Boyle's Law Apparatus

This new improved Boyle's Law apparatus  is  i deally suited to demonstrate Boyle's Law. Colored  Water or 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 to 55 cm. 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. The apparatus has nozzle for tube to use the hand pump and comes with a needle valve to control and release pressure. Supplied without oil and hand pump. This apparatus can be used with Water instead of Oil.
