Othmer Still Distillation apparatus vapor liquid equilibrium

    Price: $1,600.00    POD Price: $950.00    

Othmer Still used to determine vapor liquid equilibrium data, Distillation apparatus vapor liquid equilibrium improved. The main body of the still is vacuum jacketed and silvered with expansion bellows in strategic location and houses the entrainment separator with a hood the lower unit of the still is insulated and one leg is wrapped with a nickel heating coil thermocouple wells are placed in the most critical areas for connecting to instrumentation to determine the exact point of equilibrium. Ethanol water is a sample distillation

Kontes-Martin Spinning Band Distillation Still

    Price: $8,000.00    POD Price: $3,000.00    

Kontes-Martin Spinning Band Distillation Still Used to fractiionate charges as small as 10 ml and as large as 70 ml.  A spinning band of Stainless Steel rotates inside of a precision bore column that is vacuum jacketed and silver lined, achieving high fractionaltion efficiency with minimal hold up. Additional heat compenssating jackets are used for adiabatic balancing of the vapor path to avoid hot spots. 7 temperature monitoring thermocouple positions permit precise control of temperature gradients.  A T-Line Laboratory vaviable speed stirrer is used to motor the band.  A Flexopulse timer unit is used to set the reflux ratio. The unit is mounted on a cabinet that incorporates the electrical, water and vacuum systems. 

Technical Data

Size of charge 2 to 70 ml, Pressure Range Atmospheric to less than 1 mm hg absolute, Holdup Using di-butyl phthalate holdup was found to be between 0.5 and 0.7 ml. at normal biolup rates and at 1 mm hg absolute head pressure.  Biolup rate Varies from 20 to 100 ml/hr, Take off Rate Rate is held below 2 ml/hr for efficient fractionation. Efficiency Theorectical plates values range from 20 to 150 depending on biolup rates , motor speed band material and sample characteristics. Pressure drop at  a 40 ml/hr boilup rate of di-butly phthalate at 1mm hg at the head the pressure drop throught the column is 1.5 mm hg,
