When looking for a basic, fixed speed vortex mixer with a small footprint for your limited bench space, look no further than the Globe Scientific GVM-MINI! Despite its small size, the GVM-MINI has a wide, stable base to remain in place when in use. When you press your tube down on the top cup, the 3000rpm and small 4.8mm orbit create a ‘vibratory' motion to quickly and effectively mix most tube sizes.
