Witeg WCB-22H – High-precision digital immersion circulator for 22 L water baths
The WCB-22H from Witeg is a digital immersion circulator designed to meet the needs of laboratories, research centres and industrial facilities requiring precise temperature control. Its generous 22-litre capacity allows it to handle large volumes of liquid while maintaining uniform regulation thanks to an integrated pump with a flow rate of 5 l/min. With a heating power of 2 kW and a reliable PT100 sensor, this device quickly reaches the desired temperature while maintaining exceptional stability with an accuracy of ± 0.1 °C. The operating range extends from ambient temperature + 5 °C to 100 °C, covering a wide range of applications.
Ease of use, clear display and complete safety
The WCB-22H's ergonomic design features an easy-to-read backlit LCD display, even in poorly lit environments, and a jog shuttle for quick and precise adjustments. The device offers the option of storing temperature and time settings, which optimises repetitive procedures. The built-in timer, programmable up to 99 hours and 59 minutes, offers operating modes with delayed or continuous start, suitable for a variety of experimental protocols. Safety is at the heart of its design: it features parameter locking to prevent accidental changes, protection against overheating and overloading, a low water level warning system and automatic shut-off to protect samples and the unit. Sensor error detection and audible alarms ensure constant monitoring.
Multiple applications and proven reliability
Thanks to its robust design and precise control, the WCB-22H is suitable for use in many sectors: biological analysis, analytical chemistry, quality control, the pharmaceutical industry, food processing and environmental research. It is ideal for applications such as incubation, dissolution, stability testing or sample preparation requiring constant temperatures.
Its compact dimensions (130 × 165 × 320 mm) make it easy to integrate into a laboratory bench, while its gross weight of 10 kg ensures stability and easy transport. Its reliability, combined with low maintenance, makes it a safe investment for any organisation seeking to guarantee precision and repeatability in its thermal procedures.
