English to French Medical Medical: Instruments analyseur

c'est un titre. Voilà le paragraphe qui suit :
When blood collection tubes that contain physical barriers are used, extra care should be exercised to ensure that the barrier is tightly packed. Loose particles from the barrier could coat or plug the sample probe, flow cell, chemistry modules, electrolyte injection cup (EIC), or cuvette wash station.
Merci d'avance.
