Plastic Test Tubes
Plastic test tubes are often used with economy in mind, when the contents are neither corrosive nor will be heated. Otherwise, glass test tubes would be used.
The appropriate content stored in plastic test tubes can be transferred to a slide and placed under a microscope, or added to another test tube for mixture. As such, an entire experiment could take place within a single test tube. The singular or mixed content of two or more other test tubes could all be combined in one; there the reaction in the experiment could be observed.
In such a mixture of glass and plastic test tubes it is very important that the limitations concerning heat and corrosion be kept in mind when conducting such an experiment. Otherwise, a loss of valuable time, or of critical content itself could void any financial savings from purchasing a set or sets of plastic test tubes.
Another use is storage of specimens and biological samples. A common example would be samples of blood types i.e. Type A, Type B etc; then transfered to a slide or study under a microscope for purity or any abnormalities.
Plastic test tubes are a staple in most laboratories in high schools, colleges, universities and in corporate labs. They are a critical component to any fully equipped laboratory, due to their relatively small, perfectly designed physical structure for their purpose. Identification and storage of their contents is easily maintained over long periods of time.
That “perfect” structure being tube-like, with straight sidewalls from top to bottom. That prevents virtually any loss of the content while being poured. Though most plastic test tubes are clear plastic, a large variety of colored plastic is available. This is sometimes preferred for ease of identification. A transparent tint is used so the contents would still be easily visible.
