Samtech Instruments

• The Heat conductivity apparatus, or Heat Conductivity Apparatus, consists of three metal rods made from copper, brass, and iron, all arranged in a metal ring.
• This setup is mounted on a wooden handle and includes wax and a spirit lamp to facilitate demonstrations.
• The design allows each rod to be heated simultaneously, illustrating that the rate of heat conductivity varies among different materials.
• Additionally, an extra-long copper rod is included to demonstrate that heat takes time to transfer from the hot end to the cold end.

• The Nuclear Fusion Model demonstrates the fusion of atomic nuclei and energy release
• Shows the formation of Mg²⁺ and O²⁻ ions clearly
• Transparent acrylic base with colour-coded atoms
• Ideal for chemistry labs and STEM education

Acid–Base Experiments are practical science activities used to study the nature, properties, and reactions of acids and bases. In these experiments, different substances are tested to determine whether they are acidic, basic, or neutral.

Students commonly use indicators such as litmus paper, pH strips, or natural indicators like red cabbage juice, which change color depending on the acidity or alkalinity of a substance. Acids usually turn blue litmus paper red, while bases turn red litmus paper blue.

Another important acid–base experiment involves mixing an acid with a base, such as vinegar and baking soda. This reaction produces carbon dioxide gas, causing bubbling or fizzing, and demonstrates the process of neutralization, where an acid and a base react to form salt and water.
