The utility model provides a test tube rack for benzoic acid preparation, which comprises a rack plate, a sliding side and a positioning side are arranged on the rack plate, a slide groove is arranged on the sliding side, a number of sliding rods are arranged between the two slide grooves, a number of pillars are arranged on the sliding rod, pillars on the adjacent two sliding rods are arranged alternately, and an X-shaped groove is arranged at the end of the pillar A number of positioning buckles are arranged on the positioning side, the section of the positioning buckle is rectangular, the positioning buckle is provided with a limit protrusion, a spring is arranged between the limit protrusion and the positioning side, a number of through holes are arranged on the shelf, a heating layer is provided with a heating layer, a heating layer is provided with a hanging ear, and a heating wire and a fan are arranged in the heating layer. Advantages of the application are: when the distance between the two sliding rods is large, the test tube is inserted downward into the pillar, and the pillar is used for drying the test tube. When the distance between the two sliding rods is small, the test tube is clamped upside down between the pillars to keep the test tube in use. After the experiment, the angle of the pillar can be adjusted, the test tube is hung on the pillar, and the heating layer is used to make the test tube dry. Test tubes are quickly dried.

一种苯甲酸制备用试管架
本技术涉及有机化学基础实验器材,特别是指一种苯甲酸制备用试管架。
技术介绍
试管架是用来放置、晾干试管用的化学实验室的最基本的实验仪器。传统的试管架中附有相应数目的小柱和小孔,小孔的可将试管竖放待用或以便继续观察反应的进行,小柱的可将洗净试管倒放,以便晾干。但是在实验结束后,往往晾干的试管比较多,实验时,往往待用的试管比价多,而小孔和小柱的数量固定有限,不能很好调节不同情况下的供需关系。
技术实现思路
本技术提出一种苯甲酸制备用试管架,解决了传统试管架不能很好调节不同情况下的供需关系的问题。本技术的技术方案是这样实现的:一种苯甲酸制备用试管架,包括架板,所述的架板上设有滑动侧边和定位侧边,滑动侧边上设有滑槽,两个滑槽之间设有若干滑动杆,滑动杆上设有若干支柱,相邻两个滑动杆上的支柱交错设置,支柱的端部设有X形槽,定位侧边上设有若干与X形槽配合的定位扣,定位扣的截面为矩形,定位扣上设有限位凸起,限位凸起与定位侧边之间设有弹簧,架板上设有若干通孔,架板的下部设有加热层,加热层上设有挂耳,加热层内设有加热丝和风扇。所述的定位侧边分为上下两块,定位扣卡在上下 ...
