Ohaus brings you a line of heavy duty incubating shakers with their ISHD series. Incubating Heavy Duty Orbital Shakers offer exceptional temperature uniformity and are designed for a variety of shaking and incubating applications. The exclusive Opti-Flow Forced Ventilation System utilizes twin induction or a single large fan. Air is deflected around & not directly on samples, creating a circular flow of air ensuring uniformity. For repeatable results, the exclusive Accu-Drive shaking system ensures speed accuracy. The Triple Eccentric Drive provides consistent shaking motion throughout the entire speed range. The chambers for the ISHD23HDG and ISHD23CDG units are large enough to hold 2 x 6 L Erlenmeyer flasks with optional clamps and platform.
