The Complete Introduction To PTFE Syringe Filters

A filter uses to remove particles from a liquid. A syringe is a tool that uses to pass the liquid through it by applying little force. So, a syringe filter is a small filter that removes particles from a liquid. Syringe filters are disposable items. During the testing, the PTFE Syringe Filter is placed on the end of a syringe, and the liquid draws through the filter. The PTFE filter removes the particles, if any, from the liquid. These filters use for a variety of vivid liquids like acids, bases, and organic solvents. Simsii is a credible and reputed syringe filter company, that shares information about the complete introduction to PTFE syringe filters.  

The PTFE Syringe Filter

The PTFE syringe filter is a tool, used for filtering liquids as well as gases. A porous membrane of polytetrafluoroethylene (PTFE) fits in it. The membrane covers by a housing made of stainless steel or plastic. Syringe filters also utilize for filter samples that will inject into animals or humans. Porous material allows passages of pre-defined molecule size but not vaster than that. Pore sizes of the membrane depend on the liquid you will use to filter. You can find different levels of filtration. As the level of the syringe filter will raise, its value will also.

 

If the size of the chromatography membrane is 0.4-0.45 micrometers, it will survive long. We know that the PTFE filter is a hydrophobic membrane. It means PTFE Syringe Filter repels water and is unsuitable for aqueous solution. PSF filters of 25 mm size have been specially designed and tested to mitigate the strict regulatory requirements of automation systems. These syringe filters are ideal because of their broad chemical compatibility and high pH resistance.

Generally, after the expiration of pre-sterilized syringe filters, they may return to the manufacturers. One notable point is that the expiration date applies only to the sterility of the PES Syringe Filter and not to its performance. The filter membranes install between the vacuum pump and the receiving flask to restrict accidental overflows. When it becomes hot, its housing strength reduces.

 

Sterlitech syringe filters have the male luer slip and female luer lock connection if their diameter is 30 mm or less. Pore sizes of 5 microns or higher are available for these filters. These syringe filters sterilize by using a control mechanism of Gamma Radiation exposure.

 

Conclusion

For a particulate-free environment, the PTFE Syringe Filter is a reliable option for devices. Its polymer membrane’s thin sheet, called porous, allows only air and the pre-defined size particles to pass through. The qualities of PTFE filters make them an excellent choice for medical equipment and air filters, which help in a clean and green environment.
