Digital Thermostatic Stainless Steel Laboratory Circulating Water Bath
Digital Thermostatic Stainless Steel Laboratory Circulating Water Bath
Overview
Water bath is laboratory equipment made from a container filled with heated water. It is used to incubate samples in water at a constant temperature over a long period of time. Most water baths have a digital or an analogue interface to allow users to set a desired temperature, but some water baths have their temperature controlled by a current passing through a reader. Utilisations include warming of reagents, melting of substrates or incubation of cell cultures. It is also used to enable certain chemical reactions to occur at high temperature. Water bath is a preferred heat source for heating flammable chemicals instead of an open flame to prevent ignition.[1] Different types of water baths are used depending on application. For all water baths, it can be used up to 99.9 °C.[2][3] When temperature is above 100 °C, alternative methods such as oil bath, silicone bath or sand bath may be used.
Features
• Water-bath's maintain stable internal temperature with 20L heating capacity
• Temperature range up to +80°C
• LED display of the actual temperature.
• High temperature accuracywith overheating protection
• Precise temperature control with PID controller
• High temperature resistant and corrosion free lid made up of 304 stainlesssteel.
• The water bath has a dedicated internal magnetic circulation pump for uniform temperature distribution and also helps to prevent water leakage.
• The temperature homogeneity avoids any bumping phenomenon to occur during usage.
• Gable lid design prevents the steam droplets to drop into the sample. It can drop along on the side wall. It can ensure clean sample and temperature uniformity.

FAQ
Q1: What is the use of water bath in the laboratory?
A laboratory water bath is used to heat samples in the lab. Some applications include maintaining cell lines or heating flammable chemicals that might combust if exposed to open flame. A water bath generally consists of a heating unit, a stainless steel chamber that holds the water and samples, and a control interface.
Q2: What is the difference between water bath and incubator?
The major difference between these two pieces of equipment is the efficiency of the heat transfer to your samples. In a shaking water bath, samples are surrounding by water, an excellent conductor of heat. ... An incubator will heat up samples slowly and gradually.
Q3: Why is it important to maintain a constant volume of water in a water bath?
Water baths are used to incubate samples at a specific temperature for a long period of time. As time passes, water will evaporate and will cause the water bath to dry up. ... Hence it is important to maintain a constant volume of water in your water bath.
