Notice of Tomb sweeping Day Holiday in 2024 Tomb sweeping Day is an ancient festival of the Chinese nation. It is not only a solemn festival of tomb sweeping and ancestor worship, but also a happy festival for people to get close to nature, travel in spring and enjoy the fun of spring.In accordance with the provisions of national statutory holidays, and in combination with the actual situation of the company, we will first make the following decisions on the Tomb Sweeping Day holiday
1. Fully enclosed compressor is used for refrigeration, which is characterized by fast cooling, low noise, excellent performance and reliable quality.2. There is a heating system at the bottom, which uses heating to balance refrigeration to avoid frequent startup of the compressor and increase the service life of the compressor.Low temperature constant temperature reaction bath 3. Digital display temperature control, PID control added
High temperature oil bath is a commonly used heating equipment in the laboratory. It has the characteristics of fast heating speed, controllable temperature and uniform heating, and is widely used in chemistry, medicine, food and other fields.However, due to its work in high temperature and high pressure environment, if used improperly, it may pose a serious threat to personnel and equipment.Therefore, comply with
Diaphragm vacuum pump is a device that uses the reciprocating motion of diaphragm to generate vacuum.It drives the diaphragm mechanically or electrically to make it reciprocate in the pump chamber, thus compressing and stretching the fixed volume of air to form a vacuum (negative pressure).This pump is usually simple in design, easy to operate, and can provide relatively clean
The multi-purpose vacuum pump for circulating water is a kind of equipment that uses fluid jet to generate negative pressure for air extraction. It is widely used in many industries.The following are some specifications for use: 1. Installation and preparation: place the multipurpose vacuum pump flat on the workbench and ensure its stability.When using, it is necessary to open the upper cover of the water tank and inject clean
The circulating water multipurpose vacuum pump is a common vacuum equipment, which is widely used in scientific research, industrial production, laboratory and other fields.In order to ensure the safe operation of the equipment and extend its service life, correct operation and effective maintenance are essential.Today, I will introduce the installation of the circulating water multipurpose vacuum pump
Jacketed glass reaction kettle is a common chemical equipment, which is composed of several key parts. The composition structure mainly includes kettle body, kettle cover, jacket, agitator, transmission device, shaft seal device and support.Each part has its own specific function: 1. Kettle body: it is the space for materials to react, usually made of round
The explosion of the double glass reaction kettle is very dangerous, which poses a threat to people's lives and property in the production test. It is a top priority to grasp the causes of the explosion of the double glass reaction kettle and effectively curb the occurrence of this phenomenon.First, the violent reaction of substances will lead to reactor explosion. Some chemical reactions are exothermic reactions.
1、 Routine maintenance and repair of explosion-proof rotary evaporator 1. Keep the equipment clean: after each use, clean the exterior and interior of the rotary evaporator in time to avoid residues adhering to the equipment and affecting the normal operation of the equipment.2. Check the working state of the equipment: before use, check the power cord and plug of the equipment
The explosion-proof high and low temperature circulator is a kind of circulating constant temperature equipment with explosion-proof function and a wide range of controllable temperature. It is usually used in the laboratory to carry out high and low temperature environment simulation experiments.Its functions are as follows: 1. Temperature regulation: it can accurately adjust the temperature in a wide range of temperatures, so that it can simulate a variety of heights
