Disposable vacuum filtration kits are a filtration system commonly utilized in research labs for large sample separation and purification. They are designed to provide a convenient and efficient method for filtering liquids, removing particulates, and sterilizing solutions for tissue culture media, biological fluids and fixation buffers.  Each disposable vacuum filtration unit is individually packaged in sterile bag and available in various sizes and configurations.

The disposable filtration kit includes one membrane filter, graduated funnel made of clear polystyrene and a polystyrene receiving bottle or container. It combines with a vacuum pump to provide pressure differentials across the membrane filter allowing liquid to pass through and retain particulates on the membrane. The processed liquid is collected in the receiving bottle underneath. The filter membrane is made of materials, such as polyethersulfone (PES), Nylon, MCE etc. and comes in various pore sizes (0.10μm, 0.22μm and 0.45μm) to accommodate different applications.  There are multiple combinations of top funnel and receiving bottle volumes (250mL, 500mL and 1000mL).

Typical Applications:

• Sterile Filtration of Liquids: Used for aseptic filtration of culture media, buffers, and other liquid solutions to ensure a sterile environment for cell culture and microbiological applications.
• Biological Sample Clarification: Effective in removing particles and debris from biological samples such as cell culture supernatants, lysates, or fermentation broths to obtain clarified solutions for downstream processes.
• Water and Environmental Analysis: Employed in environmental monitoring and water analysis to filter out particulate matter, microbes, or contaminants from water samples prior to analysis.
• Pharmaceutical Filtration: Applied in pharmaceutical laboratories for the filtration of drug formulations, reagents, or solutions to ensure purity and eliminate contaminants.
• Laboratory Research and Experiments: Widely utilized in research laboratories for various applications such as sample preparation, purification, or clarification steps in experiments involving proteins, nucleic acids, and other biomolecules.
