When choosing syringe filters, there are a number of factors which you need to keep in mind. This article provides the factors.
If you need to separate the ion and the polar molecules, you need to put in mind a number of factors to make sure you buy filter syringe which will fulfill all the requirements. It will play a great role in making sure that some of the particles and other micro-organisms have been removed during the process of preparing the samples. A syringe filter will be used during a number of industrial applications. Such applications include the development of pharmaceutical drugs, clinical, and other industrial applications.
It can be difficult to determine the type of syringe filter which you need to use. Here are tips on selecting the best syringe filter.
Connection Types
When carrying out ion chromatography, there are two syringe filters which are used and they are the female lock inlet and male lock outlet. The design ensures there is a secure connection for all the applications.
The Material of the Membrane
The type of solution which will flow through the syringe filter will have a great impact on the material of the membrane. Make sure you take this into consideration when you are deciding the type of material which you need to use.
There are some materials which are high protein binding while there are others which are low protein binding. There are also some which will repel water and this means that water will not be flowing through them.
There are around 15 different membrane materials used in making the syringe filters and you need to take your time and select the one which will meet your application requirements.
The Diameter of the Syringe
The diameter of the syringe filter should be able to handle the sample size. The more you will be pushing through the filter, the more the size of the syringe you will need.
The diameter will affect the cost and volume which can be held by the syringe. It is advisable to choose the minimum diameter of the syringe since it will keep your costs down. A large diameter will hold up a bigger space and it can waste part of your sample.
Sterility
Sterility will depend on your ion chromatography application. You would use sterile filtration when you are using biological solutions. In most cases, the sterile filter syringes are wrapped and they contain an expiry date.
On the other side, a non-sterile application would be more appropriate if you are removing particles.
Size of the Pores
It is influenced by the size of the suspended particles in your solution. You need to know the size of the particulate so that you will know the size of the syringe filters which you need to choose.
There are some syringe filters which have a prefilter which increases the life of the filter by allowing a free flow of the fluid.
Selecting a syringe filter will require you to take a number of factors into account. Before you buy filter syringe, remember the above factors.
