Syringe filters also known as wheel filters can be defined as single-use filter cartridges situated at the end of a syringe. Syringe filters have been known to possess luer lock fittings to ensure that they are securely fitted to the syringe. They are available in an array of useful membrane types to cater for the various applications of different consumers. Individuals should be thoroughly knowledgeable of the application of filter membranes before selecting any type and consequently proceeding to purchase it. Having the appropriate syringe filter for the required solutions is necessary for the optimum device performance.
PTFE Syringe Filters are also known as Halogenated Solvent Safe. PTFE is an abbreviation for Polytetrafluoroethylene membranes which are resistant to almost all bases, acids and solvents. The PTFE has decreased extractables and excellent thermal stability. It is hydrophobic and needs pre-wetting before it can be used together with aqueous solvents. It is popularly used with aromatics, alcohols, bases, aggressive solvents and strong acids. It is not recommended for use with aqueous samples before it is sufficiently pre-wetted. This is because it results in a high back pressure.When used for sterilization with syringe filters, it is done for fifteen minutes at a temperature of 125˚C. Applications of PTFE membranes are filtration of aggressive organic solutions or even solutions that are highly basic. They are also used in transducer protectors.SpecificationsThis type of filter has a number of attractive and very useful specifications that consumers stand to enjoy as follows:If you buy PTFE syringe filter you can be guaranteed of optimum usability and performance. It has pore sizes such as 0.1 m, 0.22 m, 0.45 m and even 1.2m. The filter diameter is 13mm. If you buy a PTFE syringe filter, a pack contains 100 pieces and is packaged in polythene boxes that are of the low dust type. The polythene box packaging decreases dust levels in clean-room areas. The luer lock attachments are designed to be used in conjunction with luer-lock syringes that are rubber free solvent safe. The luer lock system is specifically of the female type that conveniently fits into the male outlet. The filter housing is made of polypropylene. Hydrophobic PTFE membranes are excellent for chlorinated solvents such as dichlorobenzene, chloroform and chloro-benzene. Organic semiconductors use these solvents repeatedly. It has been established that the 13mm diameter PTFE syringe filter offers the optimum combination of filtering capacity with low solution loss. The 0.45 m offers the ideal general purpose filtering without the risk of clogging. The 0.45 m PTFE syringe filter provides an ideal general purpose syringe filter that facilitates safe filtering of all organic materials close or at the materials’ solubility limit. Whenever one is filtering some samples, it is essential to use the appropriate membrane for the particular application. PTFE Syringe Filters are versatile in use and are resilient to harsh everyday chemicals. These are some of the reasons why this type of syringe filter is very popular in the market and will continue to receive overwhelming attention from consumers of a number of sectors. They are simply the most ideal and affordable at the same time.
