Chemistry, a branch of physical science, is the study of the composition, structure, properties and change of matter. Chemistry is chiefly concerned with atoms and their interactions with other atoms - for example, the properties of the chemical bonds formed between atoms to create chemical compounds. As well as this, interactions including atoms and other phenomena - electrons and various forms of energy—are considered, such as photochemical reactions, oxidation-reduction reactions, changes in phases of matter, and separation of mixtures. Finally, properties of matter such as alloys or polymers are considered. Chemistry is sometimes called "the central science" because it bridges other natural sciences like physics, geology and biology with each other. Chemistry is a branch of physical science but distinct from physics. The etymology of the word chemistry has been much disputed.The origin of chemistry can be traced to certain practices, known as alchemy, which had been practiced for several millennia in various parts of the world, particularly the Middle East.

Chemistry Lab Model

Atom Activity Model

Atom Activity Model

Useful for exploring and demonstration of atomic orbital structure to a group of students. This durable, and attractive transparent model of atom has been designed to permit its use on over-head projector. Comprises a clear, thick plastic round disc with small hemisphere at the center representing nucleus and circular orbits clearly marked on the disc to represent orbits. Colorful pieces clearly depict the location of subatomic particles in the atom and their arrangement. This activity reinforces concepts of atomic numbers, atomic numbers, atomic mass, filling order os shells, electro-neutrality and ionic charge.
Crystal Models Set

Crystal Models Set

Model kits for assembling various crystals lattices in skeletal form. The lattices represent certain classic structures and has been built to a large enough size so that their different faces can be seen. Each set contains different colored jacks (red, black and white) and connectors (long and short) in a prescribed number to be joined together to form crystal structures. These Complete with assembly instruction.
Atomic Model Set

Atomic Model Set

Useful for construction of 3-dimensional molecular structures of various organic and inorganic compounds and demonstrating their geometries. The set consists of moulded balls of different colors and sizes along with connecting lugs of different sizes. The balls have holes to facilitate the fixing of lugs. Complete components moulded in polystyrene. The set comes nicely packed in a compartmented plastic box.
Simple Inorganic Molecular Model Kit

Simple Inorganic Molecular Model Kit

The kit makes basic concepts about the principles of molecular geometry easy to visualize and understand. This kit offer building of a large number of 3-dimensional molecular models with a visual appreciation of Molecular Bonding. Also demonstrates, how the shape of molecules are determined by the number of bonds plus the lone pairs in the valence shell of the center atom. Showing lone pairs is a unique speciality with these models. For showing the molecules based on tetrahedron you can make methane, for triangle by pyramid, you can make phosphorus pentachloride; and for octahedron you can build Sulphur hexaflouride and soon. Some of the structures that can be easily built include : CO2, CH4, PCl5, SF6, NH3, BCL3, Sulphur ring SH, oxides of Nitrogen, Phosphorous P4 molecule, H2SO4, simple and complex structures, and many more. Contents : Oxygen, Nitrogen, Sulphur, Phosphorous, Chlorine, Hydrogen, Covalent & Multiple (total components about 140 Nos., packed in a suitable plastic case. Also includes a teachers guide/instruction manual with full details on how to make all these model and more.
Organic Molecular Model Building Kit

Organic Molecular Model Building Kit

Innovatively designed for your convenience. This kit offers you the building of organic molecular models for almost all the important structure covering each and every topic. The main speciality is the design of our atoms with molded prong to provide maneuverability for rotation. You can show the electron clouds. Separate tubes provided for covalent & multiple bonds. Hence, these models are way ahead of the ball & stick type. With this kit, you can built plenty of models. Saturated Hydrocarbons, unsaturated hydrocarbons, functional groups : Alkanes, Alkenes, Alknes, Alkynes, Alcohols, Aldehides & Ketones, Benzene & its Derivatives, etc., and many more. Contents : Carbon, Oxygen, Nitrogen, Chlorine, Sulphur, Phosphorous, Hydrogen-atoms, Covalent bond Hydrogen bonds & multiple Bonds (Total components about 200 Nos., packed in a suitable plastic case. A teacher's guide/instruction manual with full details on how to make is also provided.
