You generally need something to prevent the solution from bumping. You might be able to get by with boiling chips, as long as you don't let the
solution cool down below the boiling point and then heat it again.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

For homogeneous reaction mixtures stirring during reflux is obsolete. For heterogeneous mixtures, stirring is practically always needed, reflux or no
reflux.
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)
