Syringe Filter
A Syringe Filter (pronunciation: sɪˈrɪndʒ ˈfɪltər) is a wheel-shaped filter. It has a plastic body with a membrane used for the removal of particles from a sample. The sample is passed through the membrane using a syringe.
Etymology
The term "Syringe Filter" is derived from its use with a syringe and its function as a filter. The word "syringe" comes from the Greek word "syrinx", which means "tube", and the word "filter" comes from the Medieval Latin "filtrum", meaning "felt", a material that was used for straining liquids.
Usage
Syringe filters are commonly used in laboratory settings for the sterilization of small to medium volumes of liquid, such as culture media, protein, and DNA solutions. They are also used in the removal of microorganisms and particles to ensure a clean sample.
Types
There are different types of syringe filters which are classified based on the type of membrane material used. These include Nylon, Polypropylene, Polyvinylidene fluoride (PVDF), and Polytetrafluoroethylene (PTFE) syringe filters.
