Advanced Motorless Magnetic Technology
The OPX-245 uses an advanced magnetic coil system instead of a conventional motor-driven mechanism.
The magnetic drive produces the required magnetic field for rotating the stirrer bar inside the vessel. Because the stirring drive has no conventional moving mechanical drive components, the system is designed for wear-free operation and reduced maintenance requirements.
This makes the OPX-245 particularly suitable for laboratories requiring compact, quiet and reliable stirring equipment.
Automatic 30-Second Pulse Function
The OPX-245 incorporates an automatic pulse/reverse function that changes the stirring direction every 30 seconds.
This periodic reversal helps improve mixing by changing the direction of liquid movement rather than continuously rotating the stirrer bar in one direction.
Benefits of Pulse Mode
- Improved mixing performance
- Better sample homogenization
- Reduced dead zones during mixing
- Useful for solutions requiring thorough agitation
- Automatic forward/reverse operation
Digital LED Display
The digital LED display provides a clear and convenient way to monitor the operating parameters.
Depending on the selected configuration, the display provides information related to:
- Stirring speed
- Timer setting
- Operating status
The clear digital interface makes the instrument easy to monitor during laboratory operation.
Speed Control
The OPX-245 provides a wide speed range of:
15–1500 rpm
The speed can be adjusted in 50 rpm increments, allowing the user to select an appropriate stirring speed according to the sample viscosity and mixing requirements.
Stainless-Steel Working Plate
The instrument incorporates a stainless-steel working plate designed for laboratory use.
The working surface provides a stable platform for laboratory vessels and is suitable for routine handling of liquid samples.
The specified working/setting diameter is 105 mm.
IP65 Protection
The OPX-245 is designed with an IP65 protection class, providing resistance against dust and water jets under the applicable IP testing conditions.
This makes the unit particularly useful in laboratory environments where accidental liquid spills or splashes may occur.
Slim & Compact Design
The OPX-245 features a slim, flat-surface design that occupies minimal laboratory bench space.
The compact construction makes it suitable for laboratories where multiple instruments need to be placed on the same working surface.
Timer & Infinite Mode
The instrument provides:
- 99-minute timer
- Infinite operating mode
The timer allows users to define a specific stirring period, while infinite mode enables continuous operation until manually stopped.
Last-Run Memory
The OPX-245 incorporates a last-run memory function, allowing the instrument to retain the previous operating settings.
This can be useful when repeating routine laboratory mixing procedures.
Stirrer Bar
The OPX-245 is supplied with PTFE-coated magnetic stirrer bars according to the selected configuration.
Standard Stirrer Bar
25 × 8 mm PTFE-coated stirrer bar
PTFE coating provides a chemically resistant surface suitable for a wide range of laboratory liquids.
