One click titration: a new line of automatic titrators makes titration as simple as pushing a button.
The Titration Excellence is a modular system for automatic titration. It allows the fully automated titration of single samples or batches of samples following preprogrammed or custom methods. Results can be evaluated using different evaluations and criteria and documented via printout or connection to PC software. To adapt to customer applications and workflows, the system is fully modular using concepts such as easy connection of dosing modules via magnets. Thanks to a high degree of self-configuration and automation, the Excellence Titrator enhances productivity and avoids operator mistakes.
Titration Excellence features a highly modular design, allowing the end user to configure a system that exactly suits the needs of the laboratory, resulting in a tailored, compact system. Additional dosing units can be connected with a simple CAN bus cable. Internal magnets attach the dosing units to the main unit, helping maintain compactness. The titrator can have one of two user interfaces, either connecting to a PC with LabX v. 2.5 Titration software or to the Titration Excellence touch screen terminal.
The titration stand that is chosen is also up to the end user. For single samples, a manual titration kit is chosen. For higher sample throughput, either a Rondolino (nine samples) or Rondo60 (up to 60 samples) can easily be configured. Additional sensor boards can also be added at any time, such as additional pH boards or a conductivity board.
The overall value of the modularity is that all units are fully expandable, both now and in the future. All printers, sample changers, burettes, pumps, and many other peripherals are true plug and play so upgrading is easy.
Making titration easy
The ease of use of the new titrators strongly ties to one key accessory, the Titration Excellence terminal. It's a touch sensitive terminal that can either be activated with fingers or with a pen/stylus. The touch sensitive area (the Home Screen) is the main graphical user interface and is where "hot keys" are configured. This where a user starts methods, sample series, and manual operations, such as stir, dispense, and rinse, via shortcuts. Ay of these shortcuts can be created as One Click shortcuts, so laboratory operations are made as simple as possible.
The method editing capabilities also contribute to simple operation, as creating and editing a method is intuitive. By clicking an "insert" key, the user can add any number of functions to customize methods. This leads to quick method development.
Efficiency in analysis
Everything with Titration Excellence starts with One Click. All analyses, methods, and series, no matter how complex, can all be started from the Home Screen. Up to 30 different users can be defined, and each can have a dedicated Home Screen, so the user only see the shortcuts that he/she defined.
There is no need for configuration of different peripheral devices due to the true plug and play technology that has been implemented. The titrator automatically recognizes and configures new burettes and dosing units as well as other peripherals such as sample changers, pumps, printers, and computers.
Automation possibilities are numerous. Up to seven dosing units can be added to the T90 for both dosing and titrating purposes. A Rondolino or Rondo autosampling unit can be added to perform titrations, including the rinsing and conditioning of the electrode. The many pump inputs located on the back of the unit allow the automatic dosing of solvents or auxiliary reagents.
An additional new feature of Titration Excellence is the intelligent burette. A radio frequency identification (RFID) sensor has been added to all dosing units. This sensor automatically reads the RFID chip seated in the new burette assemblies. If it is a new burette, the titrator will ask which titrant is being used and its nominal strength. When performing a standardization of that titrant, these values, along with the date and time, are stored on the chip. When the burette is removed and put back in the future, the titrator immediately knows which titrant is on which drive along, including all of the titrant's history. Attempting to perform a titration with the wrong titrant is not allowed, as the user will be stopped and asked to put the correct titrant in place before going further. The new burettes also allow the titrator to warn the user when the titrant is about to expire.
Additional security features included with the Titration Excellence are the user management capabilities. Each user's Home Screen can have its own password to eliminate accidental changes to titration methods. Also, 21CFR Part 11 compliance for regulated industries can be facilitated with the use of LabX Titration Software. These security features help prevent errors, simplify the operation of the instrument, and help complete GLP documentation.
