Backlit LCD Display
The OPX-244 is equipped with a backlit LCD display on applicable configurations, allowing users to clearly monitor both set values and current operating values.
The intuitive display helps simplify the adjustment and monitoring of stirring speed, temperature and timing parameters during laboratory operation.
DC Brushless Motor
The instrument uses a DC brushless motor designed to provide smooth and stable stirring performance.
Compared with conventional brushed motors, the brushless design eliminates brush-related wear and helps provide:
- Low-noise operation
- Reduced maintenance requirements
- Smooth speed control
- Stable continuous operation
- Reliable laboratory performance
The stepless encoder-based speed adjustment allows the operator to precisely adjust stirring speed according to the sample and application.
Advanced Stirring Function
The OPX-244 provides multiple operating modes designed to maintain consistent stirring performance under changing external conditions.
The instrument supports forward and reverse rotation, allowing the direction of stirring to be changed according to the mixing requirement.
The programmable operation function can be used for applications requiring controlled stirring sequences and switching between operating conditions.
Forward & Reverse Stirring
The positive and inversion function allows the stirring direction to alternate between forward and reverse operation.
This feature can help improve mixing and homogenization for samples that require enhanced agitation rather than continuous rotation in a single direction.
The instrument can also support program editing and temperature switching on applicable configurations.
High-Temperature Magnetic Stirring
The OPX-244 uses high-temperature-resistant magnetic steel designed to provide sufficient magnetic attraction and torque between the drive system and the magnetic stir bar.
The strong magnetic coupling helps maintain effective stirring, even when working with laboratory solutions that require higher stirring loads.
Heating Function
Heating is available on the applicable OPX-244 configurations. The heating system can provide temperature control up to 300°C, depending on the selected model.
The heating and stirring functions can be operated together, making the instrument suitable for applications requiring simultaneous mixing and controlled heating.
Temperature Control
Applicable configurations provide a temperature control range of room temperature (RT) to 300°C.
The system can be configured with PT-1000 temperature sensing, providing external temperature measurement and control for applications where precise sample-temperature monitoring is required.
The supplied specification indicates temperature control accuracy of:
- Tray: ±3°C
- Solution: ±5°C
Working Plate
Depending on the selected configuration, the OPX-244 series can be supplied with different working-plate materials, including:
- Cast Aluminium + Ceramic
- Tempered Glass
The working plate provides a stable surface for laboratory vessels during heating and stirring operations.
Timer & Programmable Operation
Selected configurations provide a timer range of:
1 minute to 99 hours 59 minutes
The timer function is useful for applications where stirring or heating needs to operate for a predefined period.
