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.

Training

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.

Optional are:

  • 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).
