Teltron Perrin Tube S
Teltron Perrin Tube S (Product Code: SLE/PHY/52) is an evacuated electron tube from the Teltron S series used to repeat Jean Perrin's experiment, which shows that cathode rays carry negative charge, in college and senior school physics laboratories. It helps students connect a visible electron beam with the idea of the electron as a charged particle, a key step in any unit on the discovery of the electron. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Perrin Tube Used For?
In Perrin's classic experiment, an electron beam is steered by a magnetic field into a charge collector linked to an electroscope or meter; the collector gains negative charge, showing that cathode rays are negatively charged particles rather than a form of light. The Teltron Perrin Tube S brings this historic result into the teaching laboratory as a clear physics demonstration for students in India studying atomic structure.
Electron tubes of this kind run at high voltages, so the tube should be set up and switched on by a teacher or technician, mounted in a suitable holder and connected with shrouded leads. Confirm the operating voltages, holder and coil requirements with us before ordering; we will send the specification with your quotation.

Frequently Asked Questions
What does the Teltron Perrin Tube S demonstrate?
The Teltron Perrin Tube S is used for Perrin's experiment, which shows that the electron beam, or cathode rays, carries negative charge. It is usually taught alongside other electron-beam experiments in a unit on the discovery of the electron.
What are the technical specifications of the Teltron Perrin Tube S?
Please ask us for the current specification sheet of the Teltron Perrin Tube S, including operating voltages and accessory requirements. We confirm these details with your quotation rather than list unverified figures on this page.
Which accessories does the Teltron Perrin Tube S need?
Teltron S-series tubes are mounted on the Teltron Tube Holder S, and electron-beam experiments generally need a high-voltage supply and often a pair of Helmholtz coils. Tell us what you already own and we will confirm what the Teltron Perrin Tube S set-up needs.
Can students operate the Teltron Perrin Tube S themselves?
The Teltron Perrin Tube S works at high voltages, so a teacher or lab technician should set it up and switch it on, with students observing and recording results. Always follow the operating instructions for the tube.
Who supplies the Teltron Perrin Tube S?
The Teltron Perrin Tube S is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India. Teltron is a third-party brand; the company sources the tube for schools, colleges and institutions in India and international markets.
What should a Teltron Perrin Tube S enquiry include?
For the Teltron Perrin Tube S, state the quantity, the S-series holder, coils and power supply you already have, and your delivery destination. Send the details through the contact page or the enquiry cart and we will reply with a specification and quotation.
