How To Choose Syringe Filters In The Lab?

Consisting of a filter medium and housing or holder that constrains and supports the syringe filter media in the sample’s path, filters are good tools when you need removing particulates from samples in the lab.

We have three basic types of laboratory filters.

Membrane filters size rating of the membrane is determined the size of the pores. Centrifugal filters are suitable for separating such as protein or nucleic acid desalting and concentration. These devices drive the liquid through the filter through centrifugal force. And syringe filters which consist of a filter element and housing assembly are used when a sample must be filtered before entering a syringe.

To select the best filter for your process, ask yourself the following questions:

1. What are you going to filter?
2. What is the size and nature of the particles or molecules to be removed?
3. Chemical composition of your sample.
4. Viscosity.
5. Suitable temperature.

More to be concerned upon your applications:
1. To achieve the separation, what pore size or nominal molecular weight rating is required?
2. Do you need a sterilizing filtration?
3. How quickly do you need to filter?
4. Pressure-driven or vacuum-driven filtration?

Now, your knowledge is improved to obtain accurate separation of your sample, mobile phase or other liquid.
