Stainless Steel Vacuum Filtration Precautions

The laboratory vacuum filtration device is a commonly used instrument in the laboratory and can be used to separate particles and the like from liquid samples. Hawach stainless steel multi-filter vacuum filtration can carry out multiple (single, three, six) sample filtration at the same time, only one vacuum gas source can complete all operations, saving a lot of time, convenient and fast.

The multi-joint bracket is preferably 316L stainless steel that has been polished. It is resistant to most corrosive liquids and is used with glass or stainless steel diaphragm filters.

Features of Stainless Steel Vacuum Filtration

1. Each stand has a separate switch that can be operated separately.
2. The stable low center of gravity design prevents it from tipping over due to full solution loading.
3. The oxidized, beautiful aluminum handle distributes the ends of the base for added stability.

The diaphragm vacuum pump should pay attention to the following items in daily use:

1. A suitable vacuum pump should be used to match the vacuum filter bottle. If the vacuum pump with too much pressure may damage the filter membrane or the filter bottle during the suction filtration process, if the pressure is too small, the suction filtration effect cannot be achieved.

2. When filtering the sample each time, you should pay attention to the liquid level in the liquid collecting bottle, and pour out the remaining liquid in time before the liquid collecting bottle is full. Continued operation after the liquid collection bottle is full will cause the liquid to be sucked into the vacuum pump, which will easily cause damage to the vacuum pump.

3. When handling stainless steel filtration apparatus, wear appropriate personal protective equipment (PPE) such as gloves and safety glasses to protect against potential hazards. Exercise caution when handling sharp edges or points on the equipment to prevent injury.

4. Ensure that the pressure applied during filtration does not exceed the recommended limits for the stainless steel components. High-pressure conditions can lead to equipment failure, leaks, or potential hazards. Use a pressure regulator or control valve to maintain safe pressure levels.

5. Ensure that the vacuum source, such as a vacuum pump, is compatible with the stainless steel filtration apparatus. Verify the appropriate connections and pressure requirements between the filtration setup and the vacuum source to ensure efficient and safe operation.

6. Choose the appropriate filter membrane for the filtration process. Consider the compatibility of the filter membrane material with the chemicals, solvents, or samples being filtered. Select filters with the proper pore size to achieve the desired filtration efficiency.

7. Be aware of any potential chemical reactions or incompatibilities between the sample, solvent, or chemicals being filtered and the stainless steel filtration apparatus. Ensure that the materials used in the filtration system are resistant to corrosion or degradation under the filtration conditions.

8. Thoroughly clean and sterilize the stainless steel filtration apparatus before use to remove any contaminants or residues. After each use of the filter bottle, it should be promptly cleaned to avoid bacterial growth. If it is necessary, it should be autoclaved in time. Follow appropriate cleaning procedures, such as using suitable cleaning agents or autoclaving, to maintain a clean and sterile filtration system.

9. Properly dispose of the waste generated during the filtration process according to applicable regulations and guidelines. Follow appropriate waste disposal procedures to prevent environmental contamination and ensure compliance with safety standards.

10. Routinely inspect the stainless steel filtration apparatus for any signs of wear, damage, or leaks. Perform regular maintenance and replace any damaged or worn-out components to ensure reliable and safe filtration.
