Test Tubes

Test Tubes in Clinical Chemistry 

When it comes to clinical chemistry, test tubes are part of the basic laboratory equipment. They not only serve to mix and store sample material, such as blood or urine, but they are also used for pipetting and centrifugation. Whether they are being used for determining haemoglobin in capillary blood or for a simple liquor examination, test tubes offer diverse applications in clinical chemistry. 

Test Tubes and Test Tube Racks

Since test tubes have a rounded base, they cannot be simply stood up like Erlenmeyer flasks or other lab bottles. During use, they must be stored in a test tube rack. The test tube rack can simultaneously hold multiple test tubes and prevent them from tipping over. These test tube racks are often made of plastic, wood or metal and are available in various sizes. 

Properly Cleaning Test Tubes

Because of their tall, thin shape, test tubes require special cleaning tools to be properly cleaned which are known as test tube brushes. These reusable brushes have a long handle with a loop for hanging and are equipped with flexible bristles in the lower area which can easily remove impurities.

Typically, the lower end of the test tube brush features a cluster of bristles with which the base can be easily cleaned. After the general cleaning, the test tubes can then be professionally reprocessed in an automatic cleaner or disinfection machine. 

Stability Through High-Quality Glass

In order to guarantee the longevity of test tubes, high-quality glass, such as Fiolax or soda lime glass, is used in production. This should assure that the test tubes withstand as many reprocessing cycles as possible and do not break during use.
