What Is The Unique Filtering Principle Of Laboratory Vacuum Filtration Device?
Vacuum filtration devices are mainly used for high-performance liquid chromatography mobile phase filtration, particulate matter analysis, and microbial contamination detection. They are standing equipment in chemical laboratories. It is made of high-quality borate glass or 316L sanitary stainless steel, which can filter various aqueous solutions, organics, and corrosive liquids during analysis, and can be hot-pressed and disinfected at 121℃.
Lab vacuum filtration device
The laboratory vacuum filtration device adopts an integrated structure design, which collects filter bottles, suction filter funnels, vacuum pumps and other accessories required for laboratory filtration in one machine, to facilitate the overall movement and save laboratory space. It is sturdy and durable, more convenient to wipe and clean when there is filtrate dripping during filtration.
Within about 10 seconds after the vacuum pump is started, the vacuum negative pressure tank can be drawn into a negative pressure cavity of not less than 91.2KPa (68.4 mmHg), and then the solenoid valve 3 or 5 is connected under the action of the pressure difference, to make the liquid in the filter pan quickly passes through the filter paper to dehydrate. It can be used in chemical analysis, instrument analysis, sanitary inspection, biological products, and petroleum, environmental monitoring and other aspects of liquid filtration to monitor and remove particles and bacteria in the liquid.
The structure is simple, compact, and the vacuum system works reliably, with a high degree of vacuum. In order to prevent liquid in the vacuum negative pressure tank from entering the vacuum pump, upper and lower contacts are set in the device. When the liquid reaches a predetermined height, the vacuum pump automatically stops, open the air release solenoid valve and start it by itself after the liquid is discharged.
