The Wizard features a small footprint, low profile, and ergonomic design. Three anti-sliding feet absorb vibration and enhance stability. The infrared system detects the presence of a test tube and starts vibration automatically — no pressure is required to maintain vibration. Adjustable speed lets you set at low speeds for gentle mixing or high speeds for more vigorous mixing. Wide operating ambient temperature range makes mixer ideal for cold rooms or incubators. What's included: standard pop-off cup for single test tube, and 6-ft cord with plug.
