14 Analytical Instrumentation High-end circulators for challenging temperature applications


With the MAGIO series, Julabo is expanding its product portfolio of high-end bridge mounted circulators, refrigerated and heating circulators - naturally all in the usual premium quality. The circulators operate in a working temperature range from -50°C to +300°C and with a heating capacity of up to 3 kW. Excellent heating/cooling performance guarantees very short heat-up and cool-down times.


With an extremely powerful pressure/suction pump with performance values up to 31 l/min or 0.92 bar (pressure) and -0.4 bar (suction), the MAGIO series offers the strongest pump in its class and is therefore perfectly suited for challenging external temperature tasks. To ensure maximum resistance against chemical substances, all wetted parts are made from stainless steel.


Modern interfaces make easy remote control and practical data management possible as well as allowing integration into process structures. All MAGIO units come with integrated Pt100 connection, USB interface, RS232 and Ethernet. Analog interfaces are optionally available as accessories. Upon customer request, JULABO can equip any refrigerated and heating circulators of the MAGIO series with the OPC UA communication interface.


OPC UA stands for ‘Open Platform Communications Unifi ed Architecture’ and is a standardised communication standard between machines (M2M) or between machines and higher-level systems. The open interface standard is independent of the machine or application manufacturer and is one of the most important communication standards for Industry 4.0 and the IoT.


In order to speak a common ‘language’, so-called ‘companion specifi cations’ are constantly being developed and published for a wide variety of unit types. This means that the data to be exchanged in an industry (e.g. laboratory devices) is standardised and all information is thus made available in the same form across all units and manufacturers. The specifi cations are developed in cooperation between the OPC Foundation, various professional associations (e.g. SPECTARIS for optics, photonics, analysis and medical technology) and machine manufacturers.

email: 62564pr@reply-direct.com Smartphone app for pH, conductivity, and oxygen measurement


Endress+Hauser presents the Memobase Pro app, an ideal companion to the popular Liquiline Mobile CML18 handheld meter. Combining high-quality measurement technology with cutting-edge app capabilities, it delivers an unparalleled digital experience for measuring, calibrating, and documenting.


Launched about three years ago, the Liquiline Mobile CML18 handheld meter gained widespread acclaim for its practicality and versatility in measuring pH, conductivity, oxygen, and ORP. With its compact design, it fi ts into any shirt pocket, catering to both laboratory and production processes.


The revolutionary Memobase Pro app enables users to connect and operate two Liquiline Mobile CML18 devices simultaneously through a secure Bluetooth connection. Leveraging the smartphone display for handheld meter operation enhances user-friendliness and intuitiveness. Memobase Pro features dashboards and visualisations, allowing seamless switching between trend curves and tabular displays for measurements and associated samples. With the app functioning even when the smartphone is in the pocket, users can concentrate fully on their work during measurement and calibration. Additionally, the app can be operated directly from the handheld meter, facilitating the saving and documentation of measured values.

The Liquiline Mobile CML18, utilising Memosens technology, boasts the most widely used sensor technology globally for liquid analysis. Equipped with an integrated microprocessor, sensors with Memosens technology convert all signals into a robust digital format, ensuring immunity to moisture and environmental infl uences. Consistency between laboratory and process measurement data is maintained by connecting the same sensor types to the handheld meter, preventing deviations due to different measurement technologies.


For dependable measured values, regular sensor calibrations, especially for pH sensors, are crucial. The Memobase Pro app guides users through the calibration process and seamlessly documents all calibrations, including reference solutions used. An elegant solution for importing reference solution data involves a QR code on bottles that users can scan with their smartphone camera, enabling swift data importation.

Refractometer application for urea content in AdBlue® AdBlue®


is a diesel exhaust fl uid


used to reduce nitrogen oxide emissions from heavy industrial and commercial diesel engines. The fl uid is a mixture of deionized water and the main active ingredient, high-purity urea. Measuring the quantity of urea in AdBlue® involves refractometry and spectrophotometry and this is outlined in Kyoto Electronic Manufacturing’s application document found at KEM Search, their dedicated application database. Briefl y, a refractive index calibration curve is produced after measuring a sample and urea standards using a KEM RA-600 series refractometer, with the fi nal value obtained after correcting for biuret content (measured by spectrophotometry). KEM’s RA-600 series benchtop refractometers are perfect for measuring AdBlue® as they are not only highly accurate, but they also achieve fast temperature stabilization over a large range, feature an anti-volatilization fi tting, are easy to clean, have fl exible data visualization and export options, and have a host of other attractive features. KEM also has other products relevant to measuring AdBlue®including potentiometric titrators (alkalinity), density meters (density), and furthermore, operates ISO/IEC 17025 and ISO 17034-compliant refractive index and density liquid standard testing and production laboratories.
