摘要
设计一款用于土壤缓效钾测定的油浴辅助装置.此款辅助装置可以解决实验油浴加热过程中盛有土壤测试溶液的试管易倾倒、土壤测试溶液假沸腾、试管与高温油浴槽底部接触易产生爆裂、油液浪费、环境污染等问题.设备结构简单,使用简便,可满足学校实验室教学需要.
An oil-bath auxiliary device for determination of soil slowly available potassium is designed. The oil-bath auxiliary device not only can solve problems such as test tubes with soil test solution are easy to dump, the phenomenon of pseudo boiling in soil test solution, test tubes directly contact with high temperature oil-bath tank bottom are easy to burst, oil waste, environmental pollution in experimental oil-bath heating process, but also structure of the device is simple, easy to use, and to meet needs of school laboratory teaching.
