meter with the InMotion autosampler. The InMotion autosampler integrates with your pH meter to maximise throughput without sacrificing bench space. Create a flexible and efficient workflow by eliminating process order and transcription errors. Compliance and data security Security functions help support your workflow during calibration, data collection and data archiving. Built-in method creation ensures that analyses are performed with identical settings and parameters. LabX software adds more functionality and compliance, such as data and resource management and allows your benchtop pH meter to connect to other laboratory instruments.

ith two electrode inputs, both analogue and intelligent digital, the Metrohm 913 pH Meter can measure the pH value or ORP (redox potential) of two samples simultaneously – a capability that is ideal for mining laboratories. The Metrohm 914 pH/Conductometer can measure the ORP or pH value while also measuring conductivity, TDS, or salinity at the same time and in the same beaker. With the Metrohm 912 Conductometer you can measure conductivity and subsequently get a converted TDS / salinity reading. To ensure GLP, the sensor quality symbol on the display indicates if the sensor is still good for measurements and also provides a reminder of when the next calibration is due. To avoid 'finger 'errors the 'Expert' and 'Routine' levels provide additional security. The routine dialog restricts users to a limited scope of functions, while the
password-protected expert dialog allows authorised users to access the complete capabilities of the meter.

Even faster and easier titrations with Orion T
he Orion Star™ T900 automated titrators from Thermo Scientific™ simplify titrations by making it easier, more reliable, more reproducible and faster than manual titrations. Calibrate the electrode (sensor), standardise titrants and perform various types of potentiometric titrations using one of the four models presented in the series. The Orion Star T910 pH titrator, Orion Star T920 redox titrator, Orion Star T930 ion titrator and Orion Star T940 all-inone titrator will help to overcome problems of sample throughput or analytical complexity through automation of analysis. What differentiates the Orion Star T900 series titrators from other single
parameter instruments and automatic titrators is their simplicity; all of the setup procedures appear on the display in the form of easy-to-understand, sequential menus. Because the analysis is automated, each titration step is carried out consistently time after time, operator to operator, using a high precision burette that meets the ISO 8655 standard. Whether your analysis is acidity of juices, alkalinity of water, surfactants in shampoo, fluoride in drinking water or Vitamin C in juices, the Orion Star T900 series titrators offer a simple system to automate your measurements. The Orion Star T900 series combine Thermo Scientific’s core electrochemistry technology with a state-of-the-art reagent dispensing system to expand the number of ions and compounds that can be measured beyond direct electrode analysis, and offers dynamic process controls that adjust the titration to optimise analysis results. The system is paired with the premium Orion ROSS electrodes, which offer excellent stability, fast response, high accuracy and precision, long lifespan and minimal long-term drift.
These compact titrators are designed to: • Offer easy-to-use navigation from setup to live titration analysis to data transfer • Showcase titrations, on-screen instructions and help menus on the large colour graphic touchscreen display • Create and save up to ten userdefined methods • Save up to 100 titration data sets with date/time stamp • Facilitate data transfer to printer, computer or USB drive
