Dubois Raymond Keys Manufacturer, Suppliers and Exporter in India
Jaincolab Manufacturers is leading Dubois Raymond Keys Manufacturer,and supplier and Exporter in India
Dubois Raymond Keys from JaincoLab are make-and-break electrical switches that deliver a single, controlled stimulus, typically from an induction coil, to a nerve-muscle preparation so the resulting twitch or nerve response can be observed and recorded. The JA-DRK-2400 is a bench-mounted mechanical key with connecting terminals for wiring into an induction-coil circuit, used in physiology and electrophysiology practicals in teaching labs and medical and veterinary colleges.

What is a Dubois Raymond Key?
A Dubois Raymond Key is a make-and-break electrical switch used in classical electrophysiology teaching setups to deliver a single, controlled electrical stimulus — typically from an induction coil — to a nerve-muscle preparation, so that the resulting muscle twitch or nerve response can be observed and recorded. It is one of the standard apparatus items used alongside induction coils in physiology practicals on nerve and muscle excitability.
Selected Dubois Raymond Keys — Model Number and Specification Notes
JaincoLab lists the Dubois Raymond Key under product code JA-DRK-2400 in its current catalogue. The Dubois Raymond Key is supplied as a bench-mounted mechanical make-and-break key with connecting terminals for wiring into an induction-coil stimulus circuit.
Applications
| Setting | Application |
|---|---|
| Physiology teaching laboratories | Delivering a single controlled stimulus in nerve-muscle preparation experiments |
| Electrophysiology practicals | Demonstrating make-and-break stimulus circuits alongside an induction coil |
| Medical and veterinary colleges | Classical nerve-muscle physiology demonstrations |
Frequently Asked Questions
What is the difference between a Dubois Raymond Key and a Simple Key?
A Dubois Raymond Key is a specific make-and-break key historically used with induction coils in nerve-muscle physiology, while a Simple Key is a more basic circuit-make key used generally to control stimulus delivery in physiology experiment setups.
