Plant quality testing kit: nutrient components
A set for educational analysis of the nutritional components of plant materials: sugars, starch, vitamins, pigments and other indicators.
The kit supports educational analysis of plant materials, including sugars, starch, vitamins, pigments and other indicators. Students learn the principles of quantitative biochemical analysis, work with a spectrophotometer and calibration curves, and practise titrimetric determination of vitamin C and extraction of bioactive substances from plants.
