Manual titrations are time consuming and can be inaccurate at times due to human error. Not to mention, important data can get easily lost due to improper tracking methods. The Thermo Scientific Orion Star T900 Series Automated Titrators are designed to make performing titrations easier, more reliable, and more reproducible than manual titrations.
These auto titrators expand the number of ions and compounds that can be measured beyond direct electrode analysis and offer dynamic process controls that adjust the titration to optimize analysis results.

Automated vs. Manual Titration
Manual titration can be a time consuming and frustrating process. Watch how easy it is to find the endpoint, reproduce your workflow, and optimize your results. The auto-filling burette helps to minimize the handling of corrosive materials. Use of an auto titrator well help ensure a safer, more efficient lab.
Water treatment plant streamlines their manual titration methods
A water treatment plant in the midwestern United States that ran up to 10,000 titrations each year improved their workflow. Learn how streamlining the workflow using an Orion Star Automated Titrator for low-level alkalinity titrations benefited the lab.
Using an auto titrator to overcome top titration challenges
Do you encounter challenges with titration?
- Have you dealt with chemical spills or broken glassware while trying to fill the burette?
- Ever missed the titration end point using color indicators?
- Do you receive inconsistent results due to subjective interpretations of the end point color change?
- Do you have to manually calculate sample concentration and log the details?

Three reasons why its time to stop performing manual titrations
Performing manual titrations can be extremely tedious, requiring the operator to stand in one place, watching minuscule droplets drip into a sample container and diligently waiting for the color change or other endpoint indictor to occur before starting the process all over again, for possibly hours and hours of repeated sample titrations.
An automatic titrator allows you to start the titration and then walk away from the titrator to perform other tasks or tests while the titrator takes care of the titrant addition, endpoint detection and results calculations automatically without any involvement from the operator.
Once the titrator is done, the titrator will beep, notifying the operator that the results are available and another titration can be started.
Manual titrations typically use a non-certified, Class B or Class A burette with stopcock to add doses of titrant to the sample. The operator uses the stopcock to start and stop the additions of titrant into the sample, often one drop at a time, until the endpoint is reached.
The precision of these additions, especially near the endpoint, is primarily determined by the operator’s skill level, experience and focus on the task at hand. All too commonly, an operator can allow too much titrant to flow out of the burette into the sample and overshoot the endpoint, requiring them to perform the entire titration all over again. Even highly skilled and experienced operators can be limited in the precision of their manual titration results by the last few drops of titrant, since each drop can vary in volume.
When using an automatic titrator, the titration is performed using a high-accuracy titrant delivery system that controls all titrant additions into the sample and will adjust the dose rate as it detects the endpoint approaching.
Once the endpoint is reached, the titrator uses the precisely measured volume of titrant added to the sample to automatically calculate the concentration results for the sample. The operator’s skill level, experience and focus on the task at hand is no longer a factor in the overall accuracy of the titration results and the possibility of missing the endpoint is greatly reduced.
Typically calculating titrations in the lab is done by calculating the sample concentration after the endpoint has been reached. There are many points in this calculation where human error can get in the way of consistent, reproducible results.
When using an auto titrator, it will automatically calculate the sample concentration from the entered parameters. Plus, on the automatic titrator, electrode, titrant and titration setup parameters can be saved as a method, so the exact same settings are used for each titration. These methods can be transferred between titrators for consistent procedures to be used on multiple titrators or multiple labs. This way you can save time with repeat titrations by running the exact same parameters each time without having to reenter any information.
Instead of manually logging the titration results in a notebook or scrap of paper, an auto titrator will automatically save the titration results in the data log with time and date stamp.
