Equipment
- Erythrodeformeter
Instrument developed in our laboratory and used for determining dynamic and stationary viscoelastic parameters of red blood cells by laser diffractometry. The alterations produced in vivo by pathologies such as diabetes, arterial hypertension and anaemia, and produced in vitro by diverse treatments (glycosilation, lectins, etc.) are studied. - Erythroaggregometer Instrument used for analysing association and dissociation kinetics of erythrocyte assembly (aggregated or agglutinated) by laser back scattering.
