What Happens if a PVDF Membrane Is Stored at 4°C Without Drying or Blocking After Transfer
Placing a polyvinylidene fluoride (PVDF) membrane into a 4°C refrigerator immediately after membrane transfer, without prior drying or blocking, may result in several potential issues:
1. Residual Moisture
If moisture remains on the membrane, the low temperature may cause condensation, potentially affecting the membrane’s physical structure and overall performance.
2. Structural Alterations
Storing a wet PVDF membrane can lead to changes in its structural properties, which may compromise its effectiveness in subsequent applications, such as filtration or separation.
3. Microbial Contamination
Although low temperatures inhibit the growth of most microorganisms, prolonged storage may allow cold-tolerant microbes to proliferate, particularly if residual nutrients are present on the membrane.
To minimize these risks, it is recommended to thoroughly dry the PVDF membrane before refrigeration. This precaution helps preserve the membrane’s structural integrity and functional performance.
