*Students performing an electrochemical titration,
c.1963 (66k). The students are using the Leeds & Northrup
K-3 potentiometer
and Galvanometer. Note
also the Epply standard cell
in the forground. The Rudolph
Research Polarimeter can be seen on the table behind the
students. All of this equipment was purchased with the construction
of the new Science building (now Science A) c. 1960. |

*Analytical Chemistry Balance
Room, c. 1963 (50k). The students are looking at the workings
of one of the Mettler balances
purchased with new construction money c. 1960. (The young man
is Greg Bowman, who later became a member of the Chemistry Department
faculty.) Note the Christian Becker chain
balance and Christian Becker density balance in the background. |
