Incubating 3500 Orbital Shaker offers exceptional temperature
uniformity and is designed for a variety of shaking and incubating applications, such as cell
cultures.
Operating Features:
Accu-Drive Shaking System:
The exclusive patented Accu-Drive Shaking System delivers
exceptional speed control, accuracy, and durability. The 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 speed microprocessor control provides consistent
uniform shaking action. Microprocessor will display last set-point and will restart if power is
interrupted.
Opti-Flow Forced Ventilation System:
This patented system uses twin induction fans and
air deflectors to deliver exceptional temperature uniformity and stability.
PID temperature controller:
Maintains precise temperature control from ambient +5°C to
65°C. Easy-to-use controls allow users to adjust temperature in 1°C increments. Meets
ASTM E1292 specification for temperature uniformity.
Triple 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
temperature, speed and time allow operator to view all 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.
Temperature calibration mode:
Allows user to calibrate unit to an external temperature
device.
Speed calibration mode:
Allows user to automatically recalibrate speed display.
RS-232 interface:
Provides two-way communication for data logging and unit control.
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.
Overshoot protection:
Audible and visual signals will activate if temperature deviates ±1°C
from set-point.
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.
Caution hot indicator:
Symbol illuminates when the temperature of the air in the chamber
reaches 40°C and remains lit until temperature cools down.
Spill-resistant design:
Channels fluids away from internal components.
