IKA VACSTAR digital 0020016236 — диаграммные вакуумные насосы: использование и безопасность [22/144]

IKA VACSTAR digital 0020016236 [22/144] Caution
22
Use
WARNING
The device must not be used for:
- evacuating biological habitats,
-
evacuating explosive, corrosive
or similar gases,
- throughput/use of liquids
The device is not suitable for:
- pumping up objects
- pumping liquids
- use in potentially explosive
atmospheres
- underwater
- underground
The laboratory diaphragm vacuum pump
IKA Vacstar digital is
used
together with other laboratory devices to create a vacuum.
For specific vacuum control, an additional vacuum controller IKA
VC 10 or IKA rotary evaporator RV 10 auto is required.
Correct use
Useful information
DANGER
You can
prevent
the
release of
solvent vapours
into
the
atmosphere
using
a downstream
emission
condenser.
CAUTION
Special care must be taken when
working
with gas mixtures that
include condensable gases (e.g.
solvents). If diaphragm pumps are
used
with
such
gases
they
condense
in the pump’s air flow. This leads
to a build-up of pressure in the
vacuum
chamber
,
which
in
turn
influences the effectiveness and
service life of the diaphragms and
valves.
If liquid or condensate enters the
vacuum chambers, the specified
minimum working pressure is no
longer achieved.
To
protect
the inner valves and
diaphragms against liquid, use an
upstream condensate separator,
such as a Woulff bottle.
CAUTION
It is generally recommended that
you run the pump with no load at
the end of the
process
(no-load
operation, approx. 3 up to max. 5
minutes) to dispel any residues in
the pump.
If applicable, vent the recipient.
To do this, remove the suction line
during manual operation.
NOTE
Observe the operating instructions
of the relevant devices.
Diaphragm vacuum pumps are oscillating displacement pumps.
The diaphragms expand the volume of the vacuum chamber to
produce an underpressure, which sucks air into the chamber. The
air is then pressed out of the vacuum chamber by subsequent
compression. Changes between the inlet and outlet are controlled
by diaphragm valves.
The physical unit for pressure is 1 Pascal [Pa].
However people often still use the unit millibar [mbar] colloquially.
1 mbar = 100 Pa
1 bar = 10
5
Pa
1 Pa = 10
-5
bar
1 Pa = 0.01 mbar
Area of use (only indoors)
The device is suitable for use in
residential
areas and all other
areas.
The safety of the user cannot be ensured:
if the device is used in conjunctions with accessories not
made or recommended by the manufacturer!
Standalone operation
The vacuum pump can be operated without a controller.
The delivery
capacity
can be set using the
adjustable
speed.
Generally speaking, the smaller the volume to be evacuated, the
lower the speed should be. The final pressure is not controlled.
Operation with accessories
Along with the accessories recommended by IKA, the vacuum
pump
IKA Vacstar digital
is suitable for controlled evacuation to a
specified final pressure e.g. for operating an IKA
rotary evaporator.
It can also be used for classical separation, filtration or drying in
the laboratory.
With an appropriate vacuum controller (e.g. VC 10) or with a ro-
tary evaporator (e.g. RV 10 auto), the Vacstar digital can be oper-
ated automatically, for automatic boiling point detection, sched-
uled pressure-time curves or programs from the solvent library, for
example.
Intended use: Tabletop device
if modifications are made to the device or parts of the device
by third parties!
if the
device is
operated in
contravention of
the
safety
instructions!
