PRODUCT FEATURES 产品特征：
Cold trap is a small-sized ultra lowtemperature cryogenic equipment,suitable for Parylene vacuum coated
cold trap,biochemical petroleum experiment, low temperature liquid bath, gas trap, drugfreeze-drying and so on. There are two types of cold traps according to theirapplication method: pot type cold trap and bar type cold trap. The size of thecold trap, refrigeration mode can be customized according to the needs of theusers.
冷阱是一种小型超低温设备，适用于对二甲苯真空包覆冷阱、生化石油实验、低温液浴、气体捕集、药物冷冻干燥等。根据其应用方法，冷阱有两种类型：锅式冷阱和棒状冷阱。冷藏室的尺寸，制冷方式可以根据用户的需要定制。
Utilize compressor refrigeration to makethe temperature in the pot chamber drop below -95℃, ( thistemperaturecan be adjusted according to the actual application). Under low temperaturecondition, when the gas passes through the pot chamber, partial highcondensation point compositions will be turned into liquid or even solid andstored in the pot chamber, the low condensation point compositions will continueto flow through the pipelines, so as to achieve the purpose of gas compositionseparation.
利用压缩机制冷，使锅室温度降至-95℃以下(此温度可根据实际应用情况调整)。在低温条件下，当气体通过罐室时，部分高凝点成分转化为液体甚至固体，储存在罐室中，低凝点成分继续流过管道，达到气体成分分离的目的。
In vacuum applications, a cold trap is adevice that condenses all vapors except the permanent gases into a liquid orsolid. The most common objective is to prevent vapors being evacuated from anexperiment from entering a vacuum pump where they would condense andcontaminate it. Particularly large cold traps are necessary when removing largeamounts of liquid as in freeze drying.
在真空应用中，冷阱是将除气体以外的所有蒸汽凝结成液体或固体的装置。见的目标是防止从实验中抽出来的蒸气进入真空泵，在那里他们会凝结并污染它。特别是大的冷阱是必要的，当清除大量的液体，如在冷冻干燥。
Pumps that use oil either as their workingfluid (diffusion pumps), or as their lubricant (mechanical rotary pumps), areoften the sources of contamination in vacuum systems. Placing a cold trap atthe mouth of such a pump greatly lowers the risk that oil vapors will backstream into the cavity.
使用油作为工作液(扩散泵)或润滑剂(机械旋转泵)的泵通常是真空系统中的污染源。在这样的泵口放置一个冷阱，大大降低了油蒸气回流进入空腔的风险。
Care should be taken when using a cold trapnot to condense liquid oxygen (a light blue liquid) into the cold trap. Liquidoxygen is potentially explosive, and this is especially true if the trap hasbeen used to trap solvent. Liquid oxygen can be condensed into a cold trap if apump has sucked air through the trap when the trap is very cold.
使用冷阱时应注意不要将液氧(淡蓝色液体)浓缩到冷阱中。液氧可能是爆炸性的，尤其是如果这个捕集器被用来捕集溶剂的话。液氧可以凝结成一个冷阱，如果一个泵已经通过陷阱吸入空气时，陷阱是非常冷的。
