Product Profile
The Thermo Scientific MaxQ Mini 4450 bench top, incu-
bated shakers are available in either analog or digital con-
trol configurations:
•
Analog shakers: SHKA4450, SHKA4450CC,
SHKA44500-1CE and SHKA4450CC-1CE: con-
trol temperature by a Proportional/ Integral/
Derivative microprocessor-based controller.
Solid-state control maintains time and speed
and is adjustable with rotary dials. Analog
tachometer displays speed in RPM, verifying
accuracy of speed setting.
•
Digital shakers: SHKE4450, SHKE4450CC,
SHKE4450-1CE and SHKE4450CC-1CE: con-
trol temperature, time and speed by a
Proportional/Integral/Derivative (PID) micro-
processor-based controller that is adjustable
with membrane switches on a keypad in 1 rpm
increments. Flashing display indicates power
interruption. Pressing any key will clear display.
Non-volatile memory maintains speed and time
set points in the event of a power interruption.
Speed and time set points are automatically
reactivated after power is restored.
•
Models SHKA4450CC, SHKA4450CC-1CE,
SHKE4450CC and SHKE4450CC-1CE include a
cooling coil to allow a below ambient tempera-
ture in the shaker's chamber.
•
Temperature range 5ºC above ambient to 80ºC.
•
Drive interrupt halts shaking action when lid is
opened.
•
All set points are retained by non-volatile memo-
ry that automatically reactivates after power is
restored.
•
Visual, user adjustable over-temperature safety
signal with independent thermostat controls the
heat if main controller fails.
•
3/4 inch (1.9 cm) triple eccentric orbital drive.
