About the Melting Point Analysis: Pure or impure? Virtual Lab

About this simulation

Melting organic solids: it’s the same principle as when ice melts! In this simulation, you will be introduced to the melting point analysis technique and apply it to organic syntheses you would carry out in the lab. Uncover one of the simplest and most informative techniques for indicating substance purity and learn how to determine whether you synthesized a pure substance using the recorded data and graphs.

Sample preparation

Get first-hand virtual lab experience preparing a sample for melting point analysis. Start by learning the correct protocol for sample loading, including how to choose the right tube for the machine and amount of sample required. Tips and tricks like these will help ensure maximum accuracy and precision for the sample measurement.

Test your creativity!

One of the great things about being in a virtual lab is that you can break apart the machine. Uncover the key components behind a functioning melting point machine to understand the conditions required to melt your sample. You’ll even get the chance to build your own functional melting point machine from common laboratory equipment!

Analyze substance purity graphs

Get a deeper look at what is happening with your sample inside the machine using our high tech hologram! Observe the different stages of melting: Moistening Point, Sintering Point, Meniscus Point and Clear Point. Learn about the states of matter when the solid sample reaches each of these stages and relate them to the plotted points on a substance purity graph, also known as the heat curve for a solid compound.
