Centrifuges like the clinical centrifuge are typically used in laboratories to separate fluids based on density. In clinical and research laboratories, centrifuges are used for virus, protein, cell, organelle, and nucleic acid purification. Clinical centrifuges are used in the separation of whole blood components.
Clinical centrifuges are mostly present in diagnostic centers since they typically carry out routine separation activities. Aside from separating blood components like red blood cells, white blood cells, and plasma, centrifuges are also used to extract sediment from urine.
There are also cases when centrifuges are used to separate DNA fragments as well as other cell components and separate lipoproteins to determine their measurements. Since clinical centrifuges are to separate particles, they are low-speed. They also come with specific functions and features that are designed for medical use.
Stand Out Features of Clinical Centrifuges
Some of the stand out features of clinical centrifuges include:
- Compact design and build that is ideal for the analysis of serum and blood samples
- They come with wide range of fixed-angle and swinging bucket type of rotors to suit user requirements
- Has a low-speed range suitable for blood separation at about 4000 to 5000 rpm
- Air cooled option that operated at room temperature or refrigerated version with temperature control
- Built in safety features
Since clinical centrifuges are created to handle delicate specimens, they come with built-in safeguards like a protective lid to ensure there is no unwanted spillage. It is recommended that centrifuges are cleaned regularly to avoid contaminating the samples.
It is also a requirement to balance the tubes when using a centrifuge. This is done by placing the tubes opposite each other. When there is an imbalance, the results of the separation process can get affected.
Questions to Ask When Buying a Centrifuge
It is ideal to pick a centrifuge that’s suited for a specific application. Before purchasing a centrifuge, ask yourself the following questions:
- What sample volumes will I be working with?
- Are the samples temperature sensitive?
- Will I use the centrifuge to process blood banking or clinical samples?
- How much laboratory space do I have available?
- What is the maximum g-force speed the centrifuge can generate?
