Separating Blood and Platelets: How the Process is Done

Separating Blood and Platelets: How the Process is Done

The blood separation process is considered one of the most meticulous procedures done in clinical laboratories. The procedure makes use of a blood centrifuge and is carried out using a procedure known as centrifugation. Thus making blood centrifuges a common equipment in hospitals, clinics, and medical diagnostic centers.

Blood centrifuges come in various brands and models. One of the most trusted blood centrifuge is the Hettich Roto Silenta 630 RS. Floor standing and heavy duty, it is known for its rapid and efficient centrifugation of blood bags. The Hettich Roto Silenta 630 RS is also capable of spinning up to 12 blood bags each run.

The Process of Separating Blood and Platelets

To separate platelets from a blood donation, the blood is kept at a room temperature, processed, and stored within eight hours after it was donated. The blood is sent to the laboratory where it is spun down and separated into various parts. Red blood cells, plasma and platelets each have different storage conditions, medical uses, and shelf life.

Automated Platelet Donation

During a platelet donation (the process is called apheresis), the whole blood is removed into satellite bags and sterile tubing. A blood centrifuge spins the blood to separate the red blood cells, platelets, and plasma. As the blood is separated, the heavier red cells will sink to the bottom and will be given back to you.
