Melting point determination has never been so easy
M
ultiple methods such as melting point, boiling point, cloud point and slip melting point can be used to characterise or identify a substance and analyse its properties. Mettler Toledo‘s Excellence line of automated melting point and dropping point systems quickly and reliably determine thermal values and data. Using optical and calorimetric methods, these versatile systems measure a material’s physical properties and phase changes. Trust your results Never miss a measurement. The Excellence systems allow you to observe your measurements in real time via a video or replay it to verify your results. View intensity curves and results directly on the colour touch screen during or after the
experiment. Performance and precision can be verified by calibration using certified reference substances. Melting point systems The innovative melting point systems successfully determine the melting range, boiling point, slip melting point and cloud point, simply and efficiently on one device. Colour changes, the transparency point and the decomposition temperature can also be investigated. An unbeatable measurement principle and norm conformity assures exact and reliable results. Dropping point systems Dropping point systems determine dropping and softening points of physical properties of pitch, asphalt, polymers, resins, waxes and many more materials with fully automatic
operation and measuring two samples simultaneously, with just one click of the button. Standard compliant cups and measurement methods guarantee comparable results. LabX software LabX software enables rock solid quality control measurements by providing a comprehensive result overview, video storage and automatic result assessment. Re-analyse curves, organise comprehensive sample lists, generate customised reports and comply with regulatory needs.

QATM - hot mounting press for materialographic specimens
Microtrac’s SYNC particle size and shape analyser
Q
Combining laser diffraction and dynamic image analysis in one instrument
ATM's hot mounting press Qpress 50 is a modular machine used in metallography for the fast, simultaneous and independent mounting of different materialographic specimens. The modularity of the Qpress 50 allows adjustment of the machine configuration for varying sample sizes and throughputs, depending on customer requirements. Product advantages • Modular hot mounting press • Qpress 50-2: basic unit extendable with one additional pressing unit • Qpress 50-4: basic unit extendable with up to three additional pressing units • Fast mounting with low power consumption • Proven one-hand closure system with integrated dirt trap and suction nozzle • Dust Guard: removal of fine dust during filling of mould by connected vacuum cleaner
• •
7” touch display with innovative control software High flexibility due to preheating function, cooling modes, maintenance tasks and user account management features.
Features • Max number of pressing units: 2/4 (Qpress 50-2: up to 2) / (Qpress 50-4: up to 4) • Mould cylinder: Ø 25.2 - 50 mm (6 different sizes) • Closure system: Slide closure • Thermostat range: 20 – 200 deg Celsius • Heating time: Adjustable • Cooling time: Adjustable • Max pressure: 250 – 350 bar • Weight: ~ 50kgs.

ith the SYNC analyser, Microtrac MRB integrates its highly accurate tri-laser diffraction technology with its versatile image analysis capability to provide particle characterisation practitioners with a unique measuring experience. The patented synchronous measurement technology allows users to make both a
laser diffraction measurement and an image analysis measurement on a single sample, in the same sample cell at the same time. • One sample • One optical bench • One flow path • One sample cell • One analysis. This makes the SYNC ideally suited for routine QC applications. It also provides valuable information to researchers as they develop new materials and processes. The powerful software interface provides both particle size distribution information as well as a multitude of morphological parameters. The patented BLEND routine allows users to examine materials over a wide range of sizes from 0.01 microns to 4000 microns.
