Dean and Stark Apparatus

It may be defined as the apparatus consist of 500 ml heat resistant glass with neck having ground glass joint, a condenser made of heat resistant glass receiver – also made of heat resistant glass with ground glass joint leading to the flask and graduated tube. Capacity of receiver will be 2 or 10 ml. (please specify while ordering – or else 2 ml receiver shall be supplied).

Features:-

• Highly durable
• High strength
• Affordable
• Desiccant
• Condenser
• Graduated collection tube
• Core sample
• Flask
• Solvent
• Two types of Dean-Stark traps exist – one for use with solvents with density  less  than  that of
       water and another for use with solvents with a density greater than that of water.
• The  Dean-Stark  apparatus  typically  consists  of  vertical  cylindrical  glass  tube,  often  with a 
       volumetric  graduation  along  its  full  length  and  a precision stopcock at its lower end, very 
       much like a burette.
• The lower end of a reflux condenser fits into the top of the cylinder.
• Immediately below the joint between the condenser and the cylinder is a sloping side-arm that 
       joins the cylinder to a reaction flask.
• The lower end the side-arm turns sharply downward, so that the side-arm is connected to the 
       reaction flask by a vertical tube.
• The reaction flask is heated. Boiling chips within it assist with the calm formation of bubbles of
       vapor containing the reaction solvent and the component to be removed.
