技术领域technical field
本实用新型涉及一种实验室用滴定实验系统，其属于化学实验装置领域。The utility model relates to a titration experiment system for a laboratory, which belongs to the field of chemical experiment devices.
背景技术Background technique
目前，一般实验室滴定分析采用的是人工滴定法，它是根据指示剂的颜色变化指示滴定终点，然后目测标准溶液消耗体积，计算分析结果。在滴定过程中，左手握滴定管，右手拿住锥形瓶，边滴加溶液，边摇动锥形瓶。在滴定实验所需时间较长时，右手会感到疲劳、麻木，稍有不慎会有溶液溅出，而且还容易发生锥形瓶的瓶口碰在滴定管的管口上而造成的事故。At present, the general laboratory titration analysis adopts the manual titration method, which indicates the titration end point according to the color change of the indicator, and then visually measures the consumed volume of the standard solution to calculate the analysis result. During the titration process, hold the burette with your left hand and the Erlenmeyer flask with your right hand, and shake the Erlenmeyer flask while adding the solution dropwise. When the titration experiment takes a long time, the right hand will feel tired and numb, and the solution will splash out if you are not careful, and accidents caused by the mouth of the Erlenmeyer flask hitting the mouth of the burette are prone to occur.
