The Thermo Scientific™ Orion Star™ T920 redox titrators are designed to increase your laboratory productivity by automating titrations.
Our core electrochemistry technology is integrated with a state-of-the-art reagent dispensing system to create modern, simplified automated titrators designed to make performing titrations easier, more reliable and more reproducible than manual titrations.
Use the Orion Star T920 redox titrator for dedicated redox titrations including:
- Sulfite/SO2 in juice and wine
- Reducing sugar in juice and wine
- Ascorbic acid (vitamin C) in food products
- Peroxide value in food products
- Dissolved oxygen in wastewater by Winkler
- Organic matter in soil
Titration techniques include equivalence point titrations and preset mV endpoint titrations for versatile sample analysis. The automated titrant delivery system with high-accuracy burette and dispenser provides consistent results. Automatic results calculations simplifies analysis and reduces computational errors.
This compact titrator is designed to:
- Offer easy-to-use navigation from setup to live titration analysis to data transfer
- Showcase titrations, onscreen instructions and help menus on a large color graphic touchscreen display
- Create and save up to ten user-defined methods
- Save up to 100 titration data sets with date/time stamp
- Facilitate data transfer to printer, computer or USB drive
Benefits of Orion Star T920 Redox Titrator:
- Accurate, Reproducible Results: Automating the titration workflow enables analysis to be run using the same setup parameters and calculations every time.
- Fast Setup Time: Setup and save electrode, titrant and titration parameters once using methods.
- Prioritize Lab Throughput: Start the titration, and let the instrument run unattended.
- Minimal Cost and Downtime: Easily replace titrator parts to minimize maintenance downtime while long lasting electrodes may reduce the cost of ownership.
- Securely Document Test Results: View results live, in the summary table and within the 100-point data log.
- Applications Database: Tested and validated preprogrammed methods can be easily loaded onto your titrator via USB flash drive.
