1. Improve the airflow structure of the drying oven : The quality index of the "temperature uniformity" of the drying oven mainly depends on the structure of the airflow. The drying box usually adopts a single air duct structure to organize the airflow, and the airflow mainly comes from the centrifugal fan system. In this structure, the design of the casing of the centrifuge and the design of the wind deflector are the key to determining the index. Therefore, we first redesigned the volute in strict accordance with the Archimedes spiral principle. The airflow of the air outlet of the volute can be evenly blown through the heater to ensure uniform air supply. In addition, the air outlet and air outlet of the air deflector have also been correspondingly improved to increase the air volume of the air inlet as much as possible, while increasing the air pressure and wind speed of the air outlet. The airflow can be evenly circulated in the working room. Second, determine th

The  Laminar flow cabinet （ ultra-clean workbench ）  is widely used in the electronics, precision machinery industry that mainly controls dust and agriculture, forestry, and medical and health services that mainly control dust, bacteria, and viruses. The installation of the ultra-clean workbench is very important. The installation steps are as follows: 1. The choice of the installation position of the ultra-clean workbench will directly affect the use effect and service life. Therefore, when installing the ultra-clean workbench, it must be installed in a plant with good hygienic conditions. It is best to lay a plastic floor or a water mill floor to facilitate cleaning and dust removal, and pay attention to the sealing of doors and windows to avoid the influence of external dust particles on the interior. Extend service life and ideal purification effect. 2. Open the product packaging, check whether the physical items are consistent with the items listed in the packing list, the

The dust on the surface or inside of the drying cabinet is mostly tiny dust particles with a small amount of static electricity, which often floats in the air and moves with the airflow, and it will adhere to the object when it encounters it, and it will be almost impenetrable. Dust attached to the model specimen will affect its color, dust on moving parts will increase wear, dust on electrical appliances, severe cases will cause a short circuit, leakage, valuable dust on precision instruments, serious cases will make the instrument scrapped. drying oven There are many ways to remove dust in the drying oven , which should be determined by the condition of the dust surface and the degree of dust adhesion. In the dry air, if there is less dust or the dust has not been dampened and become a patch, you can use a dry cloth to wipe, towel brush, soft brush and other methods to remove the dust on the general instrument; Blowing and dusting off the ear-washing ball pump can also be us

There are many laboratory instruments and equipment, and large instruments and equipment are valuable. Be aware that these devices are small, but they are more practical and powerful. When the glassware is dried in a small drying oven , first remove the water in the container as much as possible to prevent the water from dripping and causing the oven to be damaged.

The airflow pattern of the biological safety cabinet is quite special. Let me explain in detail below. The fan sucks the ambient air into the air intake grille on the operation table in front of the work area of ​​the biological safety cabinet, to avoid polluting the surface of the work table and user samples, and the entering gas is not mixed with the clean gas in the cavity of the work area. Ambient air enters through the air inlet in front of the work area to avoid contamination by the surface of the work area and the sample. The intake air flow does not mix with the clean gas in the working area of ​​the safety cabinet, passes through the channel, and flows to the air pressure chamber (fan chamber) on the top of the safety cabinet. About 30% of the gas in the air pressure chamber passes through the filter and is discharged into the room. The remaining 70% of the gas passes through the sink air filter and enters the work area, forming a clean vertical air flow to the work surfac

The drying oven has a galvanized liner and a stainless steel liner. Prices vary, so do you know what is galvanized and what is stainless steel? Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metals, alloys or other materials for aesthetic and rust prevention. The main method used is hot-dip galvanizing. Stainless steel is the abbreviation of stainless acid-resistant steel. It is resistant to weak corrosive media such as air, steam, water or stainless steel. According to your needs, choose the inner tank of different materials.

Many customers encounter a problem after purchasing a vacuum drying oven . Should the vacuum drying oven be evacuated first or heated first? The following Kenton instrument will introduce the correct operation method of the vacuum drying oven: vacuum oven vacuum oven The experimental product is put into the vacuum oven  to evacuate to remove the gas components that can be removed from the material of the workpiece. If the workpiece is heated first, the gas will expand when heated. Due to the tightness of the vacuum oven, the huge pressure generated by the expanding gas may cause the tempered glass of the observation window to burst. This is a potential danger. You can avoid this danger by following the procedure of vacuuming and heating first. If you operate according to the program of heating up and then vacuuming, when the heated air is pumped out by the vacuum pump, the heat will be carried to the vacuum pump, which will cause the temperature of the vacuum pump to rise
