Bar code labels must be printed on good quality label stock and must meet the
following specifications:
• 0.25 inch minimum quiet zone on each end
• 0.01 inch (10 mils) minimum narrow bar width
• 2:1 to 3:1 wide to narrow bar ratio
• 0.5 inch minimum bar length
• 2 inch maximum label length
• 1.25 inch maximum label width
• Maximum possible contrast between bars and background label
CELL-DYN 4-digit Code 39 bar code labels, in rolls of 1000 labels each, can be
ordered with list number List Number 99650-01. These labels may be used for
positive specimen identification when laboratory-generated bar code labels are
unavailable.
CAUTION: Ensure that specimen has been properly identified before
placing bar code labels on specimen tubes.
The following two guidelines should be observed when placing bar code labels on
specimen tubes (refer to Figure A.1):
1. All labels should be placed on the tubes securely and without flaps sticking
out. Refer to the following figure.
2. The bar code label should be placed on the tube just below the stopper with
the bars perpendicular to the length of the tube. This will ensure that the
entire bar code can be viewed through the slot in the rack as the tube rotates.
Be sure that at least 0.10 inch (about 1/8 inch) of space is left between (a) the
bar code symbol and the bottom of the rack slot and (b) between the bar code
symbol and tube cap. This spacing will satisfy the "quiet zone" requirement.
Refer to the following figure for proper bar code placement.
