MD 12 NT 隔膜泵
MD 12 NT 隔膜泵
MD 12 NT 隔膜泵是一款非常强劲的泵，用于非腐蚀气体的无油抽气。它的八泵头的三级结构同时具有大抽气速度和超高JX真空的优点。气路是由铝、不锈钢和经仔细挑选的塑料制成，应用范围广。高柔韧性的纤维增强的双层膜片采用氟橡胶（FKM）材质，真空性能好。八泵头的NT系列泵运行安静，表面整洁，易于整理。如同所有的VACUUBRAND的隔膜泵，运行过程中完全不需要油，在气路中也没有滑动部件。在常规操作时完全不会有摩擦，避免了如同涡旋泵或柱塞泵等会产生颗粒杂质的情况。 MD 12 NT 是针对非腐蚀性气体的持续无污染抽气的J佳选择。它们非常适合于物理和分析领域的应用。基于MD 12 NT 出色的JX真空使其在很多应用中可以很好地取代旋片泵，比如连接真空干燥箱、快速且有效地对粘稠介质进行抽气，尤其是用于大分子泵的前级泵等领域。其超大的抽速使其可用于较大的真空装置，具有高气载量。泵运行非常安静，振动非常低，使其非常适用于电子显微镜等精密仪器。因为它是无油真空泵，因此可避免向高真空腔体扩散油分子或反油。
