CW3-20P Heating Bath Circulator (20L)

CW3-20P Heating Bath Circulator (20L): Precision, Power, and Programmability

Meet the CW3-20P, a sophisticated 20-liter heating bath circulator engineered for exceptional temperature control in a variety of laboratory applications. This model is ideal for both internal immersion tasks and for regulating the temperature of external instruments. It combines a powerful, variable-speed pump with an intelligent programmable controller, ensuring your processes run with unparalleled accuracy and efficiency.

Key Features:

• Advanced Programmable Control:

  • Versatile Programming: Create and store up to 10 distinct programs, each with up to 10 individual steps. Set precise temperature ramps and dwell times (up to 99 hours and 59 minutes per step) for complex thermal profiles.
  • Effortless Sequencing: Easily link stored programs to run complex, multi-stage experiments and repeat cycles up to 99 times.
  • Pre-Heat Functionality: Program pre-heating and heating times to ensure your bath is at the precise temperature when your experiment begins.

• Exceptional Performance:

  • Wide Temperature Range: Operates reliably from ambient +5°C to 150°C (Amb. +9°F to 302°F).
  • Unwavering Stability: Microprocessor PID control, automatic tuning, and three-point temperature calibration deliver outstanding stability of ±0.05°C.
  • Powerful Pumping System: The variable-speed pump offers robust pressure and flow rates (up to 7.4 gal/min) across the entire temperature range. It features 5 adjustable steps: 3 for internal circulation to ensure bath uniformity and 2 higher-power steps for circulating fluid to external devices.

• User-Centric Design and Convenience:

  • Intuitive Touchscreen: A large, full-color LCD touchscreen with clear icons and logical menus simplifies operation and programming.
  • Durable and Cleanable Construction: The seamless, round-cornered bath is made of high-quality stainless steel for superior corrosion resistance and easy cleaning. A front-access drain valve allows for simple and safe fluid changes.
  • Enhanced Connectivity: An RS-232 interface (with a USB converter included) allows for external computer control and data logging. Digital I/O ports enable interlocking with other laboratory equipment for automated workflows.
  • Mobile Monitoring: Stay connected to your experiment from anywhere with the optional LC Connected mobile app (requires LC GreenBox), allowing you to monitor status and receive alerts on the go.
  • Easy Mobility: Built-in side handles and casters make it simple to transport and position the unit within your lab.

• Uncompromising Safety:

  • Isolated Component Design: A baffle plate isolates the agitator, heater, and sensors from the main working area. This minimizes fluid turbulence and protects both the user and delicate samples from direct contact.
  • Comprehensive Alarm System: The unit is equipped with a full suite of safety alarms, including alerts for low fluid levels (preventing dry-running), over-temperature conditions, and over-current faults.
  • Operational Security: A keypad lock function prevents accidental setting changes during critical operations, while the splash-proof keypad protects the electronics from minor spills.
