TheVWR? 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 systemin continuouslymonitors shaking speed andmaintains set-point，even under changing

loads. Displayed speed is accurate to 1% of setting.

Microprocessor control: The variable speedmicroprocessor control provides consistent uniformshaking

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 controlswith 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.

Ramping feature: Slowly increases speed to desired set-point to avoid splashing.

Audible alarm: In timedmode，alarmwill soundwhen the time reaches zero. Alarmhas optionalmute

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 CO2 environments from -10 to 60��C (14 to 140��F).
