Abstract

The invention relates to a method for extracting DNA, comprising the steps of: providing (400) a lysate (11) in a sample vessel (1), feeding (500) an DNA absorbing substance (15) to the sample vessel (1), closing (700) the sample vessel (1) by means of a wash filter element (3), feeding (600) a wash fluid (12) to the sample vessel (1) through the wash filter element (3), and discharging (700) the wash fluid (12) from the sample vessel (1) through the wash filter element (3). The DNA absorbing substance can be retained from the wash filter element (3).
