Direct linkXu, Xicheng; Suganuma, Yoshinori; Dhirani, Al-Amin – Journal of Chemical Education, 2020
Lock-in amplifiers (LIAs) are commonly used in chemistry laboratories to improve noise-to-signal ratios. Constructing and testing a suitably designed LIA provide undergraduate students with an excellent opportunity to learn about theory, construction, and applications of LIA. In particular, students can learn about time-dependent behavior and…

Goach, Audra L.; Croslow, Seth; McLaughlin, Kyle; Distin, Steve – Journal of Chemical Education, 2022
The correct use of micropipettes has been investigated in an undergraduate, introductory lab experiment intended for chemistry and biology majors. This lab experiment involves the use of micropipettes for accurately mixing, transferring, and applying a specific amount of dye to a cotton bandana. The data resulting from this experiment is a color…
