Introduction to Tabletop Refrigerated Centrifuge
A tabletop refrigerated centrifuge is a compact and efficient instrument widely used in laboratories for separating components of liquid samples. Unlike traditional centrifuges, these devices incorporate a refrigeration system, ensuring that heat-sensitive samples, such as enzymes, proteins, or nucleic acids, are maintained at a stable temperature during high-speed centrifugation. Their small footprint makes them ideal for laboratories with limited bench space, while offering high performance comparable to larger centrifuge models.
How Tabletop Refrigerated Centrifuge Works
tabletop refrigerated centrifuge operate using centrifugal force generated by spinning rotors at high speeds. Samples contained in tubes are subjected to this force, causing denser particles to move outward and settle at the bottom while lighter components remain above.
The refrigeration system plays a crucial role in preserving the integrity of delicate biological or chemical samples. Temperature-controlled operation prevents thermal degradation, ensuring the quality and reliability of experimental results. Many modern units also feature programmable controls, allowing precise regulation of speed, duration, and temperature.
