Erlenmeyer flask can be heated up with a Bunsen burner.
Explanation:
A bunsen burner is a lab equipment that is used to heat things that aren't made up of anything flammable. The things that are to be heated with a bunsen burner are instruments of material like borosilicate like pyrex.
An Erlenmeyer flask that also goes by the names conical flask or even a titration flask can withstand a large amount of heat from the bunsen burner as it's made up of very thick and resistant glass. A graduated cylinder will not be able to withstand that amount of heat and a plastic pipette is sure to melt.
