Science Test Tubes

Science test tubes are often used to hold and secure rather small amounts of chemicals, in either liquid or solid form. A measure of the content can be removed from the test tube and be placed under a microscope, mixed with the content of another test tube, or be completely removed for placement elsewhere as part of an experiment.

The other main use of science test tubes has nothing to do with any experimentation, but rather simply as the preferred method of storage for biological samples. Often these would be blood samples, which then could be examined and studied through a microscope for biological content and purity.

Science test tubes are a critical component in even the most basic high school laboratory, to the most elaborate and sophisticated labs in corporations, colleges and universities. They are absolutely indispensable, thanks to their very compact and efficient physical structure, ease of storage and relatively low cost compared to most other laboratory furnishings.

That extremely practical and efficient "structure" is tube-like, with sidewalls that are straight from bottom to top which keeps loss of contents to a minimum when pouring. Though most science test tubes are clear making it very easy to view the contents, some do have a color tint for easy identification and are still rather transparent.

If the science test tubes are to be used for storage and mixture in chemistry, it would most likely be constructed of glass to counter corrosive chemicals and high temperatures. If the test tubes are to be used for storing biological material, they are probably constructed of less expensive clear plastic.
