Which standards must laboratory test tubes meet?
The use of laboratory samples is an essential part of many analyzes and investigations. See for yourself what they should excel at and why.
Which standards must laboratory test tubes meet?
The results obtained in the testing laboratories must ensure the highest level of reliability and relevance. To make this possible, accurate and specially calibrated devices with the latest measurement technology must be used. However, just as important as carrying out the necessary examination is proper sampling and securing the material taken. It would not be possible without the appropriate laboratory accessories.
What function do laboratory test tubes fulfill?
Efficient laboratory work requires the use of different types of Laboratory equipment for the preparation, collection and measurement of various substances - both reagents and comparison material or test samples. Test tubes with screw caps are one of the elements without which it is difficult to imagine the smooth running of the individual procedures. They enable efficient protection against Falsification of results by external factors that could penetrate the extracted material. At the same time, they also offer protection against possible effects of the sample on laboratory personnel or other ongoing investigations, e.g. B. in situations where Bacteria, viruses or fungal spores could be present in the sample to be examined. Necessary descriptions are also placed on the test tubes, e.g. B. Time of collection, location, type of substance or examinations to be carried out. To eliminate the risk of contamination of the sample distorting the result, the test tubes must be sterile and at the same time damage resistant be. These requirements are met by test tubes made of plastic - polystyrene or polypropylene - and by stoppers or screw caps for test tubes, which are made from the same raw materials.
Why do plastic test tubes perform so well in laboratories?
The plastic test tubes are resistant to mechanical damage, and the possibility of closing them with a stopper or a screw cap further reduces the risks associated with their use. Dropping or knocking over a test tube made of suitable plastic does not automatically mean that its contents are lost. The materials used - polypropylene or polystyrene - are insensitive to the substances contained in the samples taken, do not react chemically with the compounds of which they are composed and there is no risk that they will influence the result. The highest quality test tubes are made by NOEX, a manufacturer of laboratory equipment and accessories for the medical, veterinary and food industries.
