SW23 Stirring Water Bath – Precision, reliability and ease of use for the most demanding applications
The Julabo SW23 is a high-quality stirring water bath for laboratory applications that require thermal precision, optimum homogeneity and controlled stirring. Whether for enzyme or tissue studies, corrosion tests, temperature tests on food and beverages, or routine operations, the SW23 efficiently meets the needs of researchers.
Its operating temperature range extends from +20 °C to +99.9 °C, covering a wide range of applications. Equipped with PID1 control, it offers exceptional temperature stability of ±0.02 °C, made possible by its integrated circulation pump, ensuring even heat distribution throughout the tank.
The SW23 also features a user-friendly interface: the waterproof, ergonomic keypad allows easy adjustment of temperature, timer and stirring frequency settings. The multi-value LED display ensures clear data readout, even from a distance, with a display resolution of 0.1 °C.
The tank capacity, ranging from 8 to 20 litres, combined with an adjustable stirring frequency between 20 and 200 rpm, makes the device particularly adaptable. The removable stirring insert allows easy installation of samples outside the bath and prevents direct contact with the fluid.
The SW23 incorporates several safety features: an optical and acoustic alarm system, an automatic shut-off function in case of excessive or low temperature, and protection against dry operation. Classified as NFL (non-flammable fluid), it complies with DIN 12876-1 and has an IP21 protection rating.
For documentation and automation purposes, the SW23 has an RS232 port for connection to a PC for data transfer or use with control software such as EasyTemp.
The bath's structure is designed for durability and hygiene: high-quality stainless steel and sloped edges prevent spillage when the lid is open. The unit can also be equipped with a lift-up lid (Makrolon or stainless steel) for added convenience.
The SW23 is therefore much more than just a water bath: it is a complete, reliable and high-performance laboratory partner that adapts to complex protocols while simplifying daily operations.
