Philip Harris Boyle’s Law Apparatus: Vertical

Designed for demonstration, the column is clearly visible to the whole class without them having to crowd around the demonstration bench. A wide-bore glass tube is mounted vertically in front of a scale graduated 0 to 65cm³. Zero corresponds to the inside of the closed (top) end of the tube.

Air is confined in the tube by coloured water or oil (not included) contained in a metal pressure chamber which is fitted with a Bourdon-type gauge calibrated 0 to 3.4 x 10^5 Pa. As the pressure in the chamber is increased using a pump (not included), coloured water or oil is forced into the glass tube and the volume of the contained air and its actual (total) pressure are clearly indicated.

The tube is of extra strong glass having a very large safety overload margin.

As a further precaution a plastic safety screen is secured over the front.

• Overall height: 690mm

Pump and Adaptor for Boyle’s Law Apparatus is also required for use (B8R08103).
