4. SYSTEM DESCRIPTION

4.1 Analyzer unit

The SRT 10/II ESR analyzer is an automatic instrument controlled by a microprocessor and
exclusively employed for analysis of the erythrocyte sedimentation rate. It's total absence of
commands, its precision and its ability to obtain the result already corrected to a temperature
of 18°C (according to Manley) in either 15, 30 or 60 minutes make it the most innovative and
versatile system for this kind of analysis. It constantly and simultaneously scans 10 test
tubes, which are custom-made for ESR with this system.
SRT 10/II follows the sedimentation of each sample independently to each other, memorizing
levels for the whole period of analysis. The instrument can be used for random and
continuous loading of samples to a capacity of 10 test tubes each time. When a sample has
been analyzed, it can be replaced by another, so it is possible to analyze up to 40 tests / h.
SRT 10/II has been developed to simplify ESR analysis, avoiding sample manipulation and
operator 's infection risk. To carry out the analysis, the operator puts the sample test tube into
the instrument. The result appears on the display in the selected analysis time. This feature
allows the instrument to be used directly on the ward, in the blood sample collection
department and in small laboratories. In carrying out the analysis SRT 10/II measures the
room temperature and converts the result to the reference temperature of 18°C. (In
accordance with Manley table).
The results conversion is necessary to avoid substantial variations of values due to different
room temperatures.

4.2 Pre-Indication of the results

Only 9 minutes after putting the sample in, before the end of analysis, the SRT 10/II can
show on the display messages indicating a prediction of the result.
These symbols appear on the display in the same position of the sample channel.
