The Vortamix Mini Vortexer from Argos Technologies is an unbelievably compact, yet powerful instrument engineered to mix tubes quickly and easily. The vortexing motion is activated by placing a tube on the gasket cap and then pressing down lightly. The innovative design of the gasket cap allows centrifuge and test tubes up to 30 mm in diameter to be mixed with very little effort – including 50mL conical tubes.
