How It Is Used
The lamp is used to flame inoculating loops in microbiology, for simple distillations and for chemical tests in the field. Fill it only when it is unlit and dry the outside before lighting; put the flame out with the cap, which also stops the alcohol evaporating, and trim the charred end of the wick from time to time for a steady flame.
Frequently Asked Questions
