The Lorrca ektacytometer
The Laser-assisted Rotational Red Cell Analyser (Lorrca) measures the deformability (changes in elongation) and RBC aggregation & dis-aggregation.
The Lorrca contains the Osmoscan, to measure and visualize RBC elongation in shear stress in an osmolality gradient.
Mid 2018 the Lorrca is enhanced with the Oxygenscan (as ‘add-on’), to measure and visualize RBC elongation in shear stress in an oxygen gradient, during deoxygenation and re-oxygenation.
Table 1. Overview Lorrca product numbers
|Instrument||LORC109230 or LORC109110||Lorrca|
|Oxygenscan||PO2S109500||PO2Scan (to perform the Oxygenscan)|
|Oxygen sensitive spot||PO2S020153||PO2S Luminiphore (1pcs)|
The Lorrca with integrated pO2Scan performs the Oxygenscan.
The Oxygenscan measures the Point of Sickling (PoS) of SCD Red Blood Cells (RBCs).

To enhance the knowledge and improve efficient use of the Lorrca! It is a very ‘open’ instrument, in which the standard-setting can be adjusted according to the study/aim.
- the Operator training (to operate system),
- the Technical training (expert-level, for detailed technical insight) and
- the Chart Analysis training (to excel in analysis of raw data and to gain experience in chart interpretation).
