Comprising five removable glass tubes in a sliding frame and supported in a water trough.
For demonstrating the different thermal expansions of various liquids.
Comprising five glass tubes in a frame and supported in a water trough.
The frame has a special sliding arrangement with clips to hold glass bulbs with tubes.
The bulbs can be easily removed and fixed and have funnel formation on top for easy filling.
To determine the co-efficient of absolute expansion of mercury.
Glass tubes with vertical limbs contained within glass jackets approx.
460 x 25 mm height x diameter are closed by bungs and fitted with inlet and outlet tubes.
Upper ends of these vertical limbs are angled on emergence from the jackets to produce two short, adjacent limbs placed against a silvered glass scale 0 to 12 cm x 1 mm.
Mounted on stand 610 x 230 mm, height x width.
Overall height 750 mm approx.
supplied without mercury.
To illustrate expansion of metal on heating and contraction on cooling, with steel bar of length 100 x 10 mm and plated brass gauge with a cutout to just accommodate the bar and two holes through which the bar passes when cold.
Fitted on a wooden base cast metal uprights and rod mountings.
A 20-0-20 scale is provided to notice the expansion in rods.
The counter weighted needle is used for easy reading.
A knurling screw is provided for zero adjustment.
Supplied with three metal rods one of each Aluminium, Brass and Steel.
Copper calorimeter 75 x 50 mm with felt insulation, outer vessel of 100 x 65 mm size with a plastic lid having holes for thermometer and stirrer.
A thermometer holder is fixed to the outer vessel. Complete with stirrer.
To determine co-efficient of expansion of a gas at constant pressure.
A glass U-tube with a bulb and stopcock at one end, the other limb being open.
An outlet tube from the bottom of the U tube passes through a rubber bung and has a stopcock at the end.
The stem below the bulb is graduated 3 x 0.1 ml. An inlet tube with a mohr clip also passes through the bung.
A glass water jacket encloses the U tube.
All glass parts made of borosilicate glass requires only 20 ml mercury, which is not included.
Jolly's thermometer bulb connected via a 3-way stopcock to mercury tube.
Sliding indicator on right hand limb with reservoir sliding on vertical clamping rod.
Metal vessel to surround the bulb.
Mounted on wooden stand, height 740 mm.
All glass parts except reservoir are made of borosilicate glass.
