Key Features

Intelligent Program Control Unlock sophisticated temperature profiling with our intuitive programming system. Create, store, and link complex thermal cycles with ease.

• 10 Customizable Programs: Design up to 10 multi-step programs for precise temperature ramp-up, ramp-down, and dwell control.
• Advanced Step Control: Each program can contain up to 10 individual steps, with each step programmable for up to 99 hours and 59 minutes.
• Program Linking: Seamlessly link stored programs to create extended and complex experimental sequences.
• Cyclic Operation: Repeat programs up to 99 times for long-term stability tests and automated processes.
• Programmable Start: Set pre-heating or pre-cooling times to ensure the bath is at the desired temperature exactly when your program begins.

High-Fidelity Performance Experience exceptional temperature stability and uniformity for both internal and external circulation needs.

• Wide Temperature Range: Operates from -25°C to 150°C, suitable for sub-zero cooling, general incubation, and high-temperature applications.
• Microprocessor PID Control: Delivers rapid response and minimal overshoot, maintaining precise temperature stability.
• Automated Calibration & Tuning: Features three-point temperature calibration, automatic tuning, and auto-run capabilities for optimal performance right out of the box.
• Adjustable Five-Speed Pump: The powerful pump provides whisper-quiet operation. Use lower speeds (1-3) for gentle internal circulation to minimize turbulence, and higher speeds (4-5) to provide robust flow for external applications like cooling viscometers or rotary evaporators.
• Built-in Cooling Coil: Enhances cooling efficiency and allows for rapid temperature reduction.

Unmatched Convenience & Connectivity Designed for the modern lab, the RW3-2025P prioritizes ease of use, maintenance, and data management.

• Intuitive Touchscreen Controller: A large, full-color LCD touchscreen with clear icons and logical menus simplifies operation and program setup.
• Dual Timers: Program two independent wait on/off timers (from 1 minute to 99 hours, 59 minutes) for automated operation.
• Digital I/O Port: Integrate the circulator with external devices for automated, interlocked process control.
• Modern Connectivity: A standard RS-232 and USB interface allows for external computer control and seamless data collection.
• Remote Monitoring: Connect the optional LC GreenBox to monitor and control your circulator from anywhere via the LC Connected mobile app.
• Easy Maintenance: A high-quality stainless steel bath with rounded corners prevents corrosion and simplifies cleaning. The unit features an easy-access drain valve, a quick-release front grill for condenser cleaning, and a detachable condenser air filter.
• Eco-Friendly Refrigerant: Utilizes CFC-free refrigerants (R-507, R-404A) with a double service valve to prevent leaks and protect the environment.
• Mobility: Equipped with built-in casters and side handles for effortless transportation and installation.

Comprehensive Safety System Multiple layers of protection ensure the safety of the user, the sample, and the instrument.

• Isolated Component Design: A baffle plate isolates the agitator, heater, and sensors, protecting samples from direct contact and minimizing fluid turbulence.
• Visual Temperature Indicator: A color-changing indicator provides an at-a-glance status of the reservoir's temperature.
• Automatic Safety Alarms: A complete protection system alerts users with audible and visual alarms for low fluid levels (preventing dry-running), over-temperature conditions, and over-current faults.
• Keypad Lock: Prevents accidental changes to settings during critical operations.
• Splash-Proof Design: The keypad is designed to resist accidental spills, ensuring long-term durability.
