WiseBath – waterbath WB-6/WB-11/WB-22/WSB-18/..

wisebath_wb-11  Each laboratory device Wisd waterbath is clearly usable in biotechnology, medical and clinic, also in applications of the pharmaceutical and petrochemical industry. Also in experimental education in schools and universities our Wisd waterbaths can be found.

Each Wisd waterbath is equiped with a security power circuit, which independent from other factors on faults, prevents an over range temperature. So you can use our devices smoothly unattended with adjusted timer-function (with filled in medias which has a low boiling point and temperature settings which can overboil the medium, an unattended usage needs to be prevented always).

If you need high temperatures for your probes, we can offer you our oil baths of the category Wisd WiseBath WHB. with this laboratory devices you are able to temper up to 250°C.

Instead if you need a shaking water bath which shakes your probes automatically while tempering, the waterbaths of the category Wisd WiseBath WSB are the right water baths for you. With the continuous shaking of your sample, a extremely uniform tempering of your sample is ensured. Partial overheating of your sample is surely prevented.

More precise and uniform heating with circulator

For maximum uniformity while tempering, our waterbaths of the product category Wisd WiseBath WCB in opposite to the models of the category Wisd WiseBath WB are equipped with an integrated circulator. The circulation improved the temperature uniformity dramatically.

Application

Water baths are used for indirect and uniform heating and tempering. always you need a vessel of any form for your substances, to dip in the waterbath and heat up your probe. In opposite to a hotplate the thermal energy in a waterbath will be directed from all sides in the probe vessel and not only from the bottom. With the open design of the water bath you are able to automatically oder manually move, rotate or shake the vessel, to warm up you probe uniformly. You can put the vessel also in the waterbath, and close it with a flat or dome lid to induce the thermal energy more efficient in you probe. Please recognize that condensate can drop from the inner side of the lid inside your probe. How the product category is named, water is the medium for transferring the thermal energy from the heater to you probe vessel. Determined by the system, this works only controlled and uniform beneath a temperature under 100°C. Clearly you should always avoid boiling up the water.
