A Brief Introduction to Syringe Filter

This is a useful weapon for experimental analysts to filter micro-samples quickly and effectively, such as sample pre-filtration, clarification, and filtration of particles, liquids, and gases sterilizing, etc.

The structure of Hawach syringe filter

The structure of Hawach syringe filter consists of housing and membrane. As the name suggests, it is the combination of syringe and filter and connects to the front end of the syringe. The syringe is an external manifestation—housing, essentially a filter—membrane. Its main function is to separate the mixed two phases. The housing and membrane can be made of many different materials. Membrane, in the industry, the most common materials are Nylon, PVDF, PTFE, MCE, CA, Glass Fiber, PP, PES.

The choice of analysts syringe filters

To start from the perspective of the most user demand– experimental analysts have a natural obsession with fast and accurate. Keep filtering or aseptic filtration with hundreds of cleaning the filter and replacing membranes will destroy all–it must be wise to choose syringe filter. It is essential for sample preparation, determination, even environmental detection, fuel analysis, and other directions.

Precautions for syringe filters use

Avoid the introduction of other impurities into the filtrate during the filtration process. Select the appropriate filter membrane to handle samples of different properties.

Syringe filters are widely used in laboratories. The users do not need to change membranes and clean filters, which can save complex and time-consuming preparations. It is very convenient and easy to operate. They are mainly used in sample pre-filtration, clarification, degerming of particles, liquids & gases and so on. It is the preferred method for filtering small samples of HPLC and GC.

Hawach Scientific is specializing in filtration products for more than 15 years. Our syringe filters are made of extractable free medical grade virgin polypropylene housings, with standard inlet (Female Luer Lock) and outlet ( Male Luer) connections unless others stated. Options include different diameters, membrane types, sterile filters in blister packs for critical applications. The options of membrane types have Nylon, PTFE, PP, Active Carbon in both sterile and Non-sterile, and with or without pre-filter.
