Intended Use
InSight V-CHEM Veterinary Chemistry Analyser provides quantitative in-vitro
determination of clinical chemistry analytes in lithium heparinised whole blood,
heparinised plasma or serum. The entire analysis requires 100µl of sample and is capable
of providing results in 8 minutes for whole blood and 7 minutes for serum and plasma.

Major Components
•
Variable Speed Motor - Drive and control the supporting reagent disc
•
Spectrophotometer - Measures the optical signal of the disc detection cuvette
•
Microprocessor - Used for system control and data acquisition calculation
•
Colour Touch Screen - Interactive medium between operator and analyser
•
External Printer - Assembly options
Each reagent tray is a separately packed disc. The disc diameter is 7.8cm, with a thickness
of 0.7 cm. The body of the reagent disc consists of a Plexiglas which contains the
lyophilised reagent beads in the colorimetric cuvettes placed around the disc. The
polycarbonate film is used as the encapsulation. For chemical analysis, blood samples
(lithium heparin anticoagulant whole blood, lithium heparin anticoagulant plasma or serum)
need to be pipetted into the corresponding well and the foil tab removed to release the
diluent. The reagent disc is placed into the analyser drawer for chemical analysis. The
reagent disc is rotated by a motor, ensuring the whole blood is separated into plasma and
blood cells (skip this step for serum and plasma samples). At the same time, the reagent
disc is heated to 37°C. The plasma (serum) and diluent are precisely quantified in the
quantitative slot of the reagent disc; thereafter, quantitative plasma (serums) and diluents
are thoroughly mixed in the mixing tank. Finally, uniform dilute plasma (serum) samples
are distributed to each colorimetric cuvette around the reagent disc for chemical reaction
and detection. The above operations are based on the design of the micro-channels in the
reagent disc, which is automatically completed in the reagent disc through the coordination
of motor speed adjustment.
