Bar code reader
User Information
Applying labels
One roll of preprinted labels, numbered from 1 to 1000, is
provided with the bar code reader. This roll of labels is designed
for use with the Label Applicator, discussed later in this
section. To purchase additional labels, see your Agilent
consumables and supplies catalog or visit our web site at
www.Agilent.com.
If you have worked as an analyst for more than a day, you have
encountered the problem of sample labels that do not stick to
sample bottles. Rubber bands, transparent tape, putting the
bottle and the (loose) label in a beaker
―
these are some
common “solutions”. But they will not work with bar code
labels. The following hints will help avoid loose labels.
•
Label adhesives have an annealing time during which the
strength of the bond increases. For the Agilent labels, this is
about 20 minutes. Give the label bond a chance to anneal
before you stress it, whether mechanically or by placing it in
a refrigerator or freezer.
•
The
Agilent labels have a slight overlap. Be sure that the tail
of the label is firmly pressed down.
•
The adhesive anneals best when both the label and the bottle
are at room temperature. After the bond has strengthened, it
will retain that strength when refrigerated.
•
It is difficult to stick anything to a wet surface, including the
thin film of moisture that condenses almost immediately on a
bottle removed from a refrigerator.
•
If you do find it necessary to overwrap the label with
transparent tape, apply it smoothly and avoid placing the
ends over the bar code itself.
•
Keep the bottles and the labels clean. This improves both
adhesion and readability. Do not write over the bar code.
Label applicator
The Label Applicator (part number 18587-60530) supplied with
the bar code reader applies Agilent preprinted labels in the
correct position on the vial.
