Humphrey Spiral

A Humphrey Spiral is a laboratory device used to separate cells or particles based on size and density. It consists of a transparent spiral tube filled with a liquid medium, where a mixture of cells or particles is introduced at the center. As the mixture flows along the spiral, larger or denser particles settle differently than smaller ones, allowing for separation. This method is gentle and efficient for isolating specific cell types, such as blood cells, without damaging them. The spiral's design ensures continuous flow and effective separation, making it useful in clinical and research settings.
