In the centrifugation process, heat is produced by the friction with the air in the rotor and centrifuge chamber. Heat can affect the centrifugation cycle. However, some processes that use centrifugation will require a specific temperature. Similar applications and processes will typically require a heated centrifuge.
A heated centrifuge works the same way as the typical centrifuge. While centrifuges come in various sizes (with benchtop types considered the most common), a heated centrifuge stands out for its temperature setting controls. Heated centrifuges are considered the top choice for use in industrial and research laboratories.
For instance, the Hettich ROTOFIX 46 H is one type with a vast range of accessories designed for routine applications. However, it can also be used for special centrifugal tasks. The Hettich ROTOFIX 46 H is primarily used to test non-medicinal specimens and can accommodate a wide range of special tubes including the ASTM (American Society for Testing Materials) tubes.
When a Heated Centrifuge is Used
Some of the common applications for heated centrifuges include:
- Carrying out ASTM tests
- Doing standardised crude oil test procedures
- Identifying sulphuric acid content on chrome baths
- Organometallic and coordination chemistry procedures (a centrifuge has the capacity to hold Schlenk tubes. Specimens placed in Schlenk tubes can be separated through centrifugation
Unlike other centrifuges that are typically used in clinical and medical laboratory diagnostics, heated centrifuges are not intended to be used for medical analysis. It does not fall under the IVD Directive standards for clinical centrifuges (which are used in Europe and other countries).
