Product Information

Think this classic of modern physics is out of reach in your classroom? Think again. With this apparatus you can accurately determine the elementary charge of the electron and demonstrate quantization. And, its user-friendly features let you focus on results, not set-up and clean-up. Assembly takes just seconds and actually becomes part of the instructive process: students attach the two main components guided by the case image, a schematic of the experiment. The latex microsphere suspension, used instead of oil, means clean-up takes only moments with distilled water. Its whole-plate reversible polarity electrode chamber provides a completely uniform field, while a high intensity LED light source brilliantly illuminates particles and is fully adjustable for beam focus and background contrast. Short depth-of-field viewing scope with reticle allows coarse and fine focus, with scanning of the particle cloud for individual particle selection. Because the base unit is integrated with a 500V power supply, there's no need to buy and arrange a power supply, leads, voltmeter, probes, or ringstand; meaning your time and budget both go farther. Experiment manual included.
