Cork Glass Bells
Cork Glass Bells (Product Code: SCI-541/066) is a clear glass bell with a corrugated cap, used to enclose plants, specimens and small apparatus in biology, chemistry and physics demonstrations. It measures 150 mm in diameter and 200 mm in length, a compact size that fits on a bench or plate while leaving the contents fully visible. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its plant biology lab equipment.

What Is a Glass Bell Jar Used For?
A glass bell creates a small closed space on the bench. In plant physiology it covers a potted plant or leafy shoot to show water vapour condensing during transpiration, or to keep the air around a plant separate for photosynthesis and respiration comparisons. In chemistry and general science it is used for the classic candle-under-a-jar demonstration and to keep dust or draughts away from specimens, crystals and delicate apparatus.
Stand the bell on a smooth glass plate or tray, and seal the rim with a little petroleum jelly when an airtight enclosure is needed. Lift it with both hands, set it down gently on a flat surface, and clean it with warm soapy water rather than abrasive powders so it stays clear.
