Sterile needle filters may encounter some common faults during use. The following are some possible faults and troubleshooting methods:

Low filtration efficiency: This may be caused by clogging of the filter membrane or slow flow rate of the filtrate. You can replace the filter membrane or adjust the filtrate flow rate to solve this problem.

Poor filtrate quality: may be caused by improper selection of filter membrane pore size or membrane rupture. It is necessary to check the pore size and integrity of the filter membrane, and select a suitable filter membrane to improve the quality of the filtrate.

Filter leakage: It may be caused by damage to the filter casing or failure of the sealing ring. It is necessary to inspect the filter housing and sealing ring, and replace damaged parts in a timely manner to solve the problem.

Filter blockage: It may be caused by the presence of particles or sediment in the filtrate. Measures such as cleaning the filter or replacing the filter membrane can be taken to eliminate blockages.

Abnormal filter pressure: It may be caused by factors such as too fast filtrate flow rate or clogged filter membrane. It is necessary to check the filtrate flow rate and filter membrane aperture, and adjust the flow rate or replace the filter membrane to solve the problem.

In addition to the common faults mentioned above, sterile needle filters may also have other issues, such as shell deformation, aging of sealing rings, etc. During use, it is recommended to regularly inspect and maintain the filter to ensure its normal operation and improve its service life.
