BoyleŸ??s Law Apparatus - Deluxe

Ideally suited apparatus to demonstrating Boyle’s Law. Coloured oil is gradually pumped from a reservoir into a tube containing air. Whilst 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. Bourdon gauge is fitted with a transparent plastic back to allow students to see its working parts. Supplied with oil. This apparatus does not require mercury.
