-
Pharmaceutical quality control: Conducting stability studies, solubility tests, controlled sample processing during temperature tests
-
Food analysis: Temperature conditioning of butyrometers for fat determination in milk or other food samples, for example
Suitable media: Mainly distilled or deionised water and suitable laboratory liquids that are stable within the defined temperature range.
FAQs on practical use
Calibration - How does temperature adjustment work?
The devices offer user-defined calibration (two-point) for internal and external probes. The settings can be made in the setup menu via the display; detailed instructions can be found in the operating manual. This guarantees consistently precise temperature control even with different media. Which media may be used? Water and non-corrosive, temperature-stable laboratory liquids are recommended. Do not use flammable or aggressive liquids to avoid damage and safety risks.
How is the device cleaned?
The device must be emptied before cleaning. It can then be cleaned with a mild cleaning agent and a soft cloth. Avoid using harsh or abrasive agents to protect the stainless steel and seals.
What special features increase safety during operation?
In addition to overheating protection and low level warning, the control panel lock prevents unauthorised access. Visual and acoustic alarm signals in the event of malfunctions ensure a quick response to protect valuable samples.
Conclusion
With its exceptionally precise temperature control, comprehensive safety features and flexible range of models, this water bath enables reliable process optimisation in the laboratory. Its intuitive operation, excellent stability in accordance with DIN 12876-3 and versatile interfaces make it one of the most sought-after temperature control devices in research, development and quality assurance.
