- PTFE: Being inert to various corrosive solvents and strong acid&alkali.
- Regenerated Cellulose: High resistant to chemicals and biological samples.
- Glass Microfiber: Suitable for solutions with high suspended solid content or high viscosity.
To keep good filtration effect and high filtration efficiency, it is best not to reuse the syringe filter.
Some syringe filters for HPLC are sterile and only for disposable use, otherwise they can cause sample contamination.
- Fill 90% volume of syringe with sample and the remaining 10% is air.
- Find out the appropriate syringe filter for filtering this sample.
- Twist inlet end of filter cautiously into syringe and the outlet is connect with HPLC.
- Slowly manually push the syringe plunger, squeeze the sample flowing for filtration.
- Material: Select the right material through the natures of sample, such as acid and alkaline solution is best choose regeneration cellulose syringe filter, high viscosity solution needs to use glass fiber syringe filter and so on, specifically can refer to question 2.
|Typical Process Volume||Suitable Syringe Filter Diameter (mm)|
|< 1 ml||3|
- Size: Choosing the suitable diameter of syringe filter according to the volume of samples. Refer to the table below:
Note: Table data is for reference only, and the details can be selected according to the actual situation.
Yes, syringe filter for HPLC has period of validity.
The best effective time for syringe filter is three years, and the production batch number and expiration period are very clearly printed on the package for reference. In order to ensure the optimal filtering performance of syringe filters, please use it within the shelf life.
Filson has complete stock about standard size syringe filter for HPLC.
- Common apertures: 0.2μm, 0.45μm, 1.2μm, 3μm, 5μm, 10μm, etc.
- Common diameters: 3mm, 13mm, 25mm, 30mm, 50mm, etc.
As the syringe filter captures impurities during filtration continually, the pressure on filter increases and syringe plunger becomes difficult to push. When the pressure is too high, you’d better replace syringe filter for HPLC to ensure excellent filtration effect and avoid rupture of filtration membrane.
