centriframat

A centrifugramat is a piece of laboratory equipment used in centrifugation. It is essentially a filter paper or membrane designed to be placed within a centrifuge tube. Its purpose is to retain solid particles while allowing the liquid supernatant to pass through. This facilitates the separation of solids from liquids in a more efficient and clean manner compared to traditional decantation methods.

When a centrifugramat is used, the sample is placed in the centrifuge tube on top of the filter. After centrifugation, the solid material is trapped by the centrifugramat at the bottom of the tube, while the liquid can be easily poured off or pipetted away. This is particularly useful in applications where the solid component needs to be collected for further analysis or purification, or when a clear liquid is required. The material of the centrifugramat can vary depending on the application, with different pore sizes available to suit the particle size being separated. They are often disposable, preventing cross-contamination and simplifying the workflow. The use of a centrifugramat can improve the reproducibility of experiments by ensuring consistent separation of solids.
