sterile syringe filter

A sterile syringe filter is a crucial laboratory tool designed for the efficient filtration and sterilization of liquid samples. These precision-engineered devices consist of a membrane filter housed within a durable plastic housing, specifically designed for single-use applications in laboratory and research settings. The filter utilizes advanced membrane technology to effectively remove particles, microorganisms, and contaminants from solutions. Available in various pore sizes ranging from 0.22 to 0.45 microns, these filters ensure optimal filtration performance for different applications. The device's design incorporates a Luer-lock or Luer-slip connection, making it compatible with standard syringes and enabling secure, leak-free filtration processes. The membrane material options include polyethersulfone (PES), polytetrafluoroethylene (PTFE), nylon, and cellulose acetate, each offering specific advantages for different types of samples. Sterile syringe filters are individually packaged and gamma-irradiated to maintain sterility, making them ideal for critical applications in pharmaceutical research, biologics preparation, and analytical chemistry.

Popular Products

Sterile syringe filters offer numerous practical benefits that make them indispensable in laboratory settings. First, their single-use nature eliminates cross-contamination risks and the need for time-consuming cleaning procedures. The filters feature low protein binding characteristics, ensuring minimal sample loss during filtration, which is particularly valuable when working with precious or limited samples. Their high-flow-rate design significantly reduces processing time, allowing for efficient sample preparation and increased laboratory productivity. The filters' robust construction ensures consistent performance under various pressure conditions, while their transparent housing enables visual confirmation of filtration progress. The variety of membrane materials available allows users to select the most suitable option for their specific application, whether working with aqueous solutions, organic solvents, or protein-containing samples. The standardized Luer connections ensure universal compatibility with laboratory equipment, eliminating the need for additional adapters or specialized tools. The gamma-sterilized packaging provides immediate ready-to-use convenience while maintaining product integrity. Additionally, these filters feature low extractables and minimal hold-up volume, ensuring sample purity and maximizing recovery. The ergonomic design facilitates easy handling and reduces user fatigue during multiple filtration procedures, while the built-in pre-filters extend the filter's life by preventing premature clogging.

Superior Filtration Efficiency

Superior Filtration Efficiency

The sterile syringe filter's advanced membrane technology delivers exceptional filtration efficiency through its precisely controlled pore size distribution. This feature ensures consistent and reliable particle retention while maintaining high flow rates throughout the filtration process. The membrane's unique structure combines depth filtration with surface filtration mechanisms, effectively capturing particles across a broad size range. The filter's design incorporates multiple layers of filtration media, including a pre-filter layer that protects the main membrane from premature clogging by larger particles. This multilayer approach significantly extends the filter's capacity and maintains optimal performance throughout its use. The membrane's uniform pore size distribution ensures that all filtered liquid meets the same high standard of clarity and purity, making these filters particularly valuable in applications requiring stringent quality control.
Enhanced Sample Protection

Enhanced Sample Protection

The sterile syringe filter's design prioritizes sample integrity through multiple protective features. Each filter undergoes rigorous quality control and is individually packaged in gamma-irradiated containers, ensuring absolute sterility until the moment of use. The filter housing is constructed from high-grade, chemically resistant materials that prevent any interaction with the sample, maintaining its original composition. The low protein binding characteristics of the membrane materials minimize sample loss, particularly crucial when working with valuable biological samples. The filter's design also incorporates special flow channels that reduce dead volume and sample hold-up, maximizing sample recovery and ensuring optimal use of precious materials. These features combine to provide comprehensive sample protection throughout the entire filtration process.
Versatile Application Compatibility

Versatile Application Compatibility

The sterile syringe filter's versatile design makes it suitable for a wide range of laboratory applications. The availability of different membrane materials and pore sizes allows users to optimize filtration parameters for specific sample types and requirements. The filters excel in applications ranging from HPLC sample preparation to cell culture media sterilization. Their robust construction maintains integrity under various pressure conditions, making them suitable for both manual and automated filtration systems. The standardized Luer connections ensure seamless integration with existing laboratory equipment, while the filter's compact size makes it ideal for space-constrained environments. The device's versatility extends to its chemical compatibility, with different membrane options suitable for aqueous solutions, organic solvents, and aggressive chemicals.
