How to choose laser chiller?
The term laser is an acronym for light amplification by stimulated radiation. When the electrons in the atoms of optical materials (such as glass, crystal or gas) absorb the energy of the current, a laser is generated. The increased energy excites electrons and moves their orbits from low energy to high energy to produce electromagnetic radiation. In normal light, light waves move in different wavelengths and directions. Each wavelength has a different color, with peaks and valleys. The ligh...

What should we pay attention to when storing the refrigerant of the chiller? What are the acceptance
Refrigerant is an essential substance to make the chiller have refrigeration effect, which has great potential safety hazards in the use process. Refrigerant, also called refrigerant, refrigerant carrier and snow seed, is used in different equipment in different ways, and the composition of the refrigerant is different. Refrigerant in industrial products is explosive and has potential explosion hazard, so special attention shall be paid to storage. In addition, it is recommended not to fill ...
View detailsThe 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...

What are the decarboxylation reaction conditions and process temperature control?
The decarboxylation of aromatic acids is easier than that of fatty acids. For example, benzoic acid can be decarboxylated by adding a little copper powder as a catalyst in quinoline solution and heating. When a strong electron-withdrawing group is attached to the α-C of the carboxylic acid, heating can make it decarboxylate more smoothly. For example: when the ortho-diaromatic organic acid is heated, it is easy to remove a carboxyl group, but when the temperature is low, an acid anhydride w...

Necessity of temperature control in fractional distillation of distillation
The pharmaceutical and chemical industry involves many chemical reactions, and with the continuous development of the pharmaceutical and chemical industry, there is a great demand for such instruments. The traditional open cooling and heating constant temperature bath is not efficient, and the temperature range of the fully enclosed high and low temperature all-in-one machine can reach -120 degrees to 200 degrees, which can meet the needs of many enterprises. The high and low temperature all...

Harm of dust to thermal oil temperature control system of reactor
Dust in daily work will also have a certain impact on the circuit board work of the thermal oil temperature control system of the reactor. Dust is an unevenly dispersed system composed of particles suspended in the air. It mainly comes from industrial emissions, combustion Soot, soil dust, etc. Let me explain what the dangers are. 1. Dust will float with the air. When it floats above the circuit board, a certain electric field will be generated when the circuit board is working. These elect...
