Orsat Gas Analysis Apparatus 3 TEST

Orsat Gas Analysis Apparatus 3 TEST Comprising of Levelling bottle, gas burette with outer jacket, three absorption pipettes, 3-test manifold, calcium chloride tube and rubber below, in wooden-case with sliding doors Construction: An Orsat’s apparatus consists of the following: (i) 100 Ml. Gas Burette With Jacket (ii) 4-Test Manifold (Orsat Bridge) (iii)Levelling Bottle 250 Ml. (iv)Calcium Chloride Tube And Rubber Bellow /Suction Pump (v) Four Absorption Pipettes 1, 2, 3, 4. (P1, P2, P3, P4) The pipettes are interconnected by means of a manifold fitted with cocks C1, C2, C3 and C4 and contain different chemicals to absorb carbon dioxide (CO2), carbon monoxide (CO) and oxygen (O2). Each pipette is also fitted with a number of small glass tubes which provide a greater amount of surface. These tubes are wetted by the absorbing agents and are exposed to the gas under analysis. The measuring burette is surrounded by a water jacket to prevent, changes in temperature and density of the gas. The pipettes1, 2, 3, 4 contain the following chemicals: Pipette 1: Contains ‘KOH’ (caustic soda) to absorb CO (carbon dioxide) Pipette 2: Contains an alkaline solution of ‘pyrogallic acid’ to absorb O2 (oxygen) Pipette 3, 4: Contain an acid solution of ‘cuprous chloride’ to absorb CO (carbon monoxide)
