer. Time and date stamp of all titrations means full traceability of QC samples (if required) and regular samples.

• High-resolution, 18,000-step burette drive assures precise and accurate titrant delivery.
• Easy one-button operation for operators of all skill levels.
• Store up to 60 results and 10 methods in non-volatile memory.
• Get results on the instrument display, optional printer or laboratory computer.
• Automate your titrations with a 20-position sample changer for unattended operations.
• Optional data collection software is available for advanced analysis of your results.
