Virtual Lab 6.2.2

Discover the micro world with this virtual microscope


  • Constantly updated samples
  • High definition images
  • 3D rendering, when available


  • Many file are too big and very slow to download
  • Unusual navigation into the images
  • Fixed zoom
  • 3D rendering often not available


I was always fascinated by the science laboratory hours at school, when we had to use microscopes to literally discover new words, and test chemical compounds and the ways they react with eachother.

I also remember how cool mercury was and how our incautious teacher had let us played with our hands in it, despite its toxicity. If you want to discover more about the micro-universe but you don't want to have the hassle of slides, drops of blood or samples of skins, give VirtualLab a try.

This application is funded by NASA and it is a digital microscope with many specimens you can easily download from the main page. You don't have to install anything, just click the thumbnail that attracts you most and the program take care of downloading it and make it available for you.

Among the specimens available there are human blood cells, penicillin, pyrite, meteorite, lunar dust, yeast, dog liver and human kidney samples.

Be careful though as some of the files are really big, more than 150MB and it will take ages to download them. This is because the images are really detailed and you can zoom in more than 150,000X.

For some images then, you can also select a portion and have a 3D rendering in another window.

Looking at the downsides I found the technique you have to use to navigate through pictures pretty unusual, and I didn't like the fixed zoom.

In fact, it is not possible to zoom in freely on an image, as there are just four fixed zoom levels you can choose from.

VirtualLab is a fascinating program with which you can efficiently discover the micro world thanks to 84 high-definitions.

The Virtual Microscope is a NASA-funded project that provides simulated scientific instrumentation for students and researchers worldwide as part of NASA's Virtual Laboratory initiative.

This site serves as home base for the Imaging Technology Group's contributions to that project—namely virtual microscopes and the multi-dimensional, high-resolution image datasets they view.

Currently we provide 90 samples totaling over 62 gigapixels of image data. The Virtual Microscope, which is available for free download supports functionality from electron, light, and scanning probe microscopes, datasets for these instruments, training materials to learn more about microscopy, and other related tools.
