vacutainer

A vacutainer is a specialized tube used by healthcare professionals to collect blood samples. It’s designed with a vacuum inside, which creates a slight suction when the tube is pierced with a needle. This suction automatically pulls the right amount of blood into the tube, making the process quick and efficient. Vacutainers often have additives inside to preserve or prepare the blood for specific tests. They are widely used because they ensure a safe, sterile, and controlled way to obtain and handle blood samples for diagnostic purposes.
