Frequently asked questions
What is the difference between a water bath (bain-marie) and a thermostatic bath?
The conventional water bath transmits temperature statically through water or oil by natural convection, suitable for general heating processes. By contrast, a circulating thermostatic bath incorporates active mechanical recirculation pumps (such as the Agibat-20 model) that force fluid movement, guaranteeing stability of up to ±0.1 °C and eliminating any thermal gradient within the chamber.
What is an ultrasonic bath used for in the laboratory?
Ultrasonic baths fulfil a triple function in the modern laboratory: microscopic, non-abrasive cleaning of complex instruments (micropipettes, optical components or sieves); rapid degassing of liquids and organic solvents intended for high-performance liquid chromatography (HPLC) analysis; and controlled acceleration of chemical reactions or cell disruption processes.
What heat-transfer fluids are recommended depending on the bath's working temperature?
For routine experimental work operating between ambient temperature and 99.9 °C, distilled water is used as the thermal medium. However, if the assay requires temperatures up to 200 °C continuously, the equipment must be configured as an oil bath using specialised synthetic silicone fluids of high density, which provide high boiling points and avoid the risks derived from water boiling.
How do I choose the right bath capacity?
Capacity depends on the volume and number of samples to be processed simultaneously. JP Selecta baths range from 2 L (individual use) to 200 L (multi-sample processing). Allow a 30 % additional margin over the real sample volume. If you need technical advice, consult with our experts.
