System User's Manual
Both methods are explained in Figure 10.
Prior to placing vials into stations, visually inspect all vials for positives. Evidence
of microbial growth includes hemolysis, turbidity, and excess gas pressure (caus-
ing the vial septum to bulge outward).All such vials should be treated as posi-
tives; they should be stained and subcultured.
To
enter
new vials in the instrument:
Take the new cultures to the instrument. Open the instrument door. Follow the
procedure shown in Figure 10.
NOTES
When scanning vial barcodes, place the vial in the alignment
block in front of the scanner with the barcode label facing the
scanner. If necessary, rotate the vial slightly so the scanner can
read the labei.The system beeps once to indicate a good scan.
Station assignments are calculated by the system software to
balance the rotor. In order to maintain rotor balance, you
should always enter vials into the instrument as described in
Figure 10, and place the vials where the system indicates.
When inserting vials into stations, carefully push the vial into
the station. Press against the shoulders to insure that the vial is
fully seated in the station.
Once the vials are placed in stations, they should not be twisted
or turned.Vials should not be removed except in the following
conditions:
• Removal of positive
• Removal of negative
• Reassign if station becomes bad
• Identification of anonymous vials
Any vial reassigned to a new station should be subcultured
immediately.
