A method for diminishing variation between and/or within individual sheets of filter papers which are suitable for collecting samples of biological material, e.g. blood, is described. The method includes at least one of the following: subjecting the sheets of filter paper to gaseous substance containing at least 30 grams water per cubic meter and/or wetting the sheets of filter paper with water and subsequently drying the sheets of filter paper. According to tests, the above-described treatment significantly reduces the undesirable variation between results analyzed from sheets of filter paper and impregnated with same biological material for test purposes.

Method for improving quality and functionality of filter paper suitable for collecting biological samples

A biological component enrichment unit for the isolation, purification and/or determination of a biological component using particles () and/or another solid phase, which enrichment unit comprises at least one sample container () for the realization of the biological sample method. The enrichment unit comprises a lead-through structure (), such as a bushing () made up of one or several parts or a cover having one or several openings (). The lead-through structure and one or several sample containers can be brought into connection with one another so that, when the lead-through structure is placed on top of the sample container, a functional unit is formed for the realization of the biological method, such as for the binding of the component, the growing, isolation, purification, enrichment of the bacteria or cell or for another similar method.
