他还发明了早期的本生灯装置，几乎所有的实验室都使用它作为最便利的热源。
He also invented the earliest form of the device that was to become the Bunsen burner, which is used almost universally in science laboratories as a convenient source of heat.
在每一次本生灯灯火焰燃烧10秒钟移开后，没有任何一个试片被火焰点燃超过10秒钟。
The specimens may not burn with flaming combustion for more than 10 seconds after either application of the test flame.

German chemist who pioneered in spectrum analysis and codiscovered the elements casium and rubidium. he introduced the bunsen burner in1855.
在最近的一次旅行中，我尝试了一下，非常有趣，不过需要手巧一点，很像以前在学校里上的化学课，只是没有实验用的本生灯(Bunsenburner)。
I tried this for a trip recently and it was quite fun to do, if a bit fiddly, much like an old chemistry class at school, minus the Bunsen burner.
