The versatile, end-over-end tube roller and Rotators are designed for mixing samples in both a vertical and horizontal plane. They can be placed in an environment temperature ranges from 5 to 40° and the rotation speed is adjustable, from 0 to 99 rpm. Tube Rollers, Rotators and Rocker are designed to deliver salient performance, accuracy, and reproducible results for all your application needs. - 360° vertical rotating for larger particles longer wavelength mixing - Swinging for culture medium and larger particles medium longer wavelength mixing - Oscillating for small particjes short wavelength mixing - Tube holder assemble discretionary
