Cobetter is a company that specializes in filtration and separation technology, including syringe filters. Syringe filters are used in various laboratory and research applications to filter and clarify liquids.
They consist of a plastic housing with a membrane filter that is designed to remove particles and contaminants from a sample while allowing the desired liquid to pass through.
Cobetter offers a range of syringe filters with different membrane materials, pore sizes, and sizes to suit various filtration needs.
Membrane Materials: Cobetter syringe filters are available with different membrane materials such as nylon, PTFE (polytetrafluoroethylene), PVDF (polyvinylidene fluoride), and more. The choice of membrane material depends on the compatibility with the sample and the type of particles you need to filter.
Pore Sizes: Syringe filters come with various pore size options to accommodate different particle sizes. Smaller pore sizes are used to remove smaller particles and impurities.
Housing Design: Cobetter syringe filters have a sturdy housing that allows for easy and secure attachment to a syringe. Some filters also have color-coded housings for quick identification.
Sterility: Some Cobetter syringe filters are available in sterile versions for applications that require aseptic filtration.
Compatibility: These filters can be used with a variety of solvents and chemicals commonly used in laboratory settings.
Application-specific Filters: Cobetter offers specialized syringe filters designed for specific applications, such as HPLC (High-Performance Liquid Chromatography) sample preparation or biological sample filtration.
It’s essential to select the right syringe filter based on your specific filtration requirements, including the type of sample, the size and nature of particles you want to remove, and the compatibility of the filter material with your application.
Be sure to follow the manufacturer’s guidelines for proper use and disposal of syringe filters to ensure accurate and reliable results in your research or analytical work.
Nylon (Polyamide): Nylon membranes are widely used because of their versatility and compatibility with a broad range of solvents. They are suitable for both aqueous and organic solutions, making them a popular choice in many applications.
Polytetrafluoroethylene (PTFE): PTFE membranes are known for their chemical resistance and low protein binding properties. They are commonly used in applications involving aggressive chemicals and biological samples.
Polyvinylidene Fluoride (PVDF): PVDF membranes are popular in biological and pharmaceutical applications due to their chemical resistance and low protein binding characteristics.
Cellulose Acetate (CA): Cellulose acetate membranes are frequently used in general-purpose filtration, especially for aqueous solutions and biological samples.
Mixed Cellulose Ester (MCE): MCE membranes are hydrophilic and are commonly used in microbiological analysis and particle counting. They have good flow rates and particle retention capabilities.
Glass Fiber: Glass fiber membranes are used for applications that involve large particle filtration, pre-filtration, and clarification of viscous samples. They are highly resistant to most chemicals and have a high dirt-holding capacity.
