Dubois Raymond Key
Product Code : JA-DRK-2400
The Dubois Raymond Key (SKU JA-DRK-2400) is the Du Bois-Reymond short-circuiting key used in experimental physiology to control when stimuli from an induction coil reach a nerve-muscle preparation. With the key closed the current is short-circuited, and opening it lets the stimulus pass to the electrodes. The key is mounted on a vulcanite base with a table clamp, and JaincoLab manufactures it for physiology and pharmacology teaching laboratories.
