The selection and maintenance of ultra-low temperature chiller
Today, a customer came to inquire about our need for a small laboratory water chiller. The specific working condition is to reduce the materials in the 20L stainless steel reactor from normal temperature to minus 30 ℃ in more than one hour. This product is too simple for us. The LT-50 series chiller can easily meet all the operating conditions. For model selection, please remember the basic formula: tank volume (or material weight) * material specific heat * temperature difference/second. The...
View detailsWhere will the reactor be used? How about the reactor temperature control system?
Generally, non professionals should be confused about the reactor. The reactor is composed of reactor body, reactor cover, jacket, agitator, transmission device, shaft seal device, support, etc. It is generally understood as a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the functions of heating and mixing, hydrolysis, neutralization, distillation, evaporation, crystallization, storage, hydrogenation, alkylation, po...

The mixing tank with jacket and insulation layer is a three-layer insulation mixing tank with heating function, which has the functions of heating, insulation, mixing, etc. It is widely used in dairy, chemical, food, beverage, pharmaceutical, pharmaceutical and other industries. The refrigeration heating temperature control integrated machine is matched with the liquid preparation tank for temperature control, the fully closed temperature control system, the multi-function alarm system and th...
View detailsUse and maintenance of laboratory/bioengineering temperature control system
1. Read the equipment manual carefully before use, get familiar with the operation process and key instructions, and operate in strict accordance with the conditions specified in the manual. 2. When moving the laboratory/bioengineering temperature control system, avoid striking the equipment shell, vibrating and damaging or polluting the keypad (function key display). 3. Before use, make sure to regularly check (at least once every two years) whether the equipment is in normal working condit...

How to choose the optimal chiller solution?
Choosing a water chiller is like finding a "target" for an enterprise's production equipment. It must not only be "like-minded", but also "be well-matched". The one that suits you is the best. If the choice is not good, either the cooling effect is not ideal, or energy is wasted, and other problems will appear. First consider the actual situation of your own business, starting from six points: 1. The relationship between temperature difference and flow rateHow much material, how long does it...
View detailsTemperature Control Soultion for Wafer Cleaning Solution in Semiconductor Industry
With the rapid development of semiconductor technology, the requirements for wafers are getting higher and higher, making clean wafer surfaces more and more important for the manufacturing of semiconductor devices. In the wafer manufacturing process, cleaning is required after each step of the process. At present, the wafer cleaning and etching methods often need to set up a large number of spraying structures to spray different chemical solutions to the wafer surface for cleaning and etching...
View detailsHow to control the temperature of solvent recovery by distillation?
1. If the product quality is not affected by the presence of air at a higher temperature, it can be recovered at normal pressure first, and when the temperature exceeds the normal pressure boiling point of the desolvent by 10 degrees, when the solvent cannot be evaporated, change the receiving bottle, and then reduce Pressure, the degree of vacuum rises slowly from -0.01mpa to the maximum according to the flow rate. Continue to keep for 0.5 hours until no liquid flows out. 2. If the product ...

How to control the emulsification temperature of the emulsifier?
A good cream product is not only reflected in the quality of raw materials, but also has a great influence on the emulsification process during production, such as the texture and stability of the product, and the temperature control during production will affect the cream product. Generally speaking, the emulsification temperature is determined by factors such as the melting point of the high melting point substance contained in the two phases, the type of emulsifier, the solubility of the o...

Why is it dangerous to use an enamel reactor?
The enamel layer of the enamel reaction kettle is easy to burst when it is cold and hot. Because the enamel layer is sintered on the surface of the enamel reaction kettle, and the enamel layer will melt when it exceeds 200 degrees Celsius, so the temperature of the material in the kettle is not allowed to exceed 200 degrees Celsius, so the enamel kettle has a temperature resistance limit of 200 degrees Celsius, and the temperature resistance rapidly becomes cold. Shock <110℃, thermal shoc...
