Sterile Bottle Top Vacuum Filtration with 0.22/0.45μm PES Membrane for Lab, 250ml Funnel + 250ml Receiver Lot of 12pcs

Desription:   Sterile bottle top vacuum filtration is a method used to filter and sterilize liquid samples. It involves using a vacuum pump to apply negative pressure to a filter unit with a membrane filter on top, which is then attached to a bottle or flask containing the liquid sample. The negative pressure forces the liquid through the filter membrane, removing any particulate matter or microorganisms that may be present in the sample. This technique is commonly used in microbiology and molecular biology applications, where a sterile environment is crucial to prevent contamination and ensure accurate results. It is especially useful for sterilizing large volumes of liquid samples, such as media, buffers, and culture supernatants. To perform sterile bottle top vacuum filtration, the filter unit and membrane filter must first be sterilized using methods such as autoclaving or gamma irradiation. The liquid sample is then poured into the sterile bottle or flask, and the filter unit is
