Apparatus Convection In Liquid
Apparatus Convection In Liquid (Product Code: SLE/PHY/08) is a rectangular loop of glass tubing used to show convection currents circulating in water in school and college physics and science classes. The 350 × 210 mm rectangle is made from 22 mm glass tubing, so a few potassium permanganate crystals trace the moving water clearly when one lower corner is gently heated. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Convection Tube Used For?
Fill the rectangle with water, clamp it upright in a retort stand and drop a few potassium permanganate crystals into the tube. When a small flame warms one lower corner, the heated water expands, becomes less dense and rises up that side, while cooler water sinks down the opposite side to replace it, and the purple colour shows the whole loop circulating. The demonstration links directly to sea breezes, hot-water systems and the way a pan of water heats from the bottom.
Use only a gentle flame on one corner, never the whole base, so that a single clear current forms. Warm the glass gradually to avoid thermal shock, use just a few crystals so the colour stays traceable, and let the water cool before emptying and rinsing the tube. It gives any heat energy science kit a vivid, reusable convection demonstration for middle and secondary classes.
OEM Manufacturer
The Apparatus Convection In Liquid is produced by Jain Scientific Equipments Private Limited, better known by its trading name ScienceLab, which acts as the OEM (original equipment manufacturer) for its heat and physics apparatus. It is manufactured at the company’s own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, dealers and importers; enquiries about repeat orders or replacement glass go straight to the maker, so just ask us.
The company is a registered MSME (Udyam UDYAM-HR-01-0003714), and its export orders are shipped under Importer-Exporter Code AAECJ8618A (DGFT). See our company profile for more.

Frequently Asked Questions
What size is the Apparatus Convection In Liquid?
The Apparatus Convection In Liquid is a 350 × 210 mm rectangle made from 22 mm glass tubing. In use it is mounted vertically in a retort stand, so check that your stand and clamp can hold a frame of that size securely.
How do you show convection currents with this apparatus?
To use the Apparatus Convection In Liquid, fill it with water, mount it vertically, drop a few potassium permanganate crystals into the tube and gently heat one lower corner. The coloured water rises on the heated side and circulates around the rectangle.
Is potassium permanganate included with the Apparatus Convection In Liquid?
The Apparatus Convection In Liquid uses potassium permanganate crystals as its indicator, and the crystals are also listed as a separate product in our range. Tell us in your enquiry whether you need them, so the quotation covers everything for the demonstration.
What heat source should be used with the convection apparatus?
The Apparatus Convection In Liquid needs only gentle heat at one lower corner, so a spirit lamp or a low Bunsen flame is suitable. Warm the glass gradually and never heat the whole base, which would blur the single convection current.
Who manufactures the Apparatus Convection In Liquid?
The Apparatus Convection In Liquid is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges and dealers buy it directly from the manufacturer.
Can the Apparatus Convection In Liquid be ordered for several labs or for export?
Yes, the Apparatus Convection In Liquid can be quoted in multiple units for schools, colleges, dealers and importers in India and international markets. Because it is glassware, mention the destination so suitable protective packing can be included in the quotation.
