1.First Steps
Welcome to Virtual laboratory.
Virtual laboratory is a cross-platform virtualization application. What does that mean? For
one thing, it runs on computers (Windows) and smart phones (IOS and Android).
Figure 1: The following screenshot shows how Vlabs, installed on an windows 10 computer.
Figure 2: The following screenshot shows how Vlabs, runs on a browser.

Figure 3: Display list of senior 2 chemistry experiments
In this User Manual, we are going to begin with a quick introduction to virtualization and
how to get your first virtual lab running with the easy-to-use Vlabs graphical user interface.
Subsequent chapters will go into much more detail covering more features, but fortunately, it
is not necessary to read the entire User Manual before you can use Vlabs.
1.1 Why is Vlabs Useful?
The techniques and features that Vlabs provides are useful in the following scenarios:
• Running multiple operating systems. Vlabs enables you to run virtual experiments for
senior two science courses. This way, you can run offline version on Windows OS, smart Phone
(IOS and Android) and Online version on a Windows, Linux or a Mac using installed internet
software (Browser).
• Easier software installations. User can use virtual laboratory offline or online version. For
example, installing an offline version, it requires setup (Exe) for windows and APK (android)
or IPA(IOS) for smart Phone.
For Online version, User can run Vlabs on any computers which is installed internet browser
software.
• Infrastructure consolidation. Help students to perform experiments more than once on their
own using Vlabs in smart classrooms or at home via computer or any other devices.

Enable students to perform many experiments that are difficult to perform in real laboratories
because of their risks.
1.2 Some Terminology
When dealing with virtualization, and also for understanding this documentation, it helps to
acquaint oneself with a bit of crucial terminology, especially the following
terms:
• Operating system (OS). This is the main software of the physical computer or Smart phone
on which Vlabs was installed. There are versions of Vlabs for Windows, IOS as well as
android and these versions don’t require internet connection (Offline version).
• Internet browser (browser). This is the software installed on the physical computer on
which Vlabs was ran. This version requires internet connection (Online version).
The system will be compatible with multitudes of web browsers supported HTML 5
including but not limited: Firefox, Safari, Chrome, Opera and Microsoft Edge.
• Virtual laboratory science (Vlabs). This is the special environment similar physical
science laboratory found in school that using computer graphics.
• WebGL (Web Graphics Library). is a JavaScript API for rendering high-performance
interactive 3D and 2D graphics within any compatible web browser without the use of plug-
ins. WebGL does so by introducing an API that closely conforms to OpenGL ES 2.0 that can
be used in HTML5 <canvas> elements. This conformance makes it possible for the API to take
advantage of hardware graphics acceleration provided by the user's device.
1.3Features Overview
The following is a brief outline of Virtual Lab main features:
• Portability. Virtual lab runs on a 64-bit or 32-bit windows operating systems. Supported
Mobile Operating Systems such as Android and IOS. The Virtual lab offline version requires
an windows OS on computer or Android, IOS for smart Phone while online version requires
browser software to be installed on any computer operating system.

• 3D virtualization. a virtual lab will support automatic adjustment of video resolutions,
seamless windows, accelerated 3D graphics and more.
• Audio. a virtual lab will support audio that use the computer's speakers for audio as well as
mobile device build in speaker.

Support for WebGL is present in Firefox 4+, Google Chrome 9+, Opera 12+, Safari 5.1+,
Internet Explorer 11+, and Microsoft Edge build 10240
2.Installing Vlabs
Vlabs comes in many different packages, and installation depends on your host OS. If you have
installed software before, installation should be straightforward. On each host platform, Vlabs
uses the installation method that is most common and easy to use for Offline version. If you
run into trouble or have special requirements you should use the Online version.
