The working principle of glass reaction kettle

The working principle of a,glass reaction kettle Glass reaction kettle is a small sample in the

modern chemical experiments,biological pharmacy and the synthesis of new materials ideal

equipment,the use of the more extensive in the laboratory.What is the general working principle of

glass reaction kettle? Glass reaction kettle in setting under the condition of constant temperature,in an airtight container,in mixing,reaction under atmospheric pressure or negative pressure,and can control the reaction solution evaporation and reflux.Generally speaking,there are

single glass reaction kettle and double glass reaction kettle.Second,the USES and working principle of single-layer glass reaction kettle Single-layer glass reaction kettle can provide high temperature reaction (the highest temperature can reach 300 ℃);Can also be a vacuum,thus negative pressure reaction.Single-layer glass reaction kettle can undertake various solvent synthesis reaction under the condition of constant temperature,the instrument response part for manipulation of the sealed structure,with continuous negative pressure suction available all kinds of liquid and gas,also can do reflux or distilled at different temperatures.

Single-layer glass reaction kettle working principle is: through a silver film directly heated by heating tablets in reaction kettle body,make the material constant temperature heating inside the reaction kettle,and can provide a stir.www.dongfeng-motor.com Material in reaction

kettle to reaction,and can control the reaction solution evaporation and backflow.Reaction

finished,single-layer glass reaction kettle pot cover and the motor parts mechanical lifting

(optional electric hoist),pot body can rotate 360 degrees,for dumping material discharging,convenient in operation.Is a modern chemical samples,pilot tests,biological pharmacy and the synthesis of new materials ideal equipment.Three,use and working principle of double deck glass reaction kettle Double deck glass reaction kettle interlayer can provide high temperature reaction (the highest temperature can reach 300 ℃),can also do low temperature reaction (the lowest temperature can reach 80 ℃).Double deck glass reaction kettle can vacuum,pressure reaction.Double deck glass reaction kettle can be stirring reaction at room temperature,high temperature reaction,negative pressure vacuum distillation reaction,separation,extraction,distillation reflux reaction,reaction.

Glass double reactor designs for the double deck glass,its working principle is: in the lining of the glassware in the solvent can be stirring reaction,mezzanine can connect in different cooling and heat sources (coolant,hot water or hot oil) for circulation of heating or cooling.Through double reaction kettle

interlining,injected into the constant temperature (high or low temperatures) hot-melt media or

cooling media,within the reaction kettle on material in constant temperature heating or cooling.At the same time can be used according to the requirements under the condition of atmospheric pressure or negative pressure of mixing reaction.Material in reaction kettle to reaction,and can control the evaporation and the backflow of reaction solution,reaction finished,the material can be released from the discharging mouth of the kettle bottom,convenient in operation. Rotary evaporator using method

and the matters needing attention Rotary evaporator,we mainly used in need under the condition of reduced pressure distillation of volatile solvent.Especially for the concentration of the extract liquid chromatographic separation and receiving of distillation,separation and purification reaction products.The working principle of rotary evaporator mechanism in a vacuum distillation,in other words,under the condition of reduced pressure,when the solvent distillation,distillation flask in rotation.

The physical structure of the rotary evaporator,the distillation flask inside but with a standard interface pear-shaped or grinding mouth round bottom flask,through such a high return serpentine condenser pipe connected to the vacuum pump,another open reflux condenser pipe connected to the receiving flask with grinding mouth,used to receive organic solvent by evaporation.Between the condensing pipe and vacuum pump have a three-way piston,when system and atmosphere are 6v electric motor interlinked,can the distillation flask,liquid after take out the flask and transfer solvent,when system with vacuum

pump,the system should be in a state of stress.When using,should be reduced pressure,and then start the motor rotating distillation flask,end,should first stop,again through the atmosphere,in case the distillation flask on the rotation.As heat source of distillation,often with a corresponding waterbath. Method of use: 1.The boot before l will speed control knob to a minimum,press the power switch indicator,and then slowly to the right hand to the required speed,low speed,in a general large

evaporation bottle with the viscosity of the solution with a lower speed.24 flask is a standard

interface,random add 500 ml,1000 ml two ac alternators 220v flask,appropriate solution is generally not more than 50%.2.On the condenser cooling water use,two external connector is a head of water,water on the other side,generally by tap water,condensed water temperature,the lower the better the results.Port on the vacuum joint,connect the vacuum pump hose vacuum.3.The height adjustment: manual lifting,on the column above the handwheel,suitable to rise,reverse for fall.Electric hoist,hand touch up key host

up,touching the descent key host.
