沸腾管
沸腾管(Boiling Tube)又称为大试管，是一种在实验室常见的玻璃容器，它的大小、长度和容量均比一般试管大。与一般试管不一样，沸腾管能承受本生灯的高热而不破裂。
它的开口比一般试管为大，目的是让溶液有足够的空间沸腾。普通试管的管口太狭窄，溶液受热时，没有足够的空间让生成的气体离开溶液表面，最终可能令试管爆裂。因为形状和试管完全相同，沸腾管很多时候被当作容量较大的试管使用。
沸腾管一般使用能承受高温的派热克斯玻璃制成。

Boiling tube 沸腾管
A boiling tube is a small cylindrical vessel used to strongly heat substances in the flame of a Bunsen burner. A boiling tube is essentially a scaled-up test tube, being about 50% larger.
They are designed to be wide enough to allow substances to boil violently as opposed to a test tube, which is too narrow; a boiling liquid can explode out of the end of test tubes when they are heated, as there is no room for bubbles of gas to escape independently of the surrounding liquid. This phenomenon is called Bumping.
