Vornado™ mini vortexer, red cup head, 100 to 240V w/EURO adapter, Cat. No.: BM-BV101-R-E, Powerful is the best word to describe this mini vortexer. With a 4 mm orbit and fixed speed of 2800rpm, the Vornado instantly vortexes even the largest samples, including nearly full 50 ml tubes. Despite its powerful motor, the Vornado has a footprint of less than 4×4 inches, allowing it to fit on even the most crowded bench.
