6.3.1 Equipping the titration vessel with an oven
The titration vessel is equipped in a similar way to that for aspiration with a Dosino, see
page 116. The gas outlet of the oven is connected to the tip. Take care that connection
between the oven outlet and the titration vessel is short, as otherwise condensed water
may form in the tubing!
If you use the 6.1830.000 heatable outlet tubing then you require 6.1446.170 stopper for
the inlet tip.
If in addition to the gas inlet from the oven you want to use a Dosino for aspiration then
the aspiration tip is inserted on the joint opening and the gas inlet is fitted with A.254.0104
seal which is placed in the screw cap instead of the septum; the screw cap is then
screwed down; see below.
If you use the 6.1830.000 heatable outlet tubing then you should use A.254.0102 seal
(instead of A.254.0104) for the gas inlet.
If you require an additional opening for injections then 6.1465.320 titration vessel is avail-
able; it has two side-mounted screw threaded openings.
