Titrator Dosing System

Burettes and Dosing

Change reagents without worry.

Our exchangeable Clip Lock™ burette system helps you conveniently separate and switch between your reagents so you don’t have to be concerned about cross-contamination.

Feel confident in your results.

Our unmatched 40, 000 step piston driven dosing pump is capable of dosing extremely small and highly accurate volumes of reagent, helping you achieve a very precise endpoint.

Better design for increased precision.

A dynamic dosing algorithm allows for timely and accurate titration results by providing larger doses near the beginning of a titration and smaller, more precise doses near the titration endpoint.

Display & Navigation


All of your important information is displayed.

Our large color display shows you everything you need to know during testing.

Track your progress in real-time.

Our live titration curve helps you quickly recognize patterns and problems that may arise during your analysis.

Explore titrator menus with ease.

Custom keys allow you to clearly navigate between screens so you don’t get lost.

Titrator Data & Reporting

USB Storage

Highlight your most important information.

Final reports are customizable so you can make sure you are viewing and storing your most important information.

Safeguard the integrity of your data.

Our software allows you to record full GLP (Good Laboratory Practice) data so there is no need to compromise the quality of your results.

Move your information easily across devices.

Use our software or a USB to conveniently transfer files between your titrator and computer.

Titrator Connectivity


View and print reports easily.

You can print reports directly from the titrator with a connected printer and conveniently view results with a connected monitor.

Take advantage of the versatility.

Connect the devices that help you most, whether it be an analytical balance for automatic sample entry or a printer for your reports.
