Chapter 4 Testing samples
55
OsmoTECH XT Single-Sample Micro-Osmometer User Guide
Test results are stored in the Results database.
NOTE: If you want to cancel a test, you can
withdraw the sample operating cradle at any
time. If an error occurs during a test, you will
hear a beep, and a message displays on the
screen.
Preparing the instrument for the next test
1. Withdraw the operating cradle and remove the
sampler from the cradle.
2. Grasp the sampler tip and depress the plunger to help
remove it. Discard the sampler tip.
3. Wipe the plunger tip with a soft, non-lint, non-ionic
paper, being careful not to dislodge the Teflon® tip.
4. Insert a clean, dry chamber cleaner into the sample
port until you feel a positive stop. Rotate four or five
times in one direction while applying forward
pressure.
5. Withdraw the cleaner and use the other end to clean
the probe again in the same manner.
Leave the cleaner in the sample port until the next
test.
NOTE: If you want to confirm that you cleaned the
instrument correctly, remove the cleaner and
inspect it. Each end of the cleaner should
have a small puncture hole, indicating proper
cleaning. If you have finished testing samples
for the time being, insert the cleaner back
into the port after inspecting it.
6. Test more samples or exit:
• To test additional samples, repeat this procedure
beginning with step 4 on pg. 53.
• If you have no more samples to test and if you are
logged into the instrument, press the Login button
to log out. Confirm that the Login button changes
from blue to gray or orange.
4.6 Scanning barcodes
You can scan the barcodes on samples. This eliminates
entry errors and speeds the logging process.
1. Make sure you’ve enabled the barcode
(see Turning on the barcode scanner).
2. Hold the control with its label positioned a few inches
in front of the barcode scanner.
The scanner reads the barcode and populates the ID
and Control Name fields on the CONTROLS screen.
