How do I choose the right pore size for my lab application?

For sterile filtration of tissue culture media, biological fluids, and sensitive HPLC samples, a 0.22 micron pore size is recommended to remove bacteria and fine particulates. A 0.45 micron pore size is generally used for faster clarification of less critical samples. These Biomed Scientific filters offer the precise 0.22 micron size for critical applications.

Which membrane material is best for filtering organic solvents?

PTFE (Polytetrafluoroethylene) membranes, like those in these Biomed Scientific syringe filters, offer excellent chemical resistance and are ideal for filtering aggressive organic solvents and harsh chemicals. They are also suitable for aqueous solutions, providing versatility for various laboratory filtration needs.

Are these syringe filters sterile and safe for biological applications?

Yes, these Biomed Scientific syringe filters are certified sterile, non-pyrogenic, and biologically safe. They are individually packaged and gamma irradiated to maintain sterility until use, making them suitable for critical applications like tissue culture media preparation and filtering biological fluids.

How do I ensure the sterility of the filters until use?

Each filter is individually packaged in a sterile pouch and gamma irradiated. This ensures that the filter remains sterile until the moment you open the package, maintaining the integrity of your samples and experiments. An individual expiry date is provided for each filter.

What is the difference between 0.22 micron and 0.45 micron pore sizes?

A 0.22 micron pore size is considered sterile and effectively removes bacteria and fine particles, essential for cell culture media and sensitive analytical samples. A 0.45 micron pore size is typically used for general clarification and faster filtration of samples where complete bacterial removal is not the primary concern.

Can I reuse these syringe filters?

No, these Biomed Scientific syringe filters are designed for single-use only. Reusing them can compromise sterility, lead to filter damage, and introduce contaminants into your samples. Always use a fresh, sterile filter for each application.

Why choose this product

Biomed Scientific: Precision Filtration

Biomed Scientific focuses on delivering high-performance filtration solutions for research and laboratory environments. These sterile PTFE syringe filters are designed for critical applications where purity and sterility are paramount. Unlike generic filters, each unit undergoes rigorous integrity testing and gamma irradiation. The PTFE membrane provides superior chemical resistance and low protein binding, ensuring sample integrity for sensitive analyses. Imported directly from authorized US retailers and partners, these filters offer a trusted, high-quality option for your laboratory needs.

Who Should Use These Filters?

Ideal for researchers in molecular biology, cell culture, pharmaceutical compounding, and analytical chemistry who require sterile filtration of aqueous or organic solvent samples. Suitable for preparing tissue culture media, clarifying biological fluids, and filtering protein solutions. Those needing reliable, sterile, and chemically resistant filtration for HPLC or GC sample preparation will find these filters effective. If you require a filter for general water purification or non-sterile applications, less specialized options may suffice.

How to use

Select a sterile syringe and attach the Biomed Scientific sterile PTFE syringe filter to the Luer-lock inlet. Ensure a secure connection to prevent leaks during filtration. — Prepare Syringe
Draw the sample solution (e.g., cell culture media, biological fluid) into the syringe. Avoid overfilling the syringe to prevent sample loss during filtration. — Load Sample
Gently and steadily depress the syringe plunger to force the sample through the 0.22 micron PTFE membrane. Filter the entire sample volume. Use sterile technique throughout. — Filter Sample
Once filtration is complete, carefully detach the syringe filter and dispose of it properly in a biohazard waste container. These filters are for single-use only. — Dispose
