The universal water baths for the laboratory from 25 up to 95 °C

The LAUDA Aqualine water baths offer an affordable entry into laboratory thermostating. The equipment range for basic applications in the laboratory stands out for its simple operation with digital LED display and high reliability.

The devices have no circulating pumps and no fittings within the bath. Consequently, they are corrosion-resistant, easy to clean or disinfect, and provide maximum use of internal bath space. The heating elements housed under the bath vessel ensure homogenous temperature distribution without localised overheating.

Application examples

  • Preparation of medical samples for analysis
  • Temperature control of cytological samples
  • Pre-thermostating of samples for spectroscopic tests
  • Use in colleges and education

The Aqualine Advantages

Full use of the bath and easy cleaning of the inner chamber, thanks to the lack of installations in the bath vessel

Removable, transparent gable cover


Heating of the bath bottom across the entire base – excellent temperature homogeneity in the bath and optimum use of the internal space


Patented low-level protection, minimum fill level of only 2 cm – bath operation almost independent of the fill level


Recessed operating elements – dirt and drip-proof electronics


Luminous digital LED display – easy operation


Controller electronics integrated into the housing – smallest possible unit footprint


No heaters, sensors or other fittings in the bath vessel – easy-clean interior, no niches for hidden growth of germs, full use of the bath


Transparent polycarbonate gable covers removable without tools are a standard feature – easy and quick visual inspection of the samples in the bath


Optimised roof shape – easy cleaning, no height restrictions, prevents sample contamination from condensation

Aqualine Water Baths

The LAUDA Aqualine water baths are available in five different sizes. Depending on the size and the quantity of the samples, the user has the right bath depth or opening for his application at his disposal.

All the baths are made from moulded stainless steel, and do not have any fittings. As a result, the interior is used to its full advantage, and the number of samples per bath is maximised. Above all, the LAUDA Aqualine is designed for the requirements of biological, medical and biochemical laboratories. Thanks to the patented heating concept, the baths also achieve a high level of temperature homogeneity.
