About This Simulation
Learn how to use a separating funnel to extract and dry a water soluble compound, such as caffeine from tea or coffee. Can you also predict the liquid phases in which the compound can be found?
Learning Objectives
- Describe the extraction process and its purpose, giving examples of its applications
- Explain the fundamentals of extraction theory and describe the process on molecular and operational levels
- Explain the use of drying agents and choose an appropriate drying agent for a variety of solvents
- Confidently predict which liquid layer is which and identify the layer your product is in
- Carry out step-by-step single and multiple extractions for a variety of solvents and combinations
- Competently demonstrate practical techniques required specifically for solvent extraction by following best practice
- Troubleshoot and rectify common problems encountered in solvent extraction protocol and rotary evaporation
- Competently carry out the work up steps that follow liquid-liquid extraction to isolate a product (filtration, solvent evaporation)

Learn More About This Simulation
Most students (and teachers!) can relate to caffeine's effect, either in tea or coffee. In the Liquid-Liquid Extraction simulation, you will learn how to extract caffeine as powder from its liquid form.
Master the separatory funnel
Learn the correct usage of a separatory funnel by first decanting a simple soda, removing any gas from the liquid perfection you shake, and venting the separatory funnel. This will teach you how to correctly set up the equipment while preparing you for the next steps. Next you’ll extract the caffeine, using an aqueous and organic phase to transfer the caffeine in multiple steps, from the aqueous coffee to dichloromethane.
Learn from your mistakes!
If you’ve ever made a mistake in the lab, this virtual lab has your back. Learn how to use a separatory funnel without fear of messing things up. In this simulation you have the freedom to make mistakes and learn from them as you go. And if you make a mess, don’t worry: Dr. One will be there to help clean up!
Use practice to learn theory
In liquid-liquid extractions the main focus is on using the separatory funnel. This is used here to separate caffeine from its aqueous phase into an organic phase and then dry it for a tiny amount of dried caffeine powder. Complete this task to help answer the question: Does a cup of tea contain more caffeine than a cup of coffee?

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."

Labster can be integrated within a school's LMS (Learning Management System), and students can access it like any other assignment in their LMS. If your Institution does not choose an LMS integration, students will log in to Labster's Course Manager once they have an account created. Your institution will decide the access method during the sales process.
Labster is only available for purchase by faculty and administration at academic institutions. To procure Labster, simply reach out to us on our website. Schedule a demo, book a meeting to discuss pricing, start a free trial, or simply fill out our contact form.
Labster simulations are created by real scientists and designed with unparalleled interactivity. Unlike point and click competitors, Labster simulations immerse students and encourage mastery through active learning.
Labster supports a wide range of courses at the high school and university level across fields in biology, chemistry and physics. Some simulations mimic lab procedures with high fidelity to train foundational skills, while others are meant to bring theory to life through interactive scenarios.
