FILTRATION COLUMNS FOR DIFFERENT VESSEL SIZES AND USE

摘要

This relates to filter columns for isolating nucleic acids. The filter colum n (1) is adapted for stable placement within the upper portion of standard plastic collection tubes of various sizes. The body of the filter column has a number of surfaces to accommodate placement within variously sized collectio n tubes. The filter column contains nucleic acid-specific filter which can be located at alternate regions within the filter column, providing different filter surface areas and loading volume capacities using the same column bod y. The filter column has an opening an upper end adapted to be sealed by a cap. A method for recovering nucleic acids using such filter column is also provide d.
