1. Low Pressure Shaker Type ( In glass) : A compact unit for chemical reactions which require the agitation of solution in the presence of a gas under pressure up to 60 lbs per square inch. It is recommended for the numerous reduction and condensations which arise in the synthesis and investigation of organic compounds which are accomplished conveniently by treatment with hydrogen in the presence of a suitable catalyst.
2. Low Pressure Shaker Type ( In Stainless Steel) : This unit is similar to the glass model but the reaction bottle is of stainless steel in two litre capacity and the whole unit is proportionately modified. It can also accommodate stainless steel reaction bottle of 1 liter capacity.
Description: The apparatus consists of a shaker mechanism with 1/4 H.P. AC electric motor (totally enclosed fan cooled type), glass reaction bottle capacity 500 ml, bottle clamp, perforated steel guard, gas supply tank of nickle plated brass capacity 4 litres and pressure gauge range 0 to 100 lbs per square inch. The reaction bottle of borosilicate glass and supply tank are individually tested to 100-125 lbs per square inch pressure. It can also accommodate glass reaction bottle of 250 ml capacity. Complete with tank inlet valve assembly, three way valve assembly for use between tank and reaction bottle, 6" pressure tubing for connecting gas supply tank to hydrogen cylinder, 15" of pressure tubing for connecting reaction bottle to gas supply tank, tubing clamps, cord and plug. All parts of apparatus are powder coated.
The compound gauge (pressure-cum-vacuum gauge) fitted over 3-way valve assembly connecting tank to reaction bottle indicated vacuum in the initial evacuation bottle before reaction and pressure at the time of reaction. The pressure measured by means of the gauge attached is a quick and accurate method of measuring the rate of reaction and also the extent to which the reaction in the bottle has proceeded.
The apparatus is fitted on a heavy M.S. base plate, powder coated with metalic blue finish and other parts are chrome plated.
