Control Cuvette

The filled cuvette should be visually inspected for
air bubbles. Small air bubbles around the edge do
not influence the result.
Place the filled cuvette into the cuvette holder
immediately and push it into measuring position.
The filled cuvette should be analyzed immediately
and at the latest 10 minutes after it has been filled.
Filled cuvettes are to be kept lying down. Filled
cuvettes should be inspected for airbubbles, which,
if present, can produce erroneously low readings.
Small air bubbles around the edge do not influence
the result.
After 15–45 seconds the result is displayed. If
”ERROR” code appears, turn to ”Trouble Shooting
Guide,” page 14.
The filled cuvette should be disposed of after the
measurment.
Although the reagents are present in the microcuvette
in extremely low quantities, consult local
environmental authorities for proper disposal.
Always handle blood specimens with care as they
may be infectious.
When the measurement procedure has been
completed, turn the photometer´s power switch to
the ”POWER OFF” position.
Venous or arterial blood from tube or syringe.
The cuvette can also be filled with well mixed
venous or arterial blood. Place a drop of blood (or use
a pipette) onto a hydrophobic surface, for example a
plastic film. Introduce the cuvette tip into the
middle of the drop in such a way that the whole
cuvette is filled in one step. It should never be
topped up. For further handling of the cuvette, see
above.
The cuvette can be filled directly from the tube, if
the tube is not to be used for further analyses.
It should be noted that oxygenated blood
which has been agitated over a long period
produces oxygen pressure and viscosity at
higher than normal levels.
The achievement of accurate results for
blood in this condition requires analysis to
be undertaken immediately after the cuvette
has been filled.
