1. evaporator use with circulating water vacuum pump to offer a
vacuum environment for reduced pressure distillation, they are
widely used for vacuum filtration, vacuum evaporation, vacuum
degassing, etc.
2. evaporator matching use with GDSZ series high and low
temperature circulating pump to quickly cooling or warming, the
circulating pump is an efficient equipment for quick temperature
adjustment.
3. vacuum evaporator price matching use with DLSB series low
temperature cooling liquid circulating pump to conduct chemical
reaction and medicine storage which requires low temperature
environment.
Ask: What's the operating principle of 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 condenser pipe and concentrate to isolate the
material to reach experiment requirements.
Ask: What's the core technology of 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
condenser?
Answer: They have no difference essentially. Vertical condenser is
gradually popular because of its small space usage and convenience
for transportation and use. Most high-capacity instruments use
vertical 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:How about the anti-explosion ability of R series Rotary
Evaporator?
Answer:Our company's Rotary Evaporator adopt alternating current
dynamo, stepless speed regulating (or frequency control), no
electric brush and no spark in operation. Water bath kettle which
goes with the evaporator adopts nitrogen-sealed relay control,
silicon-controlled contactless switch and vacuum switch. Manual
control switch adopt twice circuit control which make electric
current less than 3mA and has favorable anti-explosion
feature.
Ask:How to select all kinds of vacuum evaporator price?
Answer: As for structure, our R series products all have excellent
corrosion resistance ability and leakproofness ability. According
to the solvent volume, 2L, 3L, 5L's machine is fit for lab and
sample test; 5L, 10L, 20L's machine is fit for medium experiment;
20L, 50L's machine is fit for medium experiment and production,
especially suitable for the extraction of metal ion-avoiding
polluted material.
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 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.
