Aqueous Phase Syringe Filter

The aqueous phase syringe filter is mainly used for sample pre-filtration and clarification sterilization of particles, liquids, and gases, especially for the small amount of HPLC, GC samples.


One of the most prominent features of the aqueous phase syringe filter is that it is very suitable for the filtration of small samples in the laboratory. its adsorption of the sample is extremely low, which ensures the maximum sample recovery.

What's more, its housing is made of polypropylene and ultrasonically welded without any binders. Therefore, it would not contaminate the sample. The filter could be connected with a needle outlet, which allows to easily insert the sample solutions into the micro vial accurately. Plus, the syringe filter is equipped with the microporous membranes of different materials, which can be selected according to the requirements of the experiments.

The aqueous phase syringe filter is generally used for filtering neutral aqueous solutions, as well as clarification and filtration of the experimental samples and liquid chromatography filtration. For instance, it could be used for the clarification or sterilized for various solutions, including cell culture medium and microbial culture medium, reagents and additives, protein solution. However, it is not suitable for filtering organic solvents and strong acid and alkaline solutions.
