Disposable Syringe Filter

A disposable syringe filter is a filtration device that is designed to be used once and then discarded. It typically consists of a plastic housing with a filter membrane that is attached to the end of a syringe.

Features of disposable syringe filter

1. Filter membrane: The filter membrane is the core component of the disposable syringe filter, responsible for the actual filtration process. Filter membranes are available in various materials and pore sizes, depending on the specific application requirements. It is made of materials such as nylon, PTFE, PVDF, or regenerated cellulose. The membrane is designed to remove contaminants such as particles, microorganisms, and other impurities from liquids.
2. Housing material: The housing of the disposable syringe filter is usually made of a durable, chemically-resistant plastic material such as polypropylene. This ensures that the filter can withstand exposure to a wide range of chemicals and solvents.
3. Construction: Disposable syringe filters are typically made with a plastic housing that contains the filter membrane. The housing often has luer-lock or luer-slip connections to easily attach to standard syringe tips.
4. Compatibility: compatible with a variety of different liquids, including aqueous solutions, organic solvents, and aggressive acids and bases. The type of filter membrane used will depend on the nature of the liquid being filtered.
5. Pore Size: Disposable syringe filters come in different pore sizes, which determine the size of particles that can be retained or filtered from the liquid sample.
6. Size: disposable syringe filters are available in a range of different sizes, typically ranging from 4mm to 25mm in diameter. The size of the filter chosen will depend on the volume of liquid being filtered and the type of application.
7. Sterilization: Some disposable syringe filters are pre-sterilized, making them suitable for applications requiring aseptic filtration, especially those involving sensitive samples or cell cultures.
8. Single-Use: As the name suggests, disposable syringe filters are intended for one-time use only. After filtration, they are discarded, which helps prevent cross-contamination between samples and simplifies the cleanup process.
9. Ease of use: very easy to use. They can be attached to a standard luer-lock syringe and the liquid to be filtered can be drawn through the membrane by applying gentle pressure to the plunger of the syringe.

Applications

1. Sample preparation: used for removing particles and other contaminants from samples before analysis. They are commonly used for preparing samples for HPLC, GC, and other analytical techniques.
2. Sterilization: Disposable syringe filters with sterilizing membranes are used for sterilizing small volumes of liquids such as media, buffers, and culture supernatants. They are commonly used in microbiology and biotechnology labs.
3. Clarification: Disposable syringe filters are used for clarifying small volumes of liquids by removing particulate matter. They are commonly used for preparing samples for electron microscopy, protein purification, and nucleic acid isolation.
4. Filtration of aqueous and organic solutions: Disposable syringe filters are used for filtering both aqueous and organic solutions. The filters come in different materials and pore sizes, making them suitable for various applications.
5. Removal of endotoxins: with low protein binding and endotoxin removal membranes are used for removing endotoxins from samples. They are commonly used in the pharmaceutical and biotechnology industries.

Unlike Advanced syringe filters and low protein binding syringe filters, which are transparent in color, the disposable syringe filter is designed with a color code.

The maximum working pressure is 6.2 bar and the filtration speed is fast. The filter structure of the standard female Luer lock and male roller accessories is adopted.

Materials and sizes are commonly used in laboratories and can be easily injected with an HPLC syringe. Very low HPLC can be used to extract materials(Nylon, PTFE, PES, PVDF, Hydrophilic PTFE, and Hydrophilic PVDF).

This series of products has lower cost and price and has excellent filtration efficiency. A disposable syringe filter is suitable for any customer’s needs.
