Heating Mantles
Heating mantles are used to uniformly heat various glassware vessels such as flasks, by placing them directly on the heating element without substantially increasing the risk of glass shattering. These heating mantles are made of rolled aluminium body. The heating element is flexible, insulated and anchored securely in glass fabric. The temperature can go upto 350°C, controlled through energy regulator.
Please note that the heating element cording may be slightly brown in color. This is a result of heating during the quality control process.

Helmholtz Coil
Helmholtz Coils are a special arrangement of coils that are placed in such a way as to generate a very uniform magnetic field between them when a current is applied. The strength of the magnetic field is proportional to the number of turns in the coils and the current applied to them. The Supertek Helmholtz Coils setup consists of two field coils mounted on a track to provide a uniform magnetic field between the coils. The proper separation for Helmholtz coils is marked on the track. A pair of precision coils and 400 turns of wire are wound on heat resistant former of about 150 mm diameter.

Hero's Engine
Hero's Engine demonstrates the principle of jet propulsion. The apparatus consists of a small Erlenmeyer flask with a rubber stopper and two tubes with tangentially oriented jets. A collar is provided around the flask to hang it above a heating source. When water boils inside the flask, steam escapes the jets and the flask spins.

Hydraulic Jack Model
The set includes a basic jack stand with plunger and a main cylinder, four smaller cylinders, a set of connecting hoses and valves. Smaller cylinders can be easily connected to a basic jack stand with a large main cylinder. Students can lift a heavy object, such as a stack of books, by applying a small amount of force to one of the four smaller cylinders. Students can adjust the mechanical advantage by using different input cylinders. Device may also be used to demonstrate Boyle's Law using air or other gases. With Instructions
