Rotatory Evaporator

Features of BC-R203 Type Rotary Evaporator
(Patent registered for the key structure)
Bottle Fastener
All seal parts are made of the advanced materials, which can resist the corrosion by almost all the chemicals. Dynamic seals are ultra-wearable.
Cooling tubes are enlarged and a variety of rotary bottles ranging from 0.25L to 5L can be employed with high cost effectiveness.
Combination with #24 standard mouth rotary bottle is available by means of a transition joint.
Quick fastening and removing are realized by means of a bottle fastener. Meanwhile the glass axis can be removed easily.
Simple imported temperature controller is used for temperature control.
Electronic stepless speed adjustment is applied and the alternating motor is employed with long service life and free from any sparkle.
Unique normal close manual controlled lock device is employed and the equipment can move up/down freely. The lock operation is easy and reliable.BC-R203 Type Rotary Evaporator
rotatory-evaporator 50L & 20L Rotary Evaporator
New Key Features:
1.All joints are connected with flanges and composite seal.The main seal material is anti-corrosive and reliable PTFE material.
2.The bottom outlet of the collecting bottle is equipped with PTFE lengthened screwed valve with multiple seals.
3.New enhanced vaulted diverter, safe and reliable,overcomes the disadvantage on the previous trifurcate structure.
4.The inlet of the collecting bottle is equipped with special composite valve that can freely control the gas and liquid flow with excellent circulating and sealing performance.
5.The standard seal pieces are the up-to-date composite seal ring.
6.The rotary sealing uses special ultra-wearable PTFE, corrosion resistant.

Use of Rotary Evaporator
The rotary evaporator can heat at a constant temperature in a minus pressure system. It forms a film through the rotation process and then the condenser reclaims the menstruum. It is especially applicable to the concentration and crystallization of the thermal sensitive materials and the reclaim of the separated menstruum. After improvement, it can also be used for the extraction of reclaimed materials. So the rotary evaporator is an ideal instrument for the research and production in various fields, such as science and education, biology, pharmacy, chemical and food industry etc.

Features of Rotary EvaporatorHigh evaporation rate and reclaim rate, advanced frequency conversion and electronic speed adjusting ensure its electrical performance.
The alternating current inductance motor with a steplessly adjusted speed has a longer service life

without electronic brush and sparkle.
The equipment is series-designed with various modules, resulting in high expansibility and
easy installation, repair and maintenance.
Elaborately designed seal system has a high corrosion resistance with a vacuum degree of lower than
All glass instruments are made of GG-17 high temperature resistant borosilicate glass with excellent
physical and chemical performance.
All parts are anti-corrosive including the stainless steel base, water bath, hull, main rod and aluminum
alloy cast etc.
All key seal parts, frequency transducer and electronic parts are imported from abroad.
