Microcups

Microcups, also known as microfiltration cups, are small, disposable devices used in laboratories and medical settings for sample preparation and filtration. They are designed to separate particulate matter from liquids on a microscopic level. Typically made from plastic materials such as polypropylene or polycarbonate, microcups feature a porous membrane at their base.

The primary function of a microcup is to pass a liquid sample through its membrane, retaining larger particles while allowing smaller molecules and the liquid itself to pass through. This process is useful for a variety of applications, including concentrating small particles, removing unwanted debris from solutions, or preparing samples for further analysis such as spectroscopy or chromatography.

Microcups come in various pore sizes, allowing for precise control over the filtration process. Smaller pore sizes can retain very fine particles, while larger pore sizes are suitable for removing larger debris. Their small size and disposable nature make them convenient for single-use applications, minimizing the risk of cross-contamination and reducing the need for cleaning and sterilization. They are often used in conjunction with standard laboratory equipment like centrifuges or vacuum manifolds.
