Construction – Sterile laboratory syringe filters made of PES

Sterile laboratory syringe filters made of PES are small devices that are used in medicine and laboratories to remove microorganisms, particulates, as well as proteins and other contaminants from solutions or suspensions. They consist of three main parts:

  • filter body
  • filter membrane
  • syringe tips

The filter body is usually made of plastic and contains an inner layer of filter membrane that is responsible for retaining contaminants. The tip of the syringe is a component that allows the filter to be easily attached to the syringe, as well as to be drawn and injected solution or suspension through the filter.

Varied variants

Googlab syringe filters are available in a variety of sizes and membranes for sterile and non-sterile laboratory applications. The most commonly used type of membrane for sterile syringe filters is PES, which has a specific pore size that determines the size of the particles that are retained during filtration. PES membrane has the characteristics of high flow and low protein adsorption, which can meet a wide range of applications such as buffer, protein, medium, other additives. Filtration of aqueous solutions, buffers and media, high protein>recovery 98.5

Syringe filters are used in many fields such as biotechnology, chemistry, medicine, pharmacy, and research laboratories. They are used to purify samples prior to analysis, to prepare samples for microbiological testing, and to prepare purified solutions for medical purposes.
