1. INTRODUCTION
1.1 Apparatus use and specifications
The RVO 004 Standard and RVO 004 Control rotary vacuum evaporator is used for
evaporation under low pressure at a preset temperature of the heating bath (if the bath is a
part of the delivery) and under permanent and in advance specified stirring of the evaporated
solution. The exhausted vapours condense in a vertical cooler and are collected in a flask.
This ensures that the evaporated solution cannot be damaged and therefore impaired.
RVO 004 Standard is equiped by water bath with the thermostatic temperature
control.
RVO 004 Control is equiped by water bath with the electronic temperature control.

3. STARTING OF OPERATION
3.1 Unpacking of the apparatus
Remove the instrument from the transport packing, check the instrument surface and all
the items according to the delivery note. Please contact the manufacturer or your dealer in case of
instrument damage or a missing part.
Notification: Coat the glass joints with silicone vaseline prior to assembly.
3.2 Apparatus assembly
1.
Screw the bar of the cooler's holder into the nut in the head with the rotating housing,
insert the housing with the openings and grooved nuts and the cooler's holder itself.
2. Insert the pipe into the head with the rotating housing from the side of the heating
bath until the pipe joint snaps behind the ring in the rotating housing. Insert the
arresting rod into the opening in the rotating housing and tighten the nut of the
housing.
3. There is a fixed housing with a nut on the opposite side of the head with the rotating
housing. Unscrew nut (2), insert on the recessed part of the ball adapter (1) and insert
securing ring (3) until it snaps behind the recessed part of the ball adapter. Check
if Gufero packing (4) coated with silicone vaseline is placed by the open side outside
the recess. Check if flat packing (5) is inserted in the housing and carefully insert
the ball adapter with Gufer and the nut on glass pipe (7). Insert the ball adapter
until the end stop and tighten it carefully with nut (2). The half-ball joint of the ball
adapter points downward.
4. Coat all the joints on the other glass parts finely with silicone vaseline.
5. Insert the cooler into the joint in the top part of the ball adapter and also into the
cooler's holder. The top cooler's outlet serves for connecting the subpressure source,
other outlets are for cooling water.
6. Attach the flask with the ball joint to the ball joint using the fixed clamp and tighten
it.
7. Insert the round-bottomed flask on the pipe and secure with the flexible clamp.
8. Insert the inlet pipe with the cock (cock is closed) into the ball adapter.
9. Connect the bushing.
10. Pour water into the heating bath; adjust the end stop of the stand for the roundbottomed flask being immersed in the liquid. The maximum amount of the liquid is
approximately 20 mm below the edge of the heating bath.
Notification: A glass part with a visible crack or another defect must not be used!

3.3 Apparatus control
The instrument is put into operation by connecting the network switch. The round-bottomed
flask starts rotation after turning on the switch. The speed of rotation is controlled by the rotary
knob.
The height of immersion into the heating bath is arrested with a bolt on the telescopic stand.
The bath temperature setting at version Standard is by using the thermostat scroll and at version
Kontrol by degrese scale.
4. MAINTENANCE
4.1 Apparatus maintenance
Do not leave the evaporator surface contaminated from corrosive substances. It could damage the
evaporator coating. Clean the contamined surface with a clean soft cloth. The cloth may be moistened
but not wet. It is also possible to use ordinary washing means for cleaning purposes. It is forbidden to
clean the heating bath with the means which could spoil its smooth surface. In case of sediments of
furning,impurities, particulates of water rusts ,use the cleaning compounds for cleaning of furning or
mellow solution of HCL. In process of cleaning use the protective means recommended by producer of
INGOS Ltd. Laboratory Instruments division
Page 9
applied cleaning compounds.
Caution: Disconnect the apparatus from the network while cleaning it with a wet cloth!
4.2 Sealing replacement
Disassemble the condenser, remove the releasing pipe with the valve, remove the ball-andsocket ground joint flask, release the nut of the ball adapter and carefully remove the actual adapter.
Release the gufero sealing, clean the ball adapter, slightly apply silicone Vaseline onto the new sealing
and mount it into the ball adapter. The sealing cavity faces out of the ball adapter. If necessary, replace
also the flat sealing between the ball adapter and the head fitted with a rotary casing. Perform the
assembly according to the point 3.2. Apply a light layer of silicone Vaseline to the gufero sealing
approximately after 80 operation hours (more often if necessary).
5. DEFECTS AND TROUBLESHOOTING
5.1 Leakage
The main cause of leakage is usually an incorrect sealing assembly. At first you should check that
all joints have been installed correctly. If it is the case, disassemble the glass and verify the condition of
the ball adapter sealing and flat sealing, if necessary replace them. Carefully assemble according to the
instructions, switch the rotation ON and start the vacuum pressure up.
5.2 Other failures
The instrument does not react after being turned on. Check the fuse or replace for a new one
of the same parameters, as appropriate. Check that the rotation is not hindered (turning by hand),
turn on and off the network switch.
The window of the rotation key is flashing, rotating parts are not moving. Ensure that Rotation
blocking knob is set to ”Unlock” and than press rotation key again. The window of the rotation key is
flashing. Check that there is not anything which could impede the flask from its rotation (manually),
switch the mains switch OFF and ON again.
The bath no warms.Put out the socket plug of the bath and let the bath cool down. Plug in again fill
up the water or oil and set required temperature.
6. SAFETY AND OPERATION CONDITIONS
6.1 Operation safety
Securing the rotation of the evaporated sample: Overcurrent protection of the
driving motor. If the resistance against rotation exceeds a specified limit, the power
supply of the driving motor is disconnected. Securing the bath heating: With thermal
fuse during overheating above 200°C.
INGOS Ltd. Laboratory Instruments division
Page 10
6.2 Operation conditions
The instrument is designed for work under standard laboratory conditions at
temperatures from 10 to 30°C and air humidity to 80°C.It is forbidden to handle a
bath heated to a temperature higher than 40°C.
Attention! Be especially careful when replacing a round-bottomed flask after
increasing the concentration of the evaporated sample. If the flask cannot be removed
easily from the cone, carry out further operation only after cooling the bath.
Caution! If you are replacing the round-bottom flask after the vaporized solution has become
thicker, pay particular attention and if it is not possible to remove the flask easily from the cone, carry
out any other handling only after the cooling of the bath.
Caution! If you use oil as the filling of the heating bath, the heating bath must be properly dried
before its being filled.
