技术领域technical field

本发明涉及一种容器密封装置，尤其是一种易于提取挥发性很强的溶剂的容器密封装置。The invention relates to a container sealing device, in particular to a container sealing device which is easy to extract highly volatile solvent.

背景技术Background technique

在化学分析工作中往往会遇到挥发性很强的化学溶剂，溶剂的挥发会造成试剂的损失和引起浓度的改变，给分析工作带来误差。这类化学药剂通常用普通的密封瓶盖结合密封垫储存，使用时需要采用取样针多次穿刺密封垫提取，经过多次穿刺后，密封垫上残留的的针孔会导致易挥发溶剂的缓慢泄漏，重新打开瓶盖更换密封垫，也会造成易挥发溶剂的挥发损失，引起容器内溶液浓度的改变。In chemical analysis work, we often encounter highly volatile chemical solvents. The volatilization of solvents will cause loss of reagents and changes in concentration, which will bring errors to analysis work. This type of chemical agent is usually stored with an ordinary sealed bottle cap combined with a sealing gasket. When using it, a sampling needle needs to be used to puncture the sealing gasket multiple times to extract. After multiple punctures, the remaining pinholes on the sealing gasket will cause the slow leakage of volatile solvents. , Re-opening the bottle cap to replace the sealing gasket will also cause volatilization loss of volatile solvents and cause changes in the concentration of the solution in the container.
