Cathode Ray Tube Manufacturer,Supplier and Exporter in India
Product Code : EL-ELA-5264
Jlab Export is a leading Cathode Ray Tube Manufacturer,and suppliers in India
Cathode Ray Tube (code EL-ELA-5264) is a vacuum tube in which an image is formed where an electron beam strikes a phosphorescent surface, used in physics and chemistry teaching labs to show cathode rays and how an electron beam behaves. The same principle lay behind older television and computer display screens. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Cathode Ray Tube Used For?
Cathode rays are streams of electrons, and experiments with tubes of this kind led J. J. Thomson to the electron and its charge-to-mass ratio. In the lab the glowing spot on the phosphorescent screen lets students see the beam directly: bring a bar magnet near the tube or apply a voltage across deflecting plates and the spot moves, showing that the beam carries negative charge and is bent by electric and magnetic fields. The tube supports class 11 chemistry lessons on the structure of the atom, class 12 physics on moving charges and the e/m experiment, and explains how a cathode ray oscilloscope draws its trace. A CRT runs from a high-voltage supply and is made of evacuated glass, so make connections only with the supply switched off, mount the tube in a stand, and never knock or drop it.
Frequently Asked Questions
What can students observe with this tube?
The spot or image formed where the electron beam hits the phosphorescent surface, and how that spot moves when a magnet or an electric field is applied.
Are a stand and power supply included?
They are not part of this listing. A cathode ray tube stand is listed separately, and the operating supply should be confirmed with JLab for your set-up.
Who manufactures this cathode ray tube?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics lab apparatus manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Its tubes and electron-physics apparatus are produced at its own works, so colleges, schools, dealers and importers buy from the maker itself and repeat orders come from the same source. JLab’s GSTIN is 06AADCJ9848D1ZE and its Legal Entity Identifier is 549300DTGS77DGYD6N03. JLab exports worldwide and ships to buyers in every region — for example Uzbekistan in Central Asia, Guatemala in Central America and the Caribbean, Bolivia in South America, Namibia in Southern Africa and Mauritius in East Africa.
