一般描述

硅油用于制备温度在-50°C到+200°C范围内的油浴。
硅油通常用于研究实验室的油浴,用于需要在 -50°C 至 +200°C 范围内加热/回流温度的反应。与其他加热设备相比,油浴提供更均匀的热量。

应用

硅油在一项研究中被用作保护碳钢合金试样。硅油在NMR(核磁共振)分析中也被用作热源。

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
