天平是分析化学工作最主要的常用仪器之一。在定量分析基础课实验中,要对学生进行分析天平基本操作的严格训练,要求达到了解构造原理,操作正确熟练,称量准确快速。采用双盘或单盘电光机械天平都可以满足上述要求。近两年,我们从北京光学仪器厂购进一部分DT-100型单盘分析天平,经在定量分析实验课中使用,效果良好。我们体会到单盘天平具有下列优点:
Balance is one of the most common and commonly used instruments in analytical chemistry. In the quantitative analysis of the basic course of experiments, students should conduct rigorous training to analyze the basic operation of the balance, required to understand the principle of construction, the operation is correct and skilled, accurate and rapid weighing. The use of double disk or single disk electro-optical mechanical balance can meet the above requirements. In the past two years, we purchased part of DT-100 type single-plate analytical balances from Beijing Optical Instrument Factory and used them well in the quantitative analysis experiment class. We appreciate the single disc balance has the following advantages:
