一套由圆锥花瓶(Erlenmeyer花瓶)和两孔橡胶停放器组成,其中插入了酒精温度计和封闭玻璃管。 这些物品以这种方式组装,以发现液体的沸点. 首先,酒瓶的底部会被加热并用有金属网状物的三脚架来固定,因为加热。 液体会蒸发并升入玻璃管中,温度计会记录出液体被煮取的温度. 圆锥花瓶由化学家埃米尔·埃伦迈尔于1861年发明,以圆锥形和窄颈而出名. 它用来通过旋动来混合物质,并给物质加热到高而并非强烈的温度. 圆底花瓶蒸馏用于高温. 这些瓶子对经典的实验室取暖器有很大的改进,因为它们的窄颈限制了液体的流失,混合过程中有溢出的危险,以及由挥发性化学反应而来的危险. 它们也可以用棉花或阻塞器来密封。 这部作品取自萨拉戈萨Andrés Manjón小学的一批教学和实验室用品.
