What Is the Spare Glass Bulb Used For?
Hero’s engine, described by Hero of Alexandria, is one of the earliest machines to turn heat into motion. Water is boiled inside the engine’s glass vessel, the steam escapes through angled jets, and the reaction to the escaping steam turns the vessel on its axis. The demonstration illustrates energy transformation from thermal to kinetic energy and Newton’s third law of motion, topics met in class 9 science and class 11 physics.
What to Specify When Ordering
- Number of spare bulbs required.
- Complete Hero engines, if you also need whole units — a separate item that can be quoted on the same enquiry.
- Delivery location and any packing or labelling instructions.
Frequently Asked Questions
What is the Spare Glass Bulb for?
It is a replacement glass bulb for Hero’s engine, so a school or college can repair the apparatus instead of replacing it.
What does Hero’s engine demonstrate?
How heat energy is converted into kinetic energy, and Newton’s third law: steam forced out of the jets pushes back on the vessel and makes it rotate.
What information is needed for an export quotation?
Send the number of bulbs, the destination country and port or city, your delivery terms (for example FOB or CIF), any packing or labelling needs and a tender reference if there is one.
Who manufactures the Spare Glass Bulb?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of physics demonstration apparatus and laboratory glassware in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Spare bulbs are produced at JLab’s own works rather than sourced from a trader, so schools, colleges, dealers and importers buy them factory-direct and can come back to the maker for further spares. The company is registered as a manufacturing enterprise under MSME Udyam registration UDYAM-HR-01-0003849 and holds Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Canada in North America, Jamaica in Central America and the Caribbean, Congo in Central Africa, Bhutan in South Asia and Vanuatu in Oceania. For tenders, see the JLab lab tenders page.
