LAUDA Hydro vaporization baths operate in a temperature range from 25 to 100 °C. The opening diameter of the water bath can be variably changed in approx. 20 mm steps by means of the nine-part ring set. These special baths for gentle vaporization work from columns, Erlenmeyer flasks or beakers are suitable for unattended continuous operation in the laboratory thanks to water level controllers and a water shortage protection. LAUDA Hydro vaporization water baths are available in five models, all equipped with a removable perforated cover with a multi-part ring set made of heat-resistant plastic.
