Pressure type filter holders can be used for ultracleaning or sterilizing liquids and gases. AONE holders have been designed to maximize flow rates and to minimize holder resistance and can be used in either batch or continuous filtration procedures.

Advantages of Pressure Filtration
• Higher differential pressures are possible, resulting in higher flow rates. The pressure differential across the membrane is not limited to atmospheric pressure (≥14.7 psi)
• Unintentional contamination downstream of the membrane is minimized.

AONE 142mm membrane filter holder is used in various applications, primarily for filtering liquids and gases in laboratory and industrial settings. It supports the membrane filter during filtration processes, ensuring efficient and reliable separation of particles and contaminants. Key applications include sample preparation, sterilization, and particulate analysis in chemistry, biochemistry, pharmaceuticals, and water quality testing. Detailed Applications:

• Laboratory Filtration:
  • Sample Preparation: Membrane filter holders are used to prepare samples for various analyses, including HPLC solvent filtration, by removing particulate matter and ensuring the mobile phase is clean. 
  • Sterilization: They are used to sterilize liquids and gases by removing microorganisms. 
  • Particle Analysis: They help in determining the size and distribution of particles in a sample. 
  • Microbiological Testing: Membrane filters are used to capture microorganisms from liquid samples, allowing for their identification and quantification. 
• Industrial Filtration:
  • Water Quality Analysis: Membrane filter holders are employed in water quality testing to remove impurities and contaminants. 
  • Food and Beverage Industry: They are used for filtration in the production of beverages like beer, wine, and bottled water, as well as in dairy processing. 
  • Pharmaceutical Industry: Membrane filtration is crucial for producing high-purity water and other solutions used in pharmaceutical manufacturing. 
  • Electronics Manufacturing: They are used in the manufacturing of electronic devices and semiconductors, where ultra-clean water and chemicals are essential. 
• Other Applications:
  • Air and Gas Filtration: Membrane filter holders can be used to filter air and other gases, removing particulate matter and contaminants. 
  • Continuous Filtration: Some 142mm membrane filter holders are designed for continuous filtration, enabling the processing of larger volumes of liquid. 
  • Chemical Processing: They are used in various chemical processes to separate and purify liquids and gases. 
  • Research and Development: They play a vital role in research and development activities across various scientific disciplines.
