Visual Melting Point Apparatus (MR-Vis)

The Visual Melting Point Apparatus allows the researcher to get an indication of the compound or element’s purity. The entire operations of the melting point apparatus are controlled by the central processing unit and the printer provides the necessary prints of calibration and accurate, precision and repeatable results.


Labindia Melting Point has a micro-controller for temperature control, temperature range, heating rates, cooling time, etc. It also comes with state-of-the-art design and remarkable features. With guaranteed accurate results and superior quality functioning, Lab India’s Visual Melting Point Apparatus supersedes the other market players. 


One of the analytical techniques applied to the characterization of pure chemicals and pharmaceutical drugs (from raw material, to scale-up, to finished form) is the melting point (MP) determination. Carefully choosing the MP determination procedure is important for generating certifiable results for chemical quality control (QC) and quality assurance (QA).It is used in Analytical QC/QA laboratories, pharmaceutical labs and chemical analysis.
