This new improved Boyle's Law apparatus is ideally suited to demonstrate Boyle’s Law. Coloured oil is gradually pumped from a reservoir into a tube containing air. Whilst the volume of air is read from the graduated tube, pressure is measured by a Bourdon gauge. The glass tube is calibrated and has graduations from 0 - 55cm. The 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 and hand pump.
