Learn More About This Simulation
In the Introductory lab, you will learn about acids and bases, the concepts of diffusion and osmosis, and blood typing. Try out this lab and become an expert in risk evaluation in the laboratory!
Learn about acids and bases
Your first task is to mix acid/base with water. Watch a 3D animation to see how it dissociates to produce [H3O+] or [OH-]. You will learn how to calculate pH depending on if it is a strong acid/base or a weak acid/base. You will be introduced to the concept of acid dissociation constant (Ka) and base dissociation constant (Kb).
Diffusion and osmosis
Diffusion and osmosis are two fundamental concepts in biotechnology that are also important in daily life. In the Introductory lab, you will learn the difference between diffusion and osmosis. Observe under the microscope how cells adapt to hypotonic or hypertonic environments based on the principle of osmosis. You will learn that environments are dynamic by e.g. seeing that cells that are already swollen can be reverted back to normal by adding hypertonic solution.
Conduct a blood test experiment
In the introductory lab, you will also conduct a blood type test experiment. You will be presented with a patient that is in desperate need of a blood transfusion. To help the patient, you will first learn about the different blood type groups (both ABO and Rh) and the consequences of incompatible blood transfusions, and then you will use a typical blood type test card to determine the blood group. By observing the results, whether the sample clots or not, you will be able to draw a conclusion and determine the blood group.
Will you be able to save the patient with your newly acquired knowledge?

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.
