Sealed Fluid Bath

NOTE: For Sealed Fluid Bath installation instructions, refer to TRIOS software online Help.
CAUTION: Never place any lower geometry into the bath if its temperature is cooler than that of the
bath. Placing a geometry into a warmer bath will result in expansion of the geometry during use.
After expansion, the geometry may not be removable without damaging the bath. We suggest that
you partially insert the geometry by placing a phenolic spacer between the upper lip of the lower
geometry, and the surface of the bath. Allow the lower geometry temperature to match that of the
bath, then remove the spacer and fully insert the lower geometry.
MISE EN GARDE: Ne placez jamais une géométrie inférieure dans le bain si sa température est plus
froide que celle du bain. Placer une géométrie dans un bain plus chaud entraîne la dilatation de la
géométrie pendant son utilisation. Après la dilatation, il n'est plus possible de retirer la géométrie
sans endommager le bain. Nous suggérons d'insérer partiellement la géométrie en plaçant une
entretoise phénolique entre la lèvre supérieure de la géométrie inférieure et la surface du bain. Lais-
sez la température de la géométrie inférieure correspondre à celle du bain, puis retirez l'entretoise et
insérez complètement la géométrie inférieure.
The Sealed Fluid Bath offers precise control of sample temperature using a closed fluid recirculating sys-
tem. The operational range of the Sealed Fluid Bath is –10°C to 105°C. Thermally controlled fluid, sup-
plied by a circulator, flows through the bath and is used to regulate the temperature. The lower geometry
mounts within the bath well and attains thermal equilibrium with the surrounding bath. The temperature of
the lower geometry is measured by the bath PRT, which mounts through the bath well into the motor.
The circulator (as supplied by TA Instruments) is connected to, and is under the control of, the test station
and software. The circulator also has its own fluid temperature regulation, which can be used as the tem-
perature control loop for the bath.

NOTE: The temperature range of the Sealed Fluid Bath depends on the fluid in the circulator. TA Instru-
ments recommends a fluid that is a 50/50 mixture of water and laboratory grade Ethylene Glycol. This will
give an effective range of –5 to 105°C.
