MaxQ 7000
The Thermo Scientific MaxQ 7000 series of bench top, water bath shakers
are available in either analog or digital control configurations:
•
SHKA7000, SHKA7000-1CE: control temperature by a
Proportional/Integral/Derivative (PID) 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.
•
SHKE7000, SHKE7000-1CE: control temperature, time and speed by
a Proportional/Integral/Derivative (PID) microprocessor-based
controller that is adjustable on a keypad in 1 rpm increments with
switches. Flashing display indicates power interruption. Pressing any
key will clear display. Speed and time set points are automatically
reactivated after power is restored. Audible and visual signals indicate
when temperature deviates more than 2°C over set point-unit will
automatically shut down. Audible and visual signals indicate when
water level is too low.
Temperature range: SHKA7000, SHKA7000-1CE, SHKE7000,
SHKE7000-1CE, 5ºC above ambient to 65°C with accuracy in flask at
37°C ±0.2°C. Cooler temperatures are attainable using the optional cooling
coil.
In addition, all versions offer:
•
Seamless stainless steel bath chamber with rounded corners
•
Space efficient tubular heaters
•
Set points are retained by non-volatile memory that automatically
reactivate after power is restored
•
User adjustable over temperature thermostat controls temperature if
main controller fails
•
½ inch (1.27 cm) triple eccentric orbital drive
•
6 permanently lubricated ball bearings
Note Propylene glycol must be used as the media instead of water at
temperatures above 90°C.
•
35 lb (15.9 kg) platform load capacity at safe speeds less than 400 rpm
for SHKA7000/SHKA7000-1CE and less than 500 rpm for
SHKE7000/SHKE7000-1CE
