Advanced 3750 Reciprocating Shaker is designed for a wide range of
applications including cell cultures that require accurate and repeatable results. The
microprocessor control provides consistent uniform shaking while safely ramping to the
set speed.
Operating Features:
The shaking system continuously monitors shaking speed and maintains set-point, even
under changing loads. When unit is set to a speed above 100rpm, the speed accuracy is
± 1% of set speed. When set under 100rpm, speed accuracy is ± 1rpm.
Microprocessor control:
The variable speedmicroprocessor control provides consistent
uniform shaking action.
Single eccentric drive:
Permanently lubricated ball bearings and maintenance free,
brushless DC motor provide reliable service and continuous duty operation.
LED display:
Touch pad controls with easy-to-read, independent LED displays for speed
and time allow operator to view both settings at once. Provides repeatable and accurate
results every time and is easily visible across lab benches. Timer will display elapsed
time or, when programmed to user defined limit, will shut off unit when time reaches zero.
Display will show last used settings, even after power has been turned off.
RS-232 interface:
Provides two-way communication for data logging and unit control.
Speed calibration mode:
Allows user to automatically recalibrate speed display.
Safety Features:
Load sensor:
A built-in load sensor detects unbalanced conditions and automatically
reduces rpm to a safe speed to protect samples.
Overload protection:
Audible and visual signals will activate when system detects an
obstruction or overload of the tray.
Speed ramping feature:
Slowly increases speed to desired set-point to avoid splashing.
Audible alarm:
In timed mode, alarm will sound when the time reaches zero. Alarm has
optional mute function which can be set from the touch pad control.
Spill-resistant design:
Channels fluids away from internal components.
Operating Conditions:
Unit can be run in cold rooms, incubators, and CO
2
environments from -10 to 60°C (14 to
140°F), maximum 80% relative humidity, non-condensing.
Applications:
Cell cultures, solubility studies, and extraction procedures.
