General description

Silicone oil is typically used for oil baths in research labs for reactions that require heating/reflux temperatures in the range of -50°C to +200°C. Oil baths provide more uniform heat in comparison to other heating devices.
Silicone oil is useful for the preparation of oil baths having a temperature in the range of -50°C to +200°C.

Application

Silicone oil has been used for the protection of carbon steel alloy samples in a study. Silicone oil has also been used as a heat reservoir during NMR (Nuclear Magnetic Resonance) analysis.

Most established NMR thermometers rely on temperature-dependent chemical shift differences measured from samples that are either neat or concentrated solutions (e.g. ethylene glycol, methanol). These are unsuitable for modern cryoprobes on account of strong radiation damping resulting from the high

We have recently demonstrated strong nuclear deformation of SaOs-2 osteosarcoma cells on poly-L-lactic acid (PLLA) micropillar substrates. In the present study, we first demonstrated that chemical and mechanical properties of the micropillar substrates have no dominant effect on deformation. However

Radial head fractures without associated bony or ligamentous injury can be safely treated with internal fixation, if possible, or arthroplasty if nonreconstructable. However, nonreconstructable radial head fractures in association with elbow dislocation and/or ligamentous injury in the elbow or forearm
