This kit enables to test paper chromatography. All chromatographic techniques consist of a system with a stationary phase and a mobile phase that cannot be mixed […]
CB-IN-23/EV
The test proposed by this kit enables to separate and precipitate the constituents of a homogeneous mixture leading to the formation of crystalline solids. In fact, […]
CB-IN-26/EV
Carrying out this test, students can realize how heating a liquid leads to the phase transition from liquid state to gas; then the vapours provokes the […]
CB-IN-21/EV
The objective of this test consists in separating the constituents of a homogeneous mixture by the physical process of evaporation. Water is removed by evaporation leaving […]
CB-IN-24/EV
This kit enables to separate the iodine contained in a hydroalcoholic solution (tincture of iodine) by extraction. This technique applies the different solubility of iodine in […]
