1 Introduction

1.1 Instrument description

The 803 Ti Stand with a magnetic stirrer and a built-in pump is part of the
Titrando system. It is mainly used for volumetric Karl Fischer titration
together with a Titrando.
The titration stand is directly connected to the Titrando via an MSB con-
nection cable.
With the integrated membrane pump it is possible to aspirate the titered-
out solution and to add a new solvent without having to open the titra-
tion cell.

3.1 Setting up the instrument

3.1.1 Packaging
The instrument is supplied in protective packaging together with the sepa-
rately packed accessories. Keep this packaging, as only this ensures safe
transportation of the instrument.

used in explosive environments.
Place the instrument in a location of the laboratory which is suitable for
operation and free of vibrations and which provides protection against
corrosive atmosphere and contamination by chemicals.
The instrument should be protected against excessive temperature fluctua-
tions and direct sunlight.

3.2 Mounting the 803 Ti Stand

Mounting the KF titration stand as follows:

1 Screw the 6.2001.060 stand plate with the accompanying four

screws tightly to the bottom of the instrument.

Install the KF titration cell as follows:

1 Screw the 6.2013.010 clamping ring tightly to the support rod.

2 Mount the 6.1414.030 vessel lid of the KF titration cell to the sup-
port rod. Keep the locking lever pressed down until it can be released
at the desired position.

3 Fasten the 6.1415.220 (or 6.1415.250) titration vessel with a

6.1903.020 (or 6.1903.030) stirring bar inside on the vessel lid. Fold
back the holding bracket upwards while doing so. The markings on
the vessel lid and on the plastic ring must be aligned above one
another.

4 Press the holding bracket downwards in order to fix the titration ves-
sel. The levers of the holding bracket must enclose the pins of the
plastic ring on the titration vessel in order to ensure a secure hold.

5 Adjust the height of the KF titration cell by pressing the locking lever.
It should almost touch the surface of the stirrer. The position can
now be fixed by readjusting the clamping ring.
Once the height of the KF titration cell has been adjusted correctly,
the entire cell can be raised and swiveled to the right as required by
pressing the locking lever.

3.3 Connecting the 803 Ti Stand

Connect the titration stand as follows:

1 Exit the control software.

2 Connect the connection cable of the titration stand to one of the

sockets marked with MSB on the rear of the control device.

Mount the waste bottle as follows:

1 Equip the 6.1602.105 bottle attachment with the 6.1446.040

threaded stopper, the 6.1808.050 tubing adapter and the
6.1446.090 stopper.

2 Plug the 6.1623.000 overflow protection from below into the

6.1602.105 bottle attachment (the opening, the 6.1808.050 tubing
adapter is plugged in).

3 Screw the 6.1602.105 bottle attachment onto the 6.1608.030 waste

bottle.

4 Cut the 6.1801.120 PVC tubing into two halves and use one to aspi-
rate.

5 Fasten the one end of the aspiration tubing to the tubing adapter,
the other to the connection nipple for the waste on the rear of the
titration stand.

6 Insert the 6.1819.050 cannula through the 6.1446.090 stopper into

the waste bottle.

7 Screw the 6.1805.200 PTFE tubing into the 6.1446.090 stopper.

8 Screw the 6.1543.120 aspiration tip to the other end of the PTFE
tubing.

9 Insert the aspiration tip down to the bottom of the titration vessel to
be emptied and fasten it to the titration vessel lid.

NOTICE

The waste bottle should periodically be emptied.

Mounting the equipment for aspirating solvent

Mount the solvent bottle as follows:

1 Fill the 6.1609.010 adsorber tube and the 6.2811.000 molecular

sieve with cotton.

2 Use the other half of the 6.1801.120 PVC tubing previously cut in
two pieces for aspirating the solvent. Fasten the one end of the tub-
ing to the lower end of the adsorber tube, the other end to the con-
nection nipple for aspirating the solvent.

3 Equip the 6.1602.105 bottle attachment with the 6.1446.040

threaded stopper and the 6.1609.010 adsorber tube.

4 Secure the adsorber tube with the 6.2023.020 SGJ clip.

5 Insert the 6.1819.030 cannula into the last open hole (with medium-
sized diameter) of the 6.1602.105 bottle attachment.

6 Screw the 6.1602.105 bottle attachment onto the solvent bottle.

Instead of the 6.1608.023 amber glass bottle, other reagent bottles
with GL45 thread can be used (e.g. RIEDEL DE HAEN (1 liter), BAKER).
For other bottles another bottle attachment or an additional thread
adapter have to be used.
