CW3-05 Heating Bath Circulator (5L), 230V

CW3-05 Heating Bath Circulator (5L), 230V

The CW3-05 is a high-performance 5-liter heating bath circulator designed for exceptional temperature control and reliability in a laboratory setting. Operating on a 230V power supply, this unit offers precise thermal management for a wide variety of applications.

Unmatched Performance and Precision

The CW3-05 boasts an impressive temperature range from ambient +10°C up to 150°C, ensuring suitability for diverse heating tasks. At its core is a sophisticated microprocessor PID controller, which provides intelligent and responsive temperature management. For guaranteed accuracy, the unit features three-point temperature calibration, automatic tuning, and an automatic run function.

A key feature is its powerful, variable-speed pump, engineered for accurate, stable, and efficient temperature management. The pump offers five distinct speed settings: levels 1-3 are optimized for gentle internal circulation within the bath, while the more powerful levels 4-5 provide robust pressure for external circulation to other instruments. This dual-functionality ensures a strong, consistent pump pressure and flow rate across the entire operational temperature range.

User-Centric Convenience

Designed with the user in mind, the CW3-05 is simple to operate. A bright Vacuum Fluorescent Display (VFD), combined with a quick-adjustable dial knob, allows for effortless temperature setting with a fine 0.1°C resolution.

Productivity is enhanced with a dual wait on/off timer (1 min. to 99 hr. 59 min.) and a memory function that can store up to three frequently used temperature settings for instant recall.

The bath itself is constructed from high-quality, corrosion-resistant stainless steel. Its seamless, round-cornered design makes it exceptionally easy to clean and leak-proof, while a front-access drain valve simplifies fluid changes. For modern laboratory needs, the unit comes standard with an RS-232/USB interface for external computer control and data collection. It can also be monitored remotely via a mobile app using the LC Connected system (requires optional LC GreenBox). Sturdy side handles are integrated for safe and easy transport.

Integrated Safety Features

Safety is paramount. The CW3-05 features an isolated design where a baffle plate separates the agitator, heater, and sensor from the main bath area. This minimizes turbulence and protects both users and delicate samples from direct contact with heating elements.

A comprehensive safety protection system includes audible and visual alarms for critical conditions such as low fluid levels (preventing dry-running), over-temperature events, and over-current faults. Additionally, a keypad lock function can be activated to prevent accidental setting changes during operation, ensuring your experiments run without interruption.
