Both the tubes are mounted on brackets which can be locked on any portion on the metal supporting rods. Stand is made of approx. 1.06 m in height & carries a graduated scale 0 to 100 cm with mm divisions in centre & figured every 2 cm up either side on heavy metal box. Mercury required for this apparatus is approx. 30 cm.
 
Jolly Air Bulb  [106.10 PH]
 
In the apparatus described in 106.9, a Jolly Air Thermometer bulb of 50 mm diameter is mounted on a wooden frame that can be fixed at three places - up, middle , & down on the stand & enable the apparatus to be used as Jolly's Apparatus.
 
Boyle's Law Apparatus  [106.11 PH]
 

A wide bore glass tube is mounted vertically in front of a scale graduated 0 to 60 cm. Zero corresponds to the inside of the closed top end of the tube. Air is confined in the tube by a coloured oil contained in metal pressure chamber which is fitted with a Bourdon type gauge calibrated 0 to 50 lb./in & 3.5 Kg/cm actual pressure. A valve is fitted to the air inlet tube from the pump. As the pressure in the oil chamber is increased, oil in its actual total pressure is indicated directly. The tube is of extra strong glass & plastic safety screen is secured on front.

The overall height of the apparatus : 690 mm approx.
