Heating mantles and water baths are laboratory equipment used in different areas and each has its own distinctive features and applications, which we will explain below.
Heating mantles are devices used to maintain a stable temperature determined for a specific process. Their design makes the transfer effective thanks to the uniform distribution of temperature throughout the area in contact with the container and the materials it is made of. They are the best choice for the user due to their fast heating and thermal response.
This laboratory equipment is made of stainless steel and CR steel and is also provided with an electrostatic paint coating. It has a high thermal resistance fiberglass coated heating element. In addition, it has rods for holding glass parts with a height of 50 cm.
What are the characteristics of the heating blanket?
The heating mantle is an equipment used for various processes, among which we can mention, soxhlet extraction, kjeldahl, boiling and distillation among many others. They can be found in different volumes, ranging from 100 ml to 3000 ml. They are equipped with analog control or also come with PID digital control.
How do thermal blankets work?
These devices operate on the principle of heat transfer by conduction. The temperature rise of the fluid is efficiently achieved through the metal wall of the vessel. The materials are one of its main characteristics, since the interior is made of silicone insulating elements and resins that favor heat flow (thermal conductivity) towards the container and not towards the outside of the blanket. This prevents heat loss to the surrounding environment and at the same time makes handling safer. It also has a regulation and control system to optimize the efficiency of the process and prolong the life of the electrical resistance.
What is a water bath?
The water bath is an equipment used in the laboratory for serological tests and incubation, agglutination, inactivation, biomedical, pharmaceutical and even industrial procedures. They are generally used with water, but can also be used with oil. The temperature ranges in which they are normally used are between room temperature and 60 °C. Water baths are manufactured with chambers whose capacity can be selected from 2 to 30 liters.
What is the principle of operation of a water bath?
Water baths consist of a tank made of stainless steel, which has a set of electrical resistances mounted on the bottom of it, through which heat is transferred to a medium such as water or oil, which is maintained at a preselected temperature through a control device – thermocouple, thermostat, thermistor or similar – that allows selecting the temperature required for the different types of analysis or tests. It has an external body where the aforementioned controls are located, which is made of steel and is generally coated with electrostatic paint of high adherence and resistance to the environmental conditions of a laboratory.
