  RE-201D,301,501 type rotary evaporator is composed of mechanical part,glass part and lifting constant temperature water bath.Easy installation,the specific procedures are as follows:


  1.Place the host bracket firmly on the workbench.If uneven,four hard rubber feet can be padded.


  2.Move the center of the machine head to a height 48cm from the chassis and tilt it to the right about 25 degrees to tighten the lock nuts on the main engine bracket.


  3.Fix the governor according to the drawing,and plug in the five-core plug of the motor.


  4.Connect the right flange of the condenser to the left interface of the machine head,adjust the movable joints to make the condenser vertical,and fix the condenser with the fixing nut.The condenser circulates the water joint and the vacuum joint backward,and then is fixed with the condenser clip.


  6.Insert the feeding valve into the standard port on the left side of the condenser and connect the PTFE.


  7.Connect the collecting bottle with the ball mouth at the lower end of the condenser and fix it with a stainless steel ball mouth clip.


  8.Adjust the bottle ring,repeatedly adjust the center and upper and lower,and hold the collection bottle steadily.


  9.Put the rotating bottle on the right end of the rotating shaft and tighten the rotating nut.


  10.Place the water bath pot under the rotating bottle and add water to 2/3 of the pot.


  11.Connect the upper joint of the vacuum gauge with a vacuum leather tube at the suction pipe,and connect the lower joint of the vacuum gauge with a vacuum pump or laboratory vacuum switch.


  12.The condenser circulating water joint is connected with cooling water.


  13.Note:RE-501 has the function of releasing material.The discharging valve and flange have been fixed on the collecting bottle.


  Evaporation conditions


  The rotational evaporation rate depends on three conditions:


  1.The higher the vacuum,the faster the evaporation speed.The vacuum degree of water evaporation should not be less than 0.096MPa.


  2,the higher the water temperature,the faster the evaporation speed,but generally do not exceed 80℃,according to the specific process requirements.


  3.The lower the cooling water temperature,the faster the evaporation speed,and the better the effect of refrigeration water.


  Operating procedures


  1.Vacuum pumping:after opening the vacuum pump,it is found that the vacuum can not be hit.It should be checked whether the bottle mouth is well sealed,whether the vacuum pump itself leaks air,whether the sealing ring at the rotating shaft is intact,and a vacuum switch in series in the external vacuum tube can improve the recovery rate and the evaporation speed.


  2,feeding:using the vacuum negative pressure of the system,liquid can be sucked into the rotating bottle with PTFE hose on the feeding port,liquid should not exceed half of the rotating bottle.This instrument can be continuous feeding,feeding needs to pay attention to:①turn off the vacuum pump;Stop heating;(3)After the evaporation stops,slowly open the feeding valve cock to prevent backflow.


  3.Heating:This instrument is equipped with specially designed water bath,which needs to add water first and then power on.The temperature control range is 0-400℃for reference.Due to the existence of thermal inertia,the actual water temperature should be about 2 degrees higher than the set temperature,and the set value can be modified when used.Temperature setting:power on the water bath,SET the required temperature:press SET key,the upper row shows SP.Press the shift key(<;<)Make the number that needs to be modified flash,press the up or down key,make the bottom row display as the desired value.Press SET again to return to standard mode.


  4,rotation:open the speed switch,adjust the rotation to the best speed,pay attention to avoid water vibration wave.


  5.Connect the cooling water.


  6.Recycling solvent:turn off the vacuum pump,open the feeding switch to deflate,and take out the solvent in the bottle.


  Matters needing attention


  1.Vacuum degree is an important process parameter of rotary evaporator,and users often encounter the problem that vacuum degree can not be hit.This is often related to the nature of the use of solvent,biochemical pharmaceutical industry often water,ethanol,propionic alcohol,acetic acid,ethyl ester,ether,petroleum ether,chloroform,methyl benzene and so on as solvent,and the general vacuum can not resist strong organic solvent,can first choose strong corrosion resistance special vacuum pump.


  A simple way to check whether the instrument is leaking air is to clamp off the external vacuum tube and observe whether the vacuum gauge on the instrument can be kept for five minutes.If there is air leakage,check whether the sealing joints and the sealing rings on the rotating shaft are effective(see Maintenance).Check the vacuum pump and vacuum piping if the equipment is working properly.


  2,the instrument motor with E insulation,winding using polyester high-strength enameled wire,the use of the environment altitude is not more than 1000 meters,the ambient temperature is not more than 40℃,continuous use of motor surface temperature rise(motor surface temperature and the environment difference)is not more than 45℃is normal can rest assured to use.If the temperature rise exceeds 45℃,check the relevant transmission lubrication system.If the ambient temperature is very high and the water bath temperature is also very high,the user can use the fan to cool it.


  3,glass should be handled gently,before and after use should be cleaned and dried.


  4.The heating tank should be filled with water first and then electrified.Dry heating without water is strictly prohibited.


  5.Before the installation of the grinding instrument,a small amount of vacuum grease should be evenly applied to increase the air tightness.


  6.After installation,the head should be locked tightly and cannot be moved.


  7,precious solution should be done simulation test,confirm the application of the instrument before the normal use.


  8,accurate water temperature is directly measured with a thermometer.


  9,after the end of the work,turn off the switch,unplug the power plug.


  maintenance


  1,the sealing structure at the left end of the rotating shaft,maintenance once a week,scrub clean and coated with a small amount of vacuum grease(recommended 7501 vacuum grease)


  2.The special sealing ring at the left end is the key part of air tightness.If found in use and solvent insoluble(expansion,fat,etc.)can choose acetone resistance,ethyl acetate or chloroform and other special special sealing ring.
