5)用温水浴解冻溶剂,直到溶剂刚刚融化。能够观察到气泡从溶液中产生。不要晃动液体。注意:让冷冻溶剂自己解冻或者只用水融化冷冻溶剂底部,都可能导致容器破裂。 6)用冷却液代替水浴,冻结溶剂。 7)重复步骤3)-7)直到解冻无气体产生。此过程至少三次。 8)填充氮气密封瓶。 溶剂可以使用。

将封管里的溶液用液氮冻成固体,抽真空,充氮气,解冻,这个过程重复两三次,彻底除去体系中的残留氧气 天山明月 欲脱气的溶液放在Schlenk管中,用液氮冷冻成固体,抽真空。温热使液体融化,在此过程中液体中少量残留气体就会排出。重新冷冻,抽真空。再温热使融...重复三次,保证体系脱气完全。 fandream 通常用于无氧反应除...
B1. Hazards: The most significant hazard presented by the freeze-pump-thaw technique is the shattering of the glass vessel. To minimize the chances of accidental vessel rupture, only vessels made from thick-walled glass designed to resist pressure changes should be used. This method is commonly...

在食品加工行业中,three pump-freeze–thaw cycle (三泵冻结-解冻循环) 技术被广泛应用于食品保鲜和储存方面。由于该技术可以快速、高效地将食品冷冻,并在需要时迅速解冻,因而被认为是一种非常有效的食品处理方法。 传统的食物冷藏和解冻过程可能会导致部分营养成分流失或质地变差。然而,three pump-freeze–thaw cycle...
