Know Some Surprising Facts About Syringe Filters

By Monisha Thomas
Syringe Filters look like wheel shaped filters. They have a plastic body having a membrane, which is utilized for purifying the contaminants. Their chief use is to remove the microbes and harmful particles from gases, or liquids. In addition to this, they possess a syringe that is associated with filter membrane. There is a fabulous plethora of pour sizes, in which these filters are available in the market. A Nylon filter is also found with numerous hydrophobic and hydrophilic membrane materials.
These syringe filters are utilized in an array of...
applications including environmental sample analysis, HPLC sample preparation, bio fuel analysis, routine QC analysis, protection precipitation, food analysis, and many more. Apart from this, various industries use this filters involving environmental and general laboratory, pharmaceutical, food and beverage, and many others. As far as HPLC is concerned, these filters are utilized for removing the particles from the sample prior to its entering the column.
Consequently, the precision of results as well as the life of the column substantially increase. The membrane used by these filters may be of Nylon mixed cellulose, PES, polypropylene, or PTFE. The nature of the sample finalizes which filter should be used. Mixed cellulose of nylon syringe filters (both are hydrophilic membranes) are utilized to purify aqueous samples. Aside from this, sensitive biological samples are dealt by mixed cellulose ester membrane. They are chiefly made of cellulose acetate, and cellulose nitrate.
Furthermore, hydrophobic membranes (like Poly tetra fluoroethylene) are utilized in order to deal with non-polar solvents. It is a resistant polymer by nature, and useful for highly aggressive as well as corrosive solvents. Since they contain an ample amount of high stability, these polymers are used to purify bases and acids, as well. The moisture present in air vents can also be thwarted by using PTFE membrane. Polyethersulfone or polyyinylidene difluoride membranes (both are low protein binding filters) are used to purify protein samples.
Their nature is hydrophilic. PES membranes are preferred for inorganic samples that are utilized in ion chromatography. They are able to recover most of the samples. Besides this, Syringe Filters have been found to be useful in numerous applications ranging from milk commerce to commercial industries. Propylene membranes are useful with organic solvents and aqueous, as they are hydrophobic in nature. However, you should consider the diameter as well as pour size of filter while you choose these membranes for staying healthy.
Axiva lab is one of the growing company that is manufacturing and supplying various types of nylon syringe filters such as nylon syringe filters, membrane filters, ptfe filters that is useful in numerous applications.
