Bubble point pressure is not a criterion for measuring the quality of a microporous filter membrane. It is mainly used to determine the low pressure required for liquid to begin passing through the pores on the filter membrane. The bubble point pressure of 0.45um microporous filter membrane is usually between 1-2 bar.

The quality of microporous filter membrane should comprehensively consider the following factors:

1. Filtration efficiency: The quality of a microporous filter membrane can be evaluated by its filtration efficiency. Filtration efficiency refers to the ability of a filter membrane to filter particles or microorganisms of a specific size. Higher filtration efficiency means that the filter membrane can filter target substances well and provide pure products.

2. Flow performance: A good 0.45um microporous filter membrane should have good flow performance, that is, maintaining filtration efficiency At the same time, it can provide sufficient traffic. Higher flow performance increases filtration speed and operating efficiency.

3. Physical strength: The microporous filter membrane should have sufficient physical strength and pressure resistance to ensure that it will not break or deform during the filtration process.

4. Chemical compatibility: Microporous filter membranes should be compatible with the chemical composition of the liquid being filtered to avoid chemical reactions or dissolution problems.

5. Reliability and consistency: A good microporous filter membrane should have stable performance and be able to maintain consistent filtration effects in mass production.

Therefore, when evaluating the quality of microporous filter membranes, the above factors need to be considered comprehensively. Bubble point pressure is only one of the indicators. 0.45um microporous filter membrane is mainly used to determine the pressure required to start filtration, but it cannot comprehensively measure the performance of the filter membrane. It is recommended that when selecting a microporous filter membrane, refer to the technical specifications and performance parameters provided by the manufacturer, and conduct a comprehensive evaluation based on specific application requirements.
