S-Monovette® is a blood collection system that combines two blood collection techniques – aspiration and vacuum. The S-Monovette® is suitable for all vein conditions and achieves an optimal sample quality, thereby producing the best results. The aspiration technique is a gentle technique for routine blood collection. Using the vacuum technique, a 'fresh' vacuum is always available.

S-Monovette® PFA preparation (3,8% citrate buffer, 0,129 mol/l, pH 5,5) was specially developed for the Siemens Healthineers PFA measuring system, to allow precise analysis of thromocyte function.
