rotating shaft of the burette assembly (Figure 4-3). The rotating shaft on the burette is held
secure in one hand, and using the knurled knob at the base of the syringe barrel, the syringe
is nger-tightened into place with the other hand (Figure 4-4).
The top portion of the burette handle displays a graduated scale with an indicator show-
ing the relative position of the syringe plunger during an experiment. Note that the indica-
tor must be in the fully raised position before installing a loaded syringe into the burette.
For more information on lowering and raising the plunger, refer to Chapter 5: Software
Description.
The bell-shaped upper portion of the burette
assembly has three notched keys for correct
orientation in the instrument. The burette
is installed by carefully guiding the shaft,
needle rst, into the top opening of the calo-
rimeter (Figure 4-5) and lining these notches
up with the three locking posts located in the
mounting ring at the top. The burette handle
is then gently pressed downward, rotated
slightly clockwise, and released to secure the
burette in place. Removal of the burette from
