Constant Temperature Metal Bath VS Constant Temperature Water Bath
Water bath is a common laboratory thermostat, the liquid medium of the water bath is water, the boiling point temperature is usually 100 degrees Celsius. When boiling water in a standard environment, no matter how big the fire is and how long it takes, as long as there is still water boiling, its temperature must be 100 degrees. In this way, heating with a water bath can control a constant temperature.
The water bath is mainly used in universities and colleges, research enterprises and institutions of laboratory and laboratory, digital display electronic constant temperature water bath widely bit for drying, concentration, distillation, impregnation of chemical reagents, impregnation of drugs and biological products, can also be used for water bath constant temperature heating and other temperature test, is biological, genetic, virus, aquatic, environmental protection, medicine, health, biochemical laboratory, analysis room education and research tools. For a variety of chemical samples, biological products for distillation, drying, concentration and warm stains, is the laboratory experimental equipment.
Constant temperature water bath placed horizontally inside the stainless steel tubular heater, the interior of the water bath is placed with a perforated aluminum shelf. The upper lid is equipped with a combination of different caliber collars, which can be adapted to different caliber flasks. There is a water discharge pipe on the left side of the water bath, and an electrical box on the right side of the constant temperature water bath, with temperature control instrument and power switch on the front panel of the electrical box. There are electric heaters and sensors inside the electrical box. The temperature control system uses electronic components, sensitive temperature control, reliable performance and easy to use. Its working principle: Cu50 sensor converts the temperature of water in the water bath into resistance value, and after amplification and comparison by integrated amplifier, the control signal is output, which effectively controls the average heating power of the electric heating tube and keeps the water in the water bath at a constant temperature.
Common point
Both are temperature-controlled, can be heated or cooled, and put your desired test tube or container inside for constant temperature cultivation.
Differences
1. Different in the mode of heat conduction. Constant temperature water bath is water or ethanol as the medium, through the form of electric heating, so that the medium to achieve the ideal constant temperature of constant temperature of a thermostat; constant temperature metal bath is the use of semiconductor materials, through the form of electric heating, to achieve constant temperature effect.
2. Temperature range is different. Metal bath heating fast and accurate precision, high controllability, the temperature fluctuation coefficient of the water bath is larger than the metal bath.
3. The scope of application is different. The metal bath is suitable for small micro-sample constant temperature experiments, the application range of the water bath compared to the metal bath to a wider range.
4. The constant temperature metal bath can meet the constant temperature experiment of some rapid heating or cooling, and is the instrument of choice for some sample preservation, preservation and reaction of various enzymes, deformation treatment of nucleic acid and protein, PCR reaction, pre-denaturation of electrophoresis and serum coagulation experiment.
