Inverting an evacuated tube, often used in laboratory settings, allows for the collection of a sample in the opposite orientation, which can be crucial for specific tests. This process can help ensure that the sample is properly mixed with any additives or anticoagulants present in the tube. Additionally, it can facilitate the separation of components, such as blood cells from plasma, by allowing gravity to assist in the sedimentation process. Overall, inverting the tube is an important step to maintain sample integrity and accuracy in testing.
An evacuated tube is a sealed glass or metal tube from which air has been removed to create a vacuum, minimizing heat transfer through conduction and convection. This design is commonly used in solar collectors and thermal insulation applications, where it enhances energy efficiency by reducing heat loss. The vacuum inside the tube acts as an insulating barrier, allowing for effective heat retention or transfer depending on its application.

What does the evacuation system
Inverting a tube of blood will not prevent it clotting. Only an anticoagulant will do this, the different coloured tops on blood samples refer to the different anticoagulants or lack thereof inside the tubes. Inverting the tube is done to mix blood samples that have settled gently inverting the tube 6-10 times is enough to mix the blood. Inverting the tube more than this or doing it too violently could trigger clotting even in a sample containing an anticoagulant.

Both time and temperature can decrease the vacuum draw of an evacuated tube. Hence the provided expiration dates and storage temperature of tubes. The vacuum of a tube will decrease if it is too old or if stored at a colder temperature than recommended.

The yellow evacuated tubes are for blood cultures.
It needs to be 100% full as the light blue tube.

The color-topped evacuated tube typically used for the collection of blood for electrolyte testing is a green-top tube, which contains heparin as an anticoagulant. Heparin prevents clotting and ensures accurate testing of electrolyte levels in the blood.
