Rotary Evaporator
Rotary evaporator under reduced pressure, mainly used for continuous distillation large amounts of volatile solvent. Especially for receiving liquid extract concentration and separation by distillation, separation and purification of the reaction product can be. The basic principle of rotary evaporator is vacuum distillation, is also in the vacuum case, when the solvent distillation, distillation flask in continuous rotation.
Structure:
The distillation flask but with a standard ground interface pear shaped or round bottom flask, a high reflux condensation tube is connected with the vacuum pump snake through another opening, reflux condenser with a receiving flask grinding mouth connected, for receiving by organic solvent evaporation. In between the condensation tube and the vacuum pump with one three pistons, when the system is communicated with the atmosphere, the distillation flask, solvent transfer liquid receiving flask, removed, when the system and vacuum pump is communicated, the system should be in a vacuum state. When in use, should first decompression, start the motor to rotate the distillation flask, the end, should first stop, and then through the atmosphere, to prevent the distillation flask shedding in rotation. As the distillation of heat, often with a constant temperature water tank corresponding.
Working principle:
By electronic control, the flask in the most suitable speed, constant speed rotation to increase the evaporation area. Through the vacuum pump and the evaporation flask in a negative pressure state. The constant temperature heating evaporation flask are placed in the rotation at the same time in the water bath, bottle solution under vacuum flask in rotation within the heating diffusion evaporation. Rotary evaporator system can be sealed vacuum to 400 ~ 600 mm Hg; heating bath heating distillation flask boiling point solvent, heating temperature can be close to the solvent; also can be rotated, speed is 50 ~ 160 rpm, the solvent to form a thin film, increase the evaporation area. In addition, in high efficiency cooler effect, the hot steam rapid liquefaction, accelerate the rate of evaporation.
Characteristic:
Rotary evaporator. All IKA aika has a built-in motor, the device can automatically under the power of the flask to heating pot above position.
In the liquid sample and evaporation bottle centripetal force and friction force, the liquid sample bottle in the evaporation surface to form a layer of liquid film, large heating area;
Boiling the samples generated by the rotation of the force effectively inhibit samples. The characteristics and its characteristics of convenience, rotary evaporator to modernization can be used for fast, gently on the vast majority of samples were distilled, even if there is no experience in the operation of the operator can complete. Recommend the use of Taikang biotechnology products.
Methods:
The height adjustment: manual lifting, rotating machine handwheel clockwise column above, rise, decline reversed to. Electric lift, touching the rising key host up, hand touch down key host decreased.
The condenser is provided with two outer connector is connected with the cooling water, a head connected with a water inlet, the other end is connected with the tap water outlet, in general, the better the condensate water temperature is lower. Port is connected with the vacuum pump vacuum joints, skin tube for vacuum pumping.
The boot before the first speed control knob l to a minimum, press the power switch indicator light, and then slowly to the right hand to the desired speed, generally large evaporation bottle, low speed, solution viscosity with low speed. The flask is the standard interface of No. 24, random with 500ml, 1000ml two flasks, amount of the solution generally not more than 50% is appropriate.
The use, should first decompression, start the motor to rotate the distillation flask, at the end, because the first stop motor, then through the atmosphere, to prevent the distillation flask shedding in rotation.
