rotary evaporator is a newly designed rotary evaporator of our company,
this series has 5L, 6L, 10L, 20L, 50L for selection.
rotary evaporator adopts stepless speed function to make rotary flask
rotates in constant speed, the material formed a large area of thin
film, then the constant temperature water bath
begin to uniform heat the
rotary flask and the material is evaporated in high speed under vacuum
condition, the solvent steam is refrigerated by efficient glass
condenser and received to receiving flask.
R-1050A rotary evaporator has following features:
- Equip PTFE valve between condenser and receiving flask, easy operation and good sealing.
valve control, continuous charging, available for vacuum switch in
working condition. The check valve also could be replaced with
hand-operated valve to convenient for operation, better sealing
- The discharging valve is made from teflon, consider of thermal expansion, other valves use glass valve element.
- The water bath is electric lifting, lifting part use deceleration reinforcement motor, lifting process is more stable.
- Use thicken rotary bottleneck to enhance loading bearing strength.
- Use thicken rotary axis to enhance evaporation efficiency.
- If the rotary evaporator sudden power lost during operation, when reconnect the power, it will automatic stop heating.

use with circulating water vacuum pump
, rotary evaporator offers a
vacuum environment for reduced pressure distillation, which are widely
used for vacuum filtration, vacuum evaporation, vacuum degassing, etc..
use with GDSZ series high and low temperature circulating pump (an
efficient temperature adjustment equipment), rotary evaporator can cool
down or warm up rapidly.
- Matching use with DLSB series low
temperature cooling liquid circulating pump, rotary evaporator conducts
chemical reaction and medicine storage requiring low temperature
evaporator flask is mainly used for the concentration, crystallization,
drying, separation and solvent recovery in medicine, chemical
engineering and biopharmacy industry. Under vacuum condition, thermostat
heating and make rotate bottle rotate in constant speed, material
formed a large area thin film in bottle wall and evaporate efficiently.
Solvent steam cooling by efficient glass evaporator condenser and collect to bottle, greatly enhanced the evaporation efficiency.
Especially suitable for the concentration and purification of easily
decomposed biological products. RE-501 is an essential basic instrument
for analysis experiment in higher education units, beneficial for its
small volume, simple structure and cheap price.

- Ask: What’s the operating principle of rotary evaporator?
Answer: Under the condition of negative pressure, evaporating flask
rotating in the thermostat water bath, which makes solution form a thin
film in bottle wall, so as to increase the evaporation area. Evaporating
efficiently under low temperature, then condensate recycling through
evaporator condenser pipe and concentrate to isolate the material to
reach experiment requirements.
- Ask: What’s the core technology of Rotary Evaporator?
Answer: The key is system’s gas tightness, that is whether system can
keep high vacuum degree under all sorts of solvent’s corrosion and
movement state. Henan Lanphan’ s R series instrument, which is sealed by
composite material four fluorine rubber and glass, can stand all sorts
of solvent, has reliable gas tightness and can maintain a high vacuum
degree above -0.096MPa.
- Ask: What factor decides the working efficiency of Rotary Evaporator?
Answer: For same type equipment, mainly includes: steam temperature,
vacuum degree and cooling water temperature. Restricted by some
material’s thermolability, the steam temperature may have certain
limitation when working, so high vacuum degree and low cooling water
temperature are two main factors for efficiency improving (can select
cryopump to lower the temperature)
- Ask: What’s the difference between vertical and inclined evaporator condenser?
Answer: They have no difference essentially. Vertical evaporator
condenser is gradually popular because of its small space usage and
convenience for transportation and use. Most high-capacity instruments
use vertical evaporator condenser.
- Ask: What’s the design basis of main engine and water bath kettle rising and falling?
Answer: It’s mainly from the consideration of convenience, safe and
economical. Generally, small-size rotary evaporators below 5L use main
engine rising and falling and evaporators which are above 5L use water
bath kettle rising and falling.
- Ask: What’s the feature of rotary evaporator comparing to other evaporators?
Answer:It has the advantage of small structure, efficient, easy to
observe and no metal ion pollution. It is applicable for laboratory,
production and valuable material extraction. Its leakproofness ability
can compare favorably with foreign equipment while it remain improvement
in appearance and humanization design.
- Ask: How to select vacuum pump for rotary evaporator?
Answer:We recommend water-circulating pump which can bear all sorts of
solvent corrosion and can vacuumize to -0.095MPa(to satisfy using
requirements). According to the solvent volume, we can offer various
vacuum pump types.
evaporator flask is equipped thermostat water bath kettle can manual up
and down, keep glass part fixed and cut down damage; when evaporating
in low boiling point, collecting bottle also can immerse in ice bath so
as to reduce twice evaporation.
- Beauty in appearance, clear number of vacuum meter.
- Collecting bottle use ground connection, which has excellent performance and is easy to dismount.
- Sealing system is anti-corrosion under high temperature, long service life.
- Among standard bottle neck glass there has PTFE clamp cover, which can prevent glass ground seizure.
type evaporator condenser has strong maneuverability, three choices are
available, can equip cold trap and do low boiling point evaporation.
- 0-120 rotate/speed governing, digital display of rotate speed.
- Its rotate bottle use ISO29 standard bottle neck, which can easily take off by thread and weaken glass damage.
bath kettle’s temperature control range is between 0-399℃, can be used
as water bath kettle and oil bath
kettle, temperature fluctuation is
only ±0.1℃, more stable evaporation, no spark control, much safer.
