Features
What is the principle of the melting point detection on a M-565 Melting Point instrument?
The melting process is monitored using a reflection mode. A camera captures the images and when no change occurs anymore, the melting point is reached.
What is the accuracy of a melting point determination?
The accuracy of the melting point determined using a heating rate of 0.5 °/min is +/- 0.3 °C for measurements up to 250 °C. For measurements at higher temperatures the accuracy linearly changes from +/- 0.3 °C at 250°C to +/- 0.5 °C at 400 °C.
How is a boiling point determined?
The boiling point is determined using the “Siwoloboff” method. The light beam illuminates the boiling point tube from the front and the camera records the image. The boiling point of the liquid has been reached when the flow of steam bubbles reaches a frequency of 0.6 Hz [Hertz].
Is it possible to measure the melting point of fats and waxes?
Fats and waxes are complex mixtures of several compounds. The melting point of waxes and fats is determined according to the slip melting point method. This can be done using the M-560 or M-565 Melting Point instrument (see the relevant application note).
What is the difference between the two measuring modes: according to Pharmacopeia or thermodynamic?
The determination according to Pharmacopeia measures the temperature at which the substance is completely melted. The thermodynamic method measures the temperature at which the sample starts to melt. Both melting points, the Pharmacopeia and the thermodynamic melting points, can be accurately determined by the BUCHI M-565.
Are the calibration and verification sets certified?
Yes, the substances are traceable to a primary standard (LGC). All the certificates are included with the calibration and verification set. The calibration of the M-565 is performed using the pharmacopeia mode.
Is it possible to export the results to a LIMS software?
Yes, it is possible with the M-565 using the Melting Point Monitor software.
