Sample Loader
Sample Loader Description
Section 13
The
Sample Transport Assembly
consists of pneumatic-actuated arms that move
the racks in an orderly process through the sample mixing, bar code reading, and
aspiration stages of the processing cycle.
There are two
Sample Tube Sensors
at the two Sample Mixing Stations. The
sample tube is sensed at the first sample Mixing Station (tube position 3) and again
at the second Sample Mixing Station (tube position 4). The sample loader will
continue to advance racks if there are no tubes present at both mixing stations.
The
Sample Mixing Assembly
consists of two tube grippers on the Mixing Block.
The block is raised pneumatically and the mixing rotation is done by a stepper
motor.
The
Bar Code Reader
is an LED type and can accommodate the following
formats: Code 39, Code 128, CODABAR, and Interleaved 2 of 5. On the SL model,
the Bar Code Reader is located on the Sample Loader directly in front of the
aspiration needle/spinner assembly.
A
Power Cable
connecting the Sample Loader with the Analyzer provides power
from the Analyzer to the loader. An
Interface Cable
connecting the Analyzer and
Sample Loader provides bi-directional communication.
Bar Code Label Placement
Tube Labels
All labels should be placed on the tubes securely. Flaps or edges should not be
sticking out. Labels should not cover the cap (high collar) or the bottom (tail) of the
tube. Labels should be placed between 3/4 inches from the bottom of the sample
tube and 3/4 inches from the top of the tube. (See Figure 13.3.) Layering more than
3 labels may prevent the bar codes from being read.
NOTE:
Refer to Appendix A for complete information on Bar Codes, Check
Digits, and specifications.
