This apparatus is ideally suited to demonstrating Boyle's Law to groups of students. Colored oil is gradually pumped from a reservoir into a tube containing air. While the volume of air is read from a scale clearly visible behind the tube, pressure is measured by a Bourdon gauge. The glass tube is extra strong and additionally protected by a plastic safety screen. The Bourdon gauge is fitted with a transparent plastic back to allow students to see its working parts. The apparatus is supplied complete with red oil.
