                                                                                                                                                                        •   玻璃反应釜主要是利用其双层的玻璃特点,我们可以再中间的夹层放置反应物料(有的叫反应溶媒),通过在常压或者负压的情况下进行搅拌反应。随着仪器行业的不断发展,越来越多的行业和企业运用到了玻璃反应釜,越来越多的企业加入到了玻璃反应釜发展并扩大,有双层玻璃反应釜、单层玻璃反应釜,三层玻璃反应釜,旋转蒸发仪、高低温一体循环机,循环水式多用真空泵、低温冷却液循环泵、油(水)浴锅,不锈钢集热式磁力搅拌器、超声波清洗器、电热鼓风干燥箱、智能玻璃恒温水浴、水槽、真空干燥箱,玻璃仪器气流烘干器、数显恒温电热套、直流恒速搅拌器、加热磁力搅拌器、数字温度控制仪、升降台等多种型号的教学仪器。玻璃反应釜通过双层反应釜夹层,注入恒温的(高温或低温)热溶液或冷却液,对反应釜内的物料进行恒温加热或制冷,并且可以提供搅拌。
                                                                                                                                                                            合理安装、正确操作设备是保证玻璃反应釜运行稳定的前提。
                                                                                                                                                                            一、注意保温。由于玻璃反应釜外套厚度较薄,因此保温性能较差。在使用高温、低温的过程中,用户均需要使用保温材料对釜体进行保温保护。也可选择带真空保温层的三层玻璃反应釜,这种结构适合作超低温反应。同时,用户需对反应釜的釜体以及导热介质循环的管子用保温材料包裹,注意保温层的厚度,以保证具有较好的保温效果。
                                                                                                                                                                            二、控温介质选择。一般而言,用户会根据所需要的反应温度。选择不用性质的控温介质,作为反应的热量传播介质。低温选择冰乙醇,常温选择水,高温则选择二甲基硅油。使用低温或者高温时,注意选择合适的介质,关键在于粘度。粘度太大介质,循环泵可能带不动,介质循环效果不好,无法达到需要的控温效果。贸然更换大功率的循环泵,压入介质压力过大,易损坏玻璃反应釜内衬,反应釜破裂。通常厂家都会根据自己的产品,配套相应的导热介质及加热制冷设备供选择。三晶玻璃仪器配的是二甲基硅油。
                                                                                                                                                                            三、存放位置需合理。玻璃反应釜作为反应放大试验装置,体积通常为50-200L,特定情况体积可以定制。由于釜体为玻璃材质,不锈钢为支架且架脚为脚轮,故存放位置需要慎重选择。脚轮虽然可以有脚扣固定,但是稳定性不强。因此,用户在存放过程中注意选择平坦的地方放置,并且保持机械搅拌中心与反应釜一致,否则易摇晃不稳,发生安全事故。另外,必须放置在通风位置好的场所。
