Amerex Instruments Gyromax 747R Refrigerated Orbital Incubator Shaker
The GYROMAX 747R Orbital Incubator Shaker is designed to accommodate as many
clamps of a given size as that in a chest-type shaker, but have the advantage of accommodating
shelves for incubation and the stacking of two units to save space. The double-walled 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 4oC to 80oC.
Independent high and low limit thermostats protect the chamber from overheating and overcooling.
The timer is programmable for up to 99 hours 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, plate holders, and a 30-
port gassing manifold that permits direct gassing into flasks or other vessels. 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.
