Selectra Pro XS Clinical Chemistry Analyzer, berikut feature-feature dan spesifikasi pada alat:

Processing Center

Sampling probe with integrated mixer and level sensing
The unique sampling probe streamlines sample and reagent level sensing, aspiration and mixing. That reduces complexity, enhances uptime and provides collision protection.

Combined sample and reagent rotor with cooling dome
The rotor ensures optimum temperature and humidity are maintained providing reagent on-board stability and integrity.
• 30 on-board reagent positions (inner ring with 15 cooled reagent positions).
• 25 sample, control and calibrator positions.

Disposable cuvettes
Reduced maintenance and water consumption while improving test turnaround time.

Bar code reader: test requisition, sample and reagent identification
Optional reagent and sample patient bar code further simplifies operations and eliminates potential errors.

Selectra Pro XS Clinical Chemistry Analyzer Operator Interface 

Easy to use
The simplicity of the software allows a skilled technician to operate the Selectra ProXS within an hour. Interactive and intuitive routines lead the operator to the results quickly. The system maintenance instructions are integrated in the software.

On-board Quality Control
QC results are stored in memory and are easily displayed on the screen. The software calculates the mean, standard deviation and coefficient of variation. Validation using Westgard rules and a display of the Levey Jenning plot are also included.

Three reagent system
The software supports a ‘three reagent system’. This feature makes the Selectra ProXS the ideal platform for special applications or sample pretreatment steps.
