PTFE Syringe Filter FAQ Guide

How Do You Use PTFE Syringe Filter?

How Do You Use PTFE Syringe Filter

There are several steps for you to use PTFE syringe filter:

  • Firstly, load sample into PTFE syringe filter.
  • Secondly, fix the syringe filter by twisting. You should twist connectors(commonly luer lock) properly, not too loose or too tight.
  • Thirdly, keep syringe filter vertical in order to wet PTFE membrane. If possible, discard the first 0.25ml of sample to avoid pollution.
  • Next, push syringe filter and let sample flow through filter.
  • Finally, change filter and repeat theses steps again.
Are PTFE Syringe Filters Autoclavable?

Are PTFE Syringe Filters Autoclavable

Yes.

Most PTFE syringe filter is non-sterile, and it can be autoclaved by dry heat at 121℃ for 15 – 30 minutes. And PTFE syringe filter is ideally used in HPLC samples, air and gas venting and degassing, aggressive chemicals filtration and so on.

What is The Difference Between Pore Size and Porosity?

What is The Difference Between Pore Size and Porosity

Pore size refers to the diameter of pore in filter, and it determines the particles size which can pass through filter. For example, the pore size of Filson PTFE syringe filter ranges from 0.1 to 10 micron. That means this filter can capture most particles larger than 0.1 micron.

Besides, nominal pore size means the main or common pore size of one filter, while absolute pore size is the largest pore size of one filter.

Porosity refers to the percent of the surface area occupied by pores. Generally speaking, the typical porosity of filter is less than 80%.

What Is Bubble Point and How to Determine It?

What Is Bubble Point and How to Determine It

Bubble point in PTFE syringe filter is the minimum pressure to push bubble through the biggest pore. Bubble point takes part in pore size vary inversely. So, if pore size is small, bubble point is big and vice versa.

In most syringe filter, bubble point can be customized by specifying the pore size. More importantly, bubble point specification is used to control filter quality during production process. And customers can also use bubble point to test the filter quality.

Do PTFE Syringe Filter Remove Bacteria?

5. Yes. The common pore size of bacteria ranges from 0.5 to 5 micron, and PTFE syringe filter has wider micron rating between 0.1 and 10 micron. Therefore, almost all bacteria can be removed through PTFE syringe filter.
