Melting Point Apparatus
Melting Point Apparatus
This product is used to determine the melting points up to 450°C. We can measure 3 samples simultaneously. The temperature is regulated by the knob fitted on front panel. A white LED is given inside the unit for clearest view of the melting process. A lens window is also provided at front panel for the best view of melting process. We Can Also Change the Background behind the capillary tubes with the help of a knob given at the back side.

Mega Molecules – The Structure of Water
The kit allows students to explore the attractions between water molecules which are responsible for creating surface tension. Electrical forces between the water molecules are simulated with the help of magnets. The hydrogen atom of one water molecule is attracted to the lone pair of electrons of the other water molecule.
Kit consists of:
2 Magnetic Water Molecules
