Is centrifuge A medical device?
The CF-10 Pro-Micro-Centrifuge is a Class 1 Medical Device that is supplied with a fixed angle rotor for 12 x 1.5/2.0 mL micro-centrifuge tubes. It is a compact unit and offers quiet operation with a safety electronic lid system. The rotor also has a bio-containment rotor lid ensuring securely contained samples.
How does a medical centrifuge work?
A centrifuge works by using the principle of sedimentation: Under the influence of gravitational force (g-force), substances separate according to their density. Here, particles are concentrated as a pellet at the bottom of the centrifuge tube and separated from the remaining solution, called supernatant.
What is a medical centrifuge?
A centrifuge is a device used to separate mixtures made up of parts with different densities. In the medical field, centrifuges are mainly used in laboratories to prepare samples for analysis. For example, a centrifuge is used to separate plasma from blood. There are different types of centrifuges on the market.
What are centrifugal devices?
Centrifugal devices can replace traditional separation techniques, such as column chromatography, preparative electrophoresis, alcohol or salt precipitation, dialysis, and gradient centrifugation, when performing the following: Protein or nucleic acid concentration. Desalting. Virus concentration or removal.
How much does a blood centrifuge cost?
Average Centrifuge Cost Benchtop – $1,000 to $5,000. Large Capacity / High Speed – $10,000 to $25,000. Ultracentrifuge – $10,000 to $50,000.

What items can be used in a centrifuge?
In research and clinical laboratories, centrifuges are often used for cell, organelle, virus, protein, and nucleic acid purification. An example of centrifuge use in a clinical setting is for the separation of whole blood components.
What types of materials can a centrifuge separate out?
Centrifugation separates the components of heterogeneous mixtures. These include liquids in liquids, solids in liquids, and solids and liquids in gases. Centrifugation uses centrifugal force to move dense components to the outside of the container. This causes the solid to settle more rapidly and completely.
How do you collect serum?
After collection of the whole blood, allow the blood to clot by leaving it undisturbed at room temperature. This usually takes 15–30 minutes. Remove the clot by centrifuging at 1,000–2,000 x g for 10 minutes in a refrigerated centrifuge. The resulting supernatant is designated serum.
