Learn More About This Simulation
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.

For Science Programs Providing a Learning Advantage
North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

A Labster virtual lab is an interactive, multimedia assignment that students access right from their computers. Many Labster virtual labs prepare students for success in college by introducing foundational knowledge using multimedia visualizations that make it easier to understand complex concepts. Other Labster virtual labs prepare learners for careers in STEM labs by giving them realistic practice on lab techniques and procedures.
Labster’s virtual lab simulations are created by scientists and designed to maximize engagement and interactivity. Unlike watching a video or reading a textbook, Labster virtual labs are interactive. To make progress, students must think critically and solve a real-world problem. We believe that learning by doing makes STEM stick.
Yes, Labster is compatible with all major LMS (Learning Management Systems) including Blackboard, Canvas, D2L, Moodle, and many others. Students can access Labster like any other assignment. If your institution does not choose an LMS integration, students will log into Labster’s Course Manager once they have an account created. Your institution will decide which is the best access method.
Labster is available for purchase by instructors, faculty, and administrators at education institutions. Purchasing our starter package, Labster Explorer, can be done using a credit card if you are located in the USA, Canada, or Mexico. If you are outside of North America or are choosing a higher plan, please speak with a Labster sales representative. Compare plans.
Labster supports a wide range of STEM courses at the high school, college, and university level across fields in biology, chemistry, physics, and health sciences. You can identify topics for your courses by searching our Content Catalog.
