在澳大利亚牙科协会2012年发布的感染控制指南（ADA Guidelines for Infection Control）中，对使用超声清洗器有以下注意事项：
Items must be free of visible soil before being placed in an ultrasonic cleaner. In addition:
• lids, tank, gaskets and strainers must be cleaned daily;
• water must be de-gassed before use;（必须使用脱气水）
• cleaning fluid must be changed a minimum of twice daily (or when it appears heavily contaminated);
• an aluminium foil test (or another approved performance test) must be performed daily and the result recorded;（每天必须做铝箔试验（或其他认可的性能试验）并记录结果。
the lid must be closed during operation (to avoid dispersal of aerosols);
• instruments must be completely submerged in fluid; and
• no part of the operator’s fingers or hands is permitted to be immersed in the fluid during operation of the cleaner.
您知道脱气水、铝箔试验这二个名词吗？它们的意义何在？请您参与讨论！

1、把水或乙酸乙酯放置在烧瓶中，烧瓶口用胶塞塞住，在搅拌下通入氮气半小时，注意用一个针头排空即可的简单脱气 剂。 若是对气体非常敏感的溶剂，则放置在Schlenk瓶中用液氮冷却——抽真空——水浴解冻，反复3到4次即可满足任何实验要求。
