The SARSTEDT S-Monovette® is an innovative, enclosed multiple-sampling blood collection system. Ranging from 1.1 ml to 1.8 ml, S-Monovette® tubes collect over 40 percent less blood volume than traditional tubes. These small blood volumes are drawn directly and gently into the S-Monovette® system containing a range of additives and can be processed directly. Significantly reducing laboratory diagnostic blood loss can reduce hospital-acquired anemia and improve patient outcomes.
