An experiment in micro chemistry, Chemistry 102, in the spring of 1939. The close up photograph shows a hand holding tweezers which in turn hold a small chemical boat as it is about to be inserted into a small electrified chamber. A voltage meter and…
A chemistry student at work in a laboratory. Dressed in a white lab coat, the student is standing before a distillation apparatus with a wall of reagents on shelves behind the equipment.
G. F. Hanna, a graduate student in the Department of Chemistry and a research fellow of the Agricultural Experiment Station, demonstrating the refrigerated bath in the refrigerated laboratory. The room was maintained at a temperature just above…
Frank Janssen, a graduate student in chemistry, with a Craig Liquid Extraction Apparatus. This apparatus, invented by Dr. Lyman Craig, an Iowa State alumnus, was widely used for separating medicinal and other biologically important materials. It…
G. F. Hanna, a graduate student in the Department of Chemistry and a research fellow of the Agricultural Experiment Station, showing the refrigerated super centrifuge along with the refrigerated bath. The room was maintained at a temperature just…
A female student in a white lab coat using a Worburg apparatus. The Worburg apparatus was widely used in biochemical and biological research for measuring rates of reaction in which gases are involved. The student is noting readings in a lab record…
A technician hand-making a piece of laboratory glassware with a torch for heat. Holding a piece of glass rod stock in the torch with one hand, the technician is modifying the glass tube by touching it with a glass rod in the flame. Glass lab ware…
Two technicians in the glass lab of the Chemistry Department. One technician is working with a torch and tubes of glass at a worktable, on which are a lighter, glass tubes, rubber stoppers and various tools.The other technician is standing in the…
Professor F. E. Brown observing a chemistry student in the lab. The student is using a dropper to add liquid to a test tube. Three other students are working in the background.
Jim Weiher at the dry box (a shielded laboratory chemical containment hood), which was used to perform chemical operations in a controlled atmosphere. Weiher is seated, with his arms inserted through portals into the inner chamber which can be viewed…
