The Rotating Mixer provides gentle to vigorous mixing of laboratory samples up to 50ml. With adjustable speed control and tilt angle, the Rotating Mixer is ideal for a variety of applications, from mixing blood samples to the preparation of homogenous dispersions. Three rotisserie tube holders are included for mixing all common laboratory sample tubes and each individual tube holder is rubber coated to provide a secure grip, preventing any wobble or loosening during mixing at high speeds. For more intense mixing, a unique reversing mode is available. In reversing mode, the mixer rotates for up to 360° then stops and rotates in the reverse direction. This back and forth motion occurs repeatedly until the set time has expired.
