Activités de thermodynamique
Avantor propose un catalogue complet d’instruments et d’outils utiles pour démontrer les concepts fondamentaux de la physique, applicables à la vie quotidienne aussi bien à l’intérieur qu’à l’extérieur du laboratoire. Démontrez des notions clés telles que l’accélération sur un plan incliné, la friction, l’énergie potentielle et cinétique, la conductivité électrique, les champs magnétiques, les longueurs d’onde et la vitesse du son, entre autres. Les matériaux pédagogiques durables sont conçus pour une utilisation intensive et régulière, et tous les modèles sont faciles à utiliser.

Differential Pressure Bottle
A dramatic visualization of air pressure. This 1000 ml bottle has a balloon attached to its neck and an additional hole in its base fitted with a rubber stopper. You cannot inflate the balloon with the stopper in place, but remove the stopper and the balloon easily inflates. Replace the stopper, fill the bottle with water, remove stopper and Whoosh! – a geyser erupts!

Thermostat
This working model thermostat will demonstrate how differential expansion is used to control temperature. A bimetallic strip is used to open or close an electric circuit when temperature changes. The contacts will carry about three amperes. The unit can be operated with a 6 V lantern battery, low voltage power supply, or a blow dryer. Mounted on a metal base; approximately 15 cm high.
