Syringe Filters for HPLC and sample preparation

Pore Sizes and Pore Volumes. The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are usually for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3.5 µm) 0.45 µm

The filtration device is useful for removing particulates from samples. Each pre-asseled unit has a filter merane on one end of the plunger and a pre-attached cap/septum on the other. Positive pressure forces the filtrate through the merane as you press the chaer and plunger together. Air escapes through the vent hole until evaporation seal engages, providing an air-tight seal.

What is a syringe filter? A syringe filter (or wheel filter) is a single-use, merane-based device used for the removal of particulate impurities from small (≤ 100 mL) liquid samples (Figure 1).Selected based upon the desired end appliion, disposable syringe filters are commonly used in labs for fast and efficient filtering, material purifiion, or even sterilization.

The MF test is easier to perform than the MPN test because it requires fewer test tubes and less handling. Usually about 100 ml of water is passed through a merane filter (pore size 0.45 µm). This merane is then placed on a thin, absorbent pad saturated with differential or selective medium (Figure 17.2).For example, if total coliform organisms are sought, a modified Endo medium is used.
