The 747/747R design is similar to that of the corresponding 737/737R, but offers more capacity. They can accommodate just as many or more flasks of a given size than the chest type 767/767R. Moreover, they also offer advantages over chest type shakers such as a shelf, a smaller footprint, and the ability to stack two units.

Features

The GYROMAXTM 747 and 747R Orbital Incubator Shakers are designed to accommodate as many clamps of a given size as that in a chest-type shaker, but have the advantage of accommodating one or more adjustable shelves for incubation and the stacking of two units to save space. The doublewalled construction, with 1.25" of insulation and a triple-paned, evacuated viewing glass window, minimizes heat loss. This construction, together with an efficient circulation system, ensures unrivaled optimum temperature uniformity throughout the chamber.

 

The temperature is microprocessor controlled and is monitored accurately by a Pt-100 RTD. It is set digitally and reproducibly from a membrane keypad and displayed by an LED to within 0.1oC. The working temperature is from 7oC above ambient to 80oC for the 747, and 4oC to 80oC for the 747R. Independent high and low limit thermostats protect the chamber from overheating and overcooling. The timer is programmable for up to 99 hours and 59 minutes or for continuous operation.

 

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 that is displayed digitally. At the same RPM, the standard shaking orbit of 25 mm provides a higher oxygen transfer rate (OTR) compared with shakers with a 19 mm orbit because OTR is directly proportional to orbit size. The motor incorporates a built-in fan that lowers its operating temperature and thereby prolongs its life. A triple-eccentric drive with counter-balancing weights provides smooth and quiet shaking without the need for adjustments as the load changes. The shaking stops when the door is opened. The chamber lamp is turned on and off with a switch on the control panel. The 26” x 21” platform can accommodate Erlenmeyer flasks up to 6 liters.

 

Optional accessories include: platforms, clamps, spring racks, tube racks, and plate holders. Platform holes are drilled to accommodate the different clamps purchased. 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 1-liter without clamps. The rack consists of a 2-tier grid of springs. The distance between spring racks is adjustable to accommodate tubes and flasks of different heights. They are mounted onto the platform by four screws.
