Questions regarding nitrogen protection filtration
Thread Content
Is there any device in the laboratory that can be used for filtering under nitrogen protection? Note: Currently, it is still at the pilot scale, with a maximum volume of 5 liters and a minimum of 0.5 liters. I would appreciate some advice from the experts here. :time:
What equipment do you plan to use for filtering? There are now many devices for nitrogen-preserved filtration, such as centrifuges and filter presses ； Nitrogen-sealed filtration can be achieved in all cases
Could you provide a detailed explanation of the nitrogen sealing device used in centrifugal filtration?
Thank you all. I know there are many devices on large vehicles that can achieve this, but I’m not sure about those used in small-scale tests. Could anyone provide information on the equipment available for use in such tests? :time:
Simple nitrogen sealing protection device: bubble type
Upstairs, could you provide a schematic diagram?:time:
Protective devices for laboratories can be made. Make a suction filter funnel with a lid, load material intermittently, install a nitrogen probe at the top of the lid, and connect a suction flask below the funnel. During suction filtration, nitrogen can be introduced first to remove air and effect displacement. Then add the materials and adjust the vacuum level
