Petrochemical LMS  Issue 2 | 2014  27 Determining Dropping Points M ettler Toledo’s dropping point systems automatically determine dropping and softening points of pitch, asphalt, polymers, resins, waxes, paraffin and binders. Dropping and softening points are used mainly in quality control. The Excellence line of dropping point systems offers superior performance and ergonomics, and is compliant with ASTM, AOCS, DIN and ISO standards. Standard compliant cups and measurement methods guarantee comparable measurement results. Simultaneous analysis of two samples delivers the mean value and the difference of the single results. The colour touchscreen allows one finger operation and provides clear information Competitive Ultrasonic Cleaners L abotec has a new range of Scientech Ultrasonic cleaners for effectively cleaning micro-particles from a wide scope of products. All tanks are manufactured from long-lasting, 304-stainless steel and equipped with variable frequency and power settings. They also have an extremely good price to performance ratio. The Scientech Ultrasonic cleaners are especially useful for cleaning any precision instrument part using their ultrasonic vibrations. These cleaning units can be used for emulsification, mixing and the removal of oxidation from surfaces. There is a choice of five different sizes of cleaners, ranging from 2.5 to 25l. All models operate with a temperature range of ambient to a maximum of 80°C. They units are all supplied with baskets and lids as a standard, and all of the units above the 4l capacity are fitted with drain taps for easy maintenance. ⚛ Labotec Tel: 011 315 5434 Fax: 011 315-5882 Email: [email protected] for the user. Just one click is all that is needed to start the measurement. When completed, the instrument signals the end of the measurement with an acoustic tone and displays the measured temperatures. One can also achieve high throughput by simultaneously determining two samples in one run. The samples are pre-melted and filled into the cups sitting in the sample preparation tool, which is preheated in a dry oven. One can perform different mea­sure­ment tasks rapidly and efficiently by working with up to 60 stored methods. Economic single-use cups and heating without water or oil baths eliminate the need for tedious cleaning. Visual camera observation and digital image analysis guarantee that the d ­ eterminations are reliable. The high resolution colour videos recorded during the measurement can be repeatedly replayed on the instrument. This allows one to check unexpected results by visually reviewing measurements. ⚛ Microsep Contact: Rudy Maliepaard Tel: 011-553‑2300 Email: [email protected]
