一种冷冻离心机的蒸发器
本技术属于实验室离心机,具体涉及一种冷冻离心机的蒸发器。
技术介绍
离心机是利用转头高速旋转产生的强大的离心力,加快液体中颗粒的沉降速度,把样品中不同沉降系数和浮力密度的物质进行分离的仪器,已广泛用于生命科学、医学、化学、环保等领域。由于在某些领域离心的样品需要在低温环境中进行,这时就需要用到冷冻离心机。冷冻离心机是利用蒸发器铜管传导制冷,发泡层保温,通过电器元件控制温度。目前冷冻离心机的蒸发器结构如图1至图3所示,包括安装在电机7上面底部设小孔的内套1,测温螺杆6从内套1的离心腔直接穿过小孔伸出外壳5,内套1的上端口与密封条8配合,铜管2盘绕在内套1的底部和周围,在铜管2和外壳5之间填充发泡层4,铜管表面3未喷涂。离心机转子高速旋转时,离心腔产生强大的内部气压,黏附在试管外壁的部分试剂会形成雾状小颗粒。由于铜管表面3没有喷涂,蒸发器的铜管2腐蚀主要集中在两个位置,一是由于内套1的上端口与密封条8配合处存在一定的间隙9,部分试剂会通过间隙9泄漏到发泡层4,发泡剂4渗水后直接溶化成粉状,导致蒸发器的铜管2腐蚀;二是内套1的底部在安装测温螺杆6 ...
