Forensic Drug Testing Simulated Immunoassay Kit for 15 Groups Build to Order used both in galvanic-cell construction

used both in galvanic-cell construction and as the photoemitter in classic photoelectric-effect demonstrations

sized for fine-print reading and convex-lens image-formation work in introductory optics

pink-dotted at one end of each magnet to flag the matching pole and supplied with steel keepers between lessons

four 16-mm inner holes

Illustrates liquid-density changes with temperature using a weighted 75mm hollow copper sphere that floats in 15°C water and sinks as the water warms to 30°C
