Molecular model construction set, basic, demo, ball sizes 30/40/50 mm

Amply equipped molecule construction kit with large balls of 30 (hydrogen), 40 (e.g. carbon) and 50 mm diameter (chlorine and sulfur), ideal for front-of-class teaching, for building open-chain (acyclic) and ring-shaped (cyclic) organic standard molecules in the form of open sphere-rod models or as room-filling dome models, as they are topics in school and in the early semesters of university education; e.g.: alkanes, alkenes, alkynes, alcohols, amines, haloalkanes, mercaptans, and many more. Also suitable for the study of different conformations and stereoisomers. Large sphere diameters Equipped with all necessary elements and connectors Optimally suited for both beginning and advanced chemistry classes in high school Supplied in a transparent plastic box, which allows for clear and convenient storage All parts are extremely stable and colored in the international standard color Diameters: for hydrogen: approx. 30 mm for carbon, oxygen, nitrogen, halogen and metal: approx. 40 mm for chlorine and sulfur: approx. 50 mm Contents: 24 spheres of hydrogen (1 connecting hole) 2 spheres of carbon (2 connecting holes) 8 balls of carbon (3) 12 balls of carbon (4) 2 balls of oxygen (1) 4 balls of oxygen (2) 2 balls of nitrogen (3) 2 balls of nitrogen (4) 4 balls of halogen (1) 2 balls of metal (1) 2 balls sulfur (2) 2 balls chlorine (1) 40 connectors, short (15 mm) 40 connectors, medium (46 mm) 24 connectors, long (70 mm)
