Scientific research water bath Hydro

thermostaticcoolingheating

Overview
The LAUDA Hydro shaking water baths provide precise temperature control and controlled sample agitation for laboratory applications. Models H 20 S and H 20 SW perform linear, oscillating shaking; model H 20 SOW provides an orbital (circular) motion. Built-in speed controller enables load-independent, infinitely variable shaking with soft start. H 20 SW and H 20 SOW include a cooling coil as standard. Connecting to mains water or an external circulation chiller extends the lower temperature limit to approx. 10 °C. Rear drain tap facilitates emptying.

Benefits and added value

• Digital temperature setting and display via LED
• Load-independent, continuously variable shaking with soft start
• Electronic monitoring of controller functions and two independent under- and overtemperature protection devices
• Bath body, cover frame with condensation channel, shaking basket and heater in stainless steel

Working range
Standard minimum working temperature: 25 °C; maximum up to 99.9 °C depending on model. With connection to water supply or an external chiller the lower limit can be extended to about 10 °C. Typical temperature stability: 0.1 ± K.

Key performance values

• Min. working temperature (standard): 25 °C
• Min. working temperature (with external cooling): ~10 °C
• Max. working temperature: 99.9 °C
• Temperature stability: 0.1 ± K
• Heater power (example): 1.5 kW
