MD 4C NT 化学隔膜泵
MD 4C NT 化学隔膜泵
三级化学隔膜泵是针对腐蚀性气体和蒸汽的一种持续的、无油抽气的优秀解决方案，可以满足许多有难度的要求。这种三级结构同时具有大抽气速度和超高JX真空的优点。MD 4C NT的所有与被抽介质接触的部件都是由抗化学腐蚀的氟材料构成。经广泛验证的PTFE“三明治”夹层结构的膜片稳定性更高，延长了操作寿命。MD 4C NT配备有气镇阀时，可用于抽取易冷凝的蒸汽，甚至可用于高沸点的溶剂，这是因为它具有非常好的JX真空（即使使用气镇时）。全新的NT系列进一步增进了性能参数，更易于维修，对蒸汽有更好的耐受性。 三级化学隔膜泵是针对高真空需求的腐蚀性气体或蒸汽应用的J佳选择。主要的应用是与旋转蒸发仪、干燥箱等实验室仪器连用。MD 4C NT与干燥箱或干胶机连用时，在抽取其中大量蒸汽方面有卓越的表现。该款泵同时也作为一款基础泵，是一系列完整的性能可靠的化学真空系统的核心部件，主要用于大型的实验室应用。
