Construction – Sterile laboratory syringe filters made of PES

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

• filter body
• filtration membrane
• syringe tip

The filter body is usually made of plastic and contains an inner layer of filter membrane that is responsible for retaining contaminants. The syringe tip is an element that allows you to easily attach the filter to the syringe, as well as to draw and inject the solution or suspension through the filter.

Varied variants

Googlab syringe filters are available in a variety of sizes and with different 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 particles that are retained during filtration. PES membrane is characterized by high flow rate and low protein adsorption, which can meet wide applications such as buffer, protein, medium, other additives.

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