Refrigerated centrifuges are at the forefront of laboratory equipment, enabling a wide range of applications from biology and chemistry to clinical diagnostics. These powerful instruments rely heavily on advanced cooling systems. In this article, we explore the significance of cooling systems in refrigerated centrifuges and delve into the latest technological advancements that are revolutionizing temperature control in centrifugation processes.
1. Preservation of Sample Integrity
Perhaps the most crucial role of cooling systems in refrigerated centrifuges is to maintain sample integrity. Many biological and chemical processes are extremely temperature sensitive. Without sufficient cooling, the heat created by high-speed centrifugation might cause sample degradation, denaturation, or change. Cooling systems ensure a steady and controlled environment within the centrifuge chamber, protecting sensitive samples’ molecular structures.
