September 2021—Sarstedt introduced S-Monovette Lithium-Heparin Gel blood collection tubes, which feature a polymer-based gel layer with improved rheological properties to reduce centrifugation time. Tubes can be centrifuged in as few as four minutes to yield properly separated and stable plasma ready for immediate testing, the company says. The tubes are offered in three volume and size options: 2.7 mL (13 × 75 mm), 4 mL (13 × 75 mm), and 4.9 mL (13 × 90 mm).

S-Monovette tubes can be operated using a vacuum or aspiration technique and connect to corresponding Sarstedt safety needles.
