The Sarstedt S-Monovette® is an innovative, enclosed multiple-sampling blood collection system. S-Monovette® tubes can be gently filled by manual aspiration to minimize shear stress associated with vacuum tubes and I.V. catheters. Compared to untreated syringes, S-Monovette® tubes contain a range of additives and can be processed directly with no transfer, maintaining a closed connection.
