Titrets® simplify titration tests just as CHEMets® and Vacu-vials® simplify colorimetric tests.  

Each Titret® contains a carefully measured quantity of titrant sealed under vacuum.  The sealed tip is fitted with a miniature valve that is used to control the flow of sample into the ampoule as the analyst performs what is known as a "reverse titration."  

Sample is drawn into the ampoule in small increments (with mixing) while the analyst watches for the color change which signals the end-point of the titration.  When that change occurs, the ampoule is placed in an upright position and the test result is read opposite the location of the liquid level, using a scale printed on the side of the tube. 

The entire process requires only a minute or two and avoids all the equipment hassle and clean-up associated with ordinary titrations.
