New M3000 Melting Point Meter
The M3000 is a new Semi-automatic Melting Point Meter from A.KRÜSS Optronic. It has a built-in RS-232 interface and can measure melting points of up to three different sample types from 30C to 360C. Learn More…
Total Mercury in Edible Oils
Edible and Essential Oils are widely used throughout the world in food products, beverages, cosmetics, etc. Mercury, a toxic heavy metal, is present in these oils in low to high concentrations. Typical analysis requires the use of tedious and time-consuming acid digestions that often lead to errors and inadequate results. The NIC Model PE-1000 Mercury Analyzer accurately and precisely measures the total mercury in oils with unprecedented automation and ease.
New Circulating Water Bath
The new PT80 Circulating Water Bath from A.KRÜSS Optronic is very compact and has a temperature range of 5C to 80C with accuracy of +/- 0.1C. Ideal for potentiometry, viscometry, conductivity measurements, & titrations. Learn More..
The Model SG1800 Spectronometer-Goniometer from A.KRÜSS Optronic is ideal for the exact measurement of optical data on prisms. It can also be used as a spectroscope. Learn More…
Evaluating the Quality of Oils
Three of the most important quality control methods for oil quality include the measurement of refractive index (RI), optical rotation, and the density of oil. A.KRÜSS Optronic offers advanced tools for each of these measurements. In our study, each of these three measurements were completed on a wide variety of edible and essential oils, including measurements at various temperatures. Learn More…
Measuring the Quality of Nitrogen Generator Output
Nitrogen generators are widely used for providing the massive volumes of nitrogen gas required by many mass spectrometers being used today. In our own efforts to simply determine the relative quality of the nitrogen being supplied by our nitrogen generator, we stumbled onto an easy and quite accurate method for making these measurements…the MAT1200 from A.KRÜSS Optronic is typically used for testing the modified atmospheres of packaged foods, but in this case, we decided to use it for determining the nitrogen quality from our generator.
