Discover Our 25 New Virtual Science Experiments and Features

Last Updated on June 20, 2022 by Mostafa

New virtual science experiments are launched on our website to provide you, schools and higher education, with an all-in-one portal of 3D science simulations!

Doing online virtual science experiments in a virtual lab simulation allows students to learn from just about anywhere, home, library, or virtual computer labs. In the traditional labs, teachers spends a great deal of time demonstrating the procedure and the theoretical background of the experiments, But online virtual science experiments are faster and they also give students a feeling of being more comfortable while conducting the  experiments. 

About 25 new experiments are added to the List of 3D Science Simulations in the fields of chemistry, physics, and biology.

We’ve been working hard to develop PraxiLabs to enrich our users’ experiences. But our ultimate goal is to make  the interactive virtual science experiments science labs accessible, easy to use, and affordable for educational institutions and schools.

In order to provide you with an all-in-one portal of 3D interactive virtual science simulation, we’ve just added dozens of brand new online virtual science experiments to PraxiLabs catalog. From biology to chemistry & physics.

19 New Online Virtual Science Experiments in Biology

PraxiLabs new enriching experiments in biology cover topics in biochemistry (Proteomics, Pharmacology, Toxicology) and Molecular Biology (Genetics, Microbiology, Biochemistry, Bioenergetics) like:

Adherent Cell Culturing using Mammalian Cell Lines

In Adherent Cell Culturing Virtual Lab simulation, you will understand how cells are cultured, propagated, subcultured, and frozen in liquid nitrogen for long term storage. In Vitro Cell Culturing is a very important protocol for preparing cells needed for all subsequent In Vitro Cytotoxicity and Genotoxicity assays.

By the end of this experiment, the student will be able to: 

 Handle the consumables needed and the required instruments  in cell culturing process.

Accurately  follow the Aseptic Techniques of cell culturing.

 Follow and work  the general important safety guidance which is necessary for Good Laboratory Practice (GLP).

  Dissolve cells from Liquid Nitrogen and then seed them in cell culture flasks.

Harvest cells, check the confluence, and count them by the microscope.

 Store the cells for long term using liquid nitrogen.  

 Scale up the cultured cells to set up further experiments.

Cultivation of Virus in Chick Embryo


The main purpose of virus cultivation experiment is:

to learn how to identify and isolate viruses in clinical samples.

to do research on viral replication, structure and detect the effects on host cell.

know the steps of virus preparation for vaccine production process.

And by the end of the experiment, you will:

  • Become proficient at performing the viral cultivation consistently and accurately.
  •  learn the essential concepts of virology.

Building a Model for Catalytic Interactions

     Building a Model for Catalytic Interactions


In the virtual lab of this experiment you will learn to demonstrate the importance of the presence of enzymes in biochemical reactions showing their absence may lead to slowing down the rate of these reactions or even preventing them from taking place.


The concept is explained through this experiment by studying the effect of an acidic medium inside the stomach (represented by seven up here) on food (represented by biscuits). Then, the digestion of food (biscuits) is monitored in order to understand the necessity of the digestive enzymes for the vital process inside living organisms.

And By the end of the experiment, you will know the answer to the investigative questions: Why do biochemical reactions require catalysts? What are the expected results of the experiment in the absence of enzymes in the term of speeding up or slowing down the rate of the reactions or even their occurrence?
