We always recommend that our teaching customers choose from one of our sets, which are carefully designed to provide all the necessary components for a variety of experiments at every level. However, we realize that experienced customers may have a need for different combinations of our equipment. ###>Nous recommandons en principe d’acheter nos kits qui comprennent tous les composants nécessaires pour les essais correspondants. Cependant, nous donnons au client la possibilité de compléter nos kits avec des composants supplémentaires.
