• Patented Opti-Flow forced ventilation system
• Patented Accu-Drive shaking system
• Calibration mode for temperature and speed

The Talboys Professional 3500 Incubating 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 the set-point, even under changing loads. When the unit is set to a speed above 100rpm, the speed accuracy is ± 1% of the set speed. When set under 100rpm, speed accuracy is ± 1rpm.
• Opti-Flow Forced Ventilation System: The exclusive patented Opti-Flow Forced Ventilation System uses twin induction fans and air deflectors to deliver exceptional temperature uniformity and stability.
• Microprocessor Control: The variable speed microprocessor control provides a consistent, uniform shaking action. The microprocessor will display the last set-point and will restart if power is interrupted.
• PID Temperature Controller: Maintains precise temperature control from ambient +5°C to 65°C. Easy-to-use controls allow users to adjust the temperature in 1°C increments. Meets ASTM E1292 specification for temperature uniformity.
• Triple Eccentric Drive: Permanently lubricated ball bearings and a 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 the operator to view all settings at once. The timer will display elapsed time or, when programmed to user user-defined limit, will shut off the unit when time reaches zero. The display will show the last used settings, even after the power has been turned off.
• Temperature Calibration Mode: Allows the user to calibrate the unit to an external temperature device.
• Speed Calibration Mode: Allows the user to automatically recalibrate the 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 the system detects an obstruction or overload of the tray.
• Overshoot Protection: Audible and visual signals will activate if the temperature deviates ±1°C from the set-point.
• Speed Ramping Feature: Slowly increases speed to the desired set-point to avoid splashing.
• Audible Alarm: In timed mode, the alarm will sound when the time reaches zero. The alarm has an 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 the temperature cools down.
• Spill-Resistant Design: Channels fluids away from internal components.
• Polycarbonate Lid: Permits viewing of samples without disturbing internal temperature. When the lid is opened, the automatic shut-off of the circuit will stop the shaker tray to protect the operator.
