Linear Expansion Apparatus Gunther

Edutek Iab Science are Manufacturer Exporter & Supplier of Expansion Apparatus for Physics Lab. Expansion Apparatus offered by us are widely used for experiments, research and studies at various institutions,

Comprising two cast metal end pieces joined together by three nickel plated rods and carrying two sliding V-supports for a glass jacket with inlet and outlet tubes. One end piece fitted with spherometer reading 0.01mm, and other with contact screw. The glass jacket encloses both a brass and a copper rod each of about 50cm length, fitted through corks, a half turn of the jacket changing rod in contact with the spherometer. A thermometer can be attached to either of the rods by rubber bands. A binding post is fitted to each end piece for connecting an electric bell or galvanometer to indicate make/break of contacts.

The students can accurately and easily investigate the expansion of metals with increasing temperature. This is an ideal apparatus for determining the coefficient of linear expansion of a solid. The apparatus comprises of a double metal plastic jacket containing the rods which will be raised to a temperature.
