Test Cuvettes

Tests are performed with single-use disposable test cuvettes (Figure 3). Each test cuvette
contains a finger grip, filling port, optical window, and a vent patch.

A whole blood sample is inserted into a test cuvette by connecting a small syringe containing the
whole blood sample to the filling port and then gently pressing the syringe plunger to dispense
approximately 50 µL of whole blood into the test cuvette. Air escapes from the vent patch at the
end of the test cuvette while the whole blood sample is being inserted. The test cuvette (with the
syringe still attached) is then inserted into the test chamber of the instrument (see page 33 for
details).
Note: Be sure to handle the cuvette either by the edges or by the finger grip. Refer to the
package insert accompanying the test cuvettes for storage and handling instructions.
●
Remove any blood or debris from the exterior of the test cuvette before
inserting it into the test chamber.
●
After filling the cuvette with blood, inspect the vent patches to ensure they
are not bulging out. If a vent patch protrudes, discard the cuvette. Do not
insert a cuvette with a protruding vent patch into the test chamber.
BIOHAZARD WARNING: Any items exposed to human blood, plasma or serum
must be handled cautiously as a biohazardous material in accordance with
laboratory safety practices and federal and local regulations. Federal, state and
local laws and regulations require that hazardous waste be disposed of in a
specific manner. Waste material from the AVOXimeter 4000 which may be
classified as biohazardous include used cuvettes. It is important that steps be
taken to dispose of these materials in accordance with the prevailing regulations
in your location.
