NOTE:
To run this instrument properly, it is important
that you read and follow the instructions in this
chapter.
WARNING:
Handle all biohazardous materials
per established good laboratory practices and
follow your institution’s exposure control plan.
Persons handling human blood and body fluid
samples must be trained in bloodborne hazards
and observe universal precautions. Universal
precautions are an approach to infection
control, where all human blood and body fluids
are treated as if known to be infectious. Use
personal protective equipment such as gloves,
gowns, etc., to prevent exposure. Store
biohazardous materials in regulated waste
containers and dispose of these materials in a
safe and acceptable manner in compliance with
all country, state and local requirements.
WARNING:
If a biohazardous material is spilled
on or inside the equipment, decontaminate the
equipment using a 1% bleach solution, or as
outlined by your laboratory’s policies and
procedures (see
WARNING:
To avoid injury or fire hazard, do
not operate this product in an explosive
atmosphere.
IMPORTANT:
Do not test samples until controls and/or
reference solutions yield values in the expected range.
IMPORTANT:
Annual preventative maintenance by an
Advanced Instruments-trained service engineer is
strongly recommended to ensure optimal performance
and maximize the life of the instrument.
5.1 Best Practices for Handling Samples
Verify calibration daily using Advanced Instruments
controls (see
Running Instrument Calibration
and
•
The turntable holds up to 20 samples to be tested.
The instrument is designed to acquire samples from
the following glass or plastic tubes 75 mm to 100 mm
in length.
•
Insert tubes and adapters into the turntable so that
the bottom contacts the tabs at the bottom of the
turntable tube holders.
WARNING:
Remove all caps from the tubes.
The pipettor tip is not designed to pierce
tube caps. Failure to remove the caps can
result in the OsmoPRO MAX halting
operation when the pipettor contacts the
cap, and could damage the pipettor.
•
Only use controls before the expiration date marked
on the package. Controls used after the expiration
may have degraded to the point where they provide
unreliable results.
•
Avoid testing in drafty areas.
•
Verify that the sample is thoroughly mixed.
•
Visually inspect samples for clots.
•
Keep sample fluids covered if possible prior to loading
- remove caps prior to testing to minimize
evaporation or contamination.
•
Do not store open ampules with a sealing film.
•
Make sure there are no bubbles in a sample.
Air bubbles may produce erroneous results. If an air
bubble is observed, discard the sample tube and
dispense a new sample into a new sample tube.
•
Treat all samples, standards, and reference solutions
uniformly before the test.
•
Discard control ampules after use.
