Molecular model construction kit, basic set

 Product No: 39820-88

Function and Application

With these big elements (Atoms) for molecular models structures of chemical compounds can be presented especially vividly also to a greater number of observers

Benefits

  • structural elements of shockproof plastic
  • diameter of the elements: 38 mm(ostentatious)
  • chemical elements characterized by internationally usual colors
  • angularity of the connections by precisely rivetted push-buttons according to the valences of the elements
  • transparent connectors:straight for single bond and scurved for double and triple bonds
  • push-buttons for a secure connection of the elements even after years of use
