SAMPLE
TRAY
| The
Sample Tray is located in the
center of the working area; 60
samples, standards or controls
can be easily inserted in the
proper positions, identified by a
progressive number. Positions can
be reserved for off-scale
dilutions and are identified by a
red line. The sample tray is
easily removed for loading and
unloading of samples. |

REAGENT
TRAY
| The
Reagent Tray can contain up to 18
reagents, temperature controlled
for stability by a Peltier, which
is located in the left side of
the working area. A computer
controlled needle, connected to a
high precision micro syringe
allows for sample and reagent
pick up. The needle also senses
reagent levels. |

REACTION
CUVETTES
The
Reaction Cuvettes are located
around the Sample Tray. A
computer controlled needle
connected to a high precision
micro syringe, picks up the
sample and the reagents. After
preheating, in a coil positioned
in the body of the needle arm,
they are inserted into a reaction
cuvette that is temperature
controlled up to 50°C. A proper
wash cycle between samples
ensures there is no carry-over
from the previous sample.
Possible carry-over
can be measured and corrected via
the software. |

COLORIMETER
As
soon as the analysis program is complete,
a second needle connected to a
peristaltic pump is activated. The needle
is inserted into the cuvette. Then sample
is then pumped into a temperature
controlled flow cell where the O.D. is
detected by a colorimeter that
automatically selects the right
wavelength. A proper flow cell wash cycle
ensures there is no carry-over from the
previous sample. Optional flow cell
lengths are available for
greater resolution. |
