The GYROMAX™ 787/787R orbital incubator features a microprocessor temperature controller, double-walled construction and a 1.5" thick and a double-paned glass window to minimize heat loss. This construction, together with an efficient circulation system, ensures unrivaled optimum temperature uniformity throughout the chamber. The window has an opaque sliding panel to block light from enter the chamber for applications involving light-sensitive materials. The temperature is set digitally and reproducibly and displayed by an LED to 0.1°C. The working temperature range for the 787 is from 5°C above ambient to 70°C for the 787 and 4°C to 70°C for the 787R. An over-temperature cutoff device prevents accidental overheating.

A large, quiet fan ensures air and temperature uniformity throughout the stainless steel chamber. A brushless, maintenance-free drive motor generates speeds from 25 to 400 RPM which are displayed digitally. A fan cools the motor so that it operates at a lower temperature, thereby prolonging its life. A dynamically triple-eccentric drive with counter-balancing weights provides smooth and quiet shaking and there is no need for adjustments as the load or RPM changes.

The shaking stops when the door is opened and resumes when it is closed again. The chamber is constructed of stainless steel and comes with a shelf. The 18.1" x 18.1" platform can accommodate Erlenmeyer flasks up to 4 liters.

Optional accessories include shelves (if two or more are needed), platforms, clamps, and spring racks. The spring rack is designed for holding tubes in a horizontal, angled, or upright position. It can also be used to hold flasks up to 1L without clamps. The rack consists of a 2-tiered grid of springs. The distance between the racks is adjustable so as to accommodate tubes and flasks of different heights. It is mounted on to the platform by four screws.

A programmable timer affords a choice of switching between a continuous run or a timed run up to 99 hours and 59 minutes. For even longer runs, each timed run can be repeated up to 999 times.

Multi-step programming is available. A program can consist of up to 9 steps and for each step you can change the time, RPM and the direction of rotation. For example, shake at 300 RPM clockwise for 60 minutes, then 250 RPM counter-clockwise for 120 minutes, followed by 200 RPM in the opposite direction for another 120 minutes, and repeat as needed. For applications such as the mixing of immiscible liquids or in extraction, the direction of rotation can change every 1 minute for optimum effect. To prevent over-heating, the controller shuts off the heater if the chamber temperature exceeds the set temperature by a pre-determined number of degrees. In case of a power failure, shaking automatically resumes when power is restored.
