Syringe filters are an important tool in the analysis of biological samples, as they help to remove unwanted substances and fine particles of rated pore size. These filters play a vital role in ensuring that the extracted sample is pure and free from contaminants, which can significantly affect the accuracy and reliability of downstream analytical procedures. Adding a needle filtration step prior to chromatographic injection helps ensure more consistent and reliable results, and helps protect the instrument and extend column lifetime.

Our company offers a wide range of economical syringe filters in various sizes and membrane types, catering to different application needs. Whether you require a filter for small sample volumes or larger sample volumes, we have the right solution for you. Our filters are designed with precision and care, ensuring optimal performance. One popular type of syringe filter is the hydrophilic PVDF syinge filter which consists of HPLC certified PVDF filter membrane and medical grade polypropylene housing. These disc shape syringe filters are a good choice for general biological filtration applications for many researchers and scientists.

When filtering aqueous samples using a hydrophilic PVDF syringe filter, there is no need to pre-wet the filter membrane with alcohol. This simple step can greatly simplify the laboratory analysis process and minimize the risk of contamination, which can have a significant impact on the accuracy and reliability of the results. PVDF syringe filters are also characterized by low protein binding capabilities, making them ideal for applications requiring high protein recovery such as in biochemistry research or clinical diagnostics. However, they should not be used for filtration of DMF, DMSO, MEK, ACETONE, most corrosive solutions or strong bases due to their limited compatibility with these substances.

Specifications Available

Sterile single packaging and non-sterile bulk packaging in barrel are available.

Applications

Hydrophilic PVDF Syringe Filters can retain fine particles to the specific pore size and remove interfering substances, and are an essential component in many laboratory workflows, ensuring efficient and accurate analysis while minimizing potential contamination or interference.

• HPLC/ GC-MS small volume sample preparation and clarification
