Thermes

Laboratory water baths provide controlled heating for samples, reagents, and containers immersed in a temperature-controlled water reservoir. Common applications include sample incubation, reagent warming, thawing, and temperature-sensitive laboratory preparation.

A water bath transfers heat through heated water and can accommodate different compatible vessels. A dry bath uses heated metal blocks with openings for specific tube sizes. Dry baths avoid a water reservoir and are often preferred for routine microtube or test tube heating. The right choice depends on your sample format and temperature requirements.

Choose a shaking water bath when your application requires controlled heating and sample agitation at the same time. These systems can be useful for certain incubation, extraction, mixing, and sample preparation procedures. Confirm the motion type, speed range, vessel capacity, and temperature range before ordering.

Choose a water bath based on the number and size of vessels, working water depth, available chamber space, and required operating temperature. Check internal chamber dimensions as well as litre capacity, particularly when heating flasks, bottles, or several samples at once.

A bead bath uses compatible thermal beads rather than water as the heating medium. This can reduce water-related maintenance and provide an alternative for certain vessel shapes and heating workflows. Some models, such as the BeadBath Duo, support both water and bead operation. Always check the manufacturer's requirements for the heating medium and application.

Not always. Some dry bath heaters require heating blocks to be purchased separately. For example, Cambridge's Traditional Dry Baths and IsoBlock listings identify blocks as separately sold items. Confirm the required tube size, block configuration, and included accessories before ordering.

A general-purpose laboratory water bath is designed for controlled heating, not validated sterilization. Do not assume a bath can replace an autoclave or other validated sterilization equipment. Select equipment according to the temperature, process, and safety requirements of your procedure.

Yes. Cambridge Environmental can help compare water baths, dry bath heaters, shaking baths, bead baths, and immersion circulators based on capacity, temperature range, sample format, accessories, and Canadian purchasing requirements.
