Tips For Choosing High Quality Laboratory Blood Centrifuge

Before analyzing blood, urine, and sputum, a clinical laboratory uses a centrifuge to ‘spin’ them. Yes, that’s exactly what this device does in order to separate lipoproteins, biological components, and DNA fragments specifically for quantitative analysis. There are many different kinds of centrifuges to choose from thes days. To get the most out of centrifugation, you have to make the right choice, especially when it comes to blood centrifuge for laboratory. Before choosing a centrifuge, learn a little bit more on how to choose them right.

Speed Requirements

The centrifuge spins in order to isolate a certain components from a fluid sample. RPMs show how fast the rotor of a centrifuge turns and RCF measures the force or speed that the sample is moved. As the speed goes up, the denser materials move away from the axis of rotation. And you have to remember that different applications need varying speed and force requirements. So the first step is to find a centrifuge that fits your needs and testing applications.

Rotor Requirements

In addition to meeting the speed and force requirements, it is also very important to choose a rotor that is right for your application. It should also be within the speed range of the centrifuge. During centrifugation, the rotors hold the sample tubes in place. 

  • Swinging Bucket Rotors. For this rotor, the sample tubes are placed in buckets as they move around. As the speed of the rotor goes up, the buckets spin at a more acute angle, getting closer to a straight line. This is the most receommended choice for low-speed, high-capacity applications.
  • Fixed Angle Rotors. A fixed-angle rotor on the other hand has tubes facing outward at a 45-degree angle. This is the most recommended for quickly processing small samples because they can spin up to three or four times faster than bucket rotors.

Refrigeration Requiremen

Refrigerated centrifuges work best for applications that need precise temperature control while being processed inside the machine. Refrigerated centrifuges keep operating temperatures low and steady. They are sealed, and move at high RPMs. This way, they make the rotors less hot. On the other hand, a vented centrifuge can be used if there’s no need for precise temperature control. This is usually more preferred because they are cheaper and takes up less space. 

Tube Size Frequently Used

When choosing a centrifuge, the capacity that it can take at every process is very important. Each centrifuge has a certain number of sample tubes that it can hold at a time. Choosing a centrifuge will be so much easier if you know how many tubes you will need and what size they usually are.
