Titrating, dosing, dispensing, diluting, precision
pumping or preparing standards: The versatile 765 Dosimat
can perform all these tasks.
High-Precision Titration: The
765 Dosimat's keyboard and the stepless manual setting
of the dispensing rate allow titrations to be performed
very fast or very slow, using very small volume increments.
As soon as the endpoint is reached, the large backlit
display shows not only the volume with a resolution of
0.001 mL but the result can also be calculated using
the built-in formula.
The 765 Dosimat as a Precision Pump
There is
a whole range of applications for the 765 Dosimat in
synthesis laboratories and pilot plants, where it plays
the role of an "electronic dropping funnel" in
applications such as:
- Pulse-free dispensing even of corrosive liquids with
rates between 0.001 mL/min and 150 mL/min.
- pH- or temperature-controlled dispensing together
with the 691 or 713
pH Meter and the 692
pH/Ion Meter.
- With two 765 Dosimats, continuous tandem dispensing
is possible (maximum dispensing rate 7.6 L/h).
Pipetting, Diluting, Dispensing
For the auxiliary
operations pipetting, diluting and dispensing, the 765
Dosimat is equipped with the PIP, DIL and DIS modes.
The pipetting equipment available as an option allows
this work to be performed rationally with volumes between
0.7 and 10 mL.
Preparation of Standard Solutions
The 765 and 776
Dosimats, combined with a balance, allow the automatic
preparation of standard solutions: Simply weigh out the
approximate amount of the substance to be dissolved and
transfer the weight to the Dosimat, which then calculates
the amount of solvent needed and dispenses it.
A Wealth of Expansion Possibilities
The 765 Dosimat
is equipped with an RS 232C data interface as standard,
which can be used for connecting a balance, a printer
or a computer. Via a computer, all functions of the 765
Dosimat can be remotely controlled, every parameter can
be set and recalled together with the dispensed volume
and the current instrument status.
The 765 Dosimat
is also available with an analogue output, e.g. for the
plotting of the dispensed volume against time in pH stat
work (option). Via the external dispenser contact, dispensing
can be controlled by means of a push-button cable or
a TTL signal.
Automated Validation
For the automatic
validation of the dosing system, the 765 Dosimat is connected
to a balance via its RS 232C interface. The optional Dosing
Test software controls the automatic dispensing of
liquid into a pre-tared vessel placed on an analytical
balance. The volume of the dispensed liquid is then calculated
and compared with the set volume. The validation report
conforms to GLP and is printed on the connected printer.
Summary: Versatile dispensing instrument with automatic
stopcock switching, for titrating and dosing operations
in the
laboratory. The keypad provides access to the following
functions: automatic preparation of standard solutions;
pipetting, diluting and dispensing; calculation of results.
A wide range of application possibilities as an «electronic
dropping funnel» arise in the synthesis lab and
the pilot plant. Balance, printer or a computer can be
connected via the RS 232C data interface.
