AUXILIARY FUNCTIONS
8.1.1 Prime Burette
The
Prime Burette
option is used to mechanically fill the burette before starting a set of
titrations. The priming process consists of several cycles of filling and emptying the burette
with titrant.
Two rinse cycles of burette are shown in the figure below. The dispensing tube is connected
on the right side and the aspiration tube on the left side.
Note: Before starting this operation, the aspiration tube must be inserted in the titrant
bottle. A waste container should be placed under the dispensing tip to collect the
waste solution.
To prime the burette, select
Prime Burette
from the
Burette
screen. Enter the number of
rinses and press .
The number of burette rinses can be set between 1 and 5 (we recommend at least three
rinses to assure that the air bubbles are completely removed).
