Adjust adjusting device of chromatography column chromatography velocity of flow

一种调节层析柱色谱流速的调节装置

Abstract

本实用新型属于实验设备技术领域,具体涉及一种调节层析柱色谱流速的调节装置。该装置包括固定卡、设于固定卡上的旋塞、与旋塞通过输液管连接的储液罐。本实用新型结构较为简单,制备方便,具有较好的实用价值,具体优点表现为:通过储液罐的设置可以避免频繁向层析柱添加流动相的操作繁琐的弊端;而通过调节储液罐的高度即可实现流动相的流速调节,因而操作便捷;另外,在层析柱长时间不使用时,可将层析柱旋塞和本实用新型装置的旋塞同时关闭,避免层析柱中流动相的挥发而导致层析柱的损坏,延长层析柱的使用寿命。
The utility model belongs to the technical field of the experimental facilities, concretely relates to adjust adjusting device of chromatography column chromatography velocity of flow. The device includes the fixing clip, locate cock on the fixing clip, pass through the liquid storage pot that the transfer line is connected with the cock. The utility model discloses the structure is comparatively simple, and the preparation is convenient, has better practical value, and concrete advantage shows as: the complex operation's of flowing phase drawback can be avoided frequently adding to the chromatography column through setting up of liquid storage pot, and can realize the stream speed adjusting festival of flowing phase therefore simple operation through the height of adjusting the liquid storage pot, in addition, when the chromatography column does not use for a long time, can with the chromatography column cock with the utility model discloses the cock of device is closed simultaneously, avoids volatilizing of flowing phase in the chromatography column and results in the damage of chromatography column, the life of extension chromatography column.
