(EN) To form a layer (11) separating two volumes of aqueous solution, especially a biolayer lipid membrane (BLM) there is used an apparatus comprising elements defining a chamber (7), the elements including a body (2) of non-conductive material having formed therein at least one recess (5) opening into the chamber, the recess containing an electrode (21). A pre-treatment coating of a hydrophobic fluid is applied to the body across the recess. Aqueous solution, having amphiphilic molecules added thereto, is flowed across the body to cover the recess so that aqueous solution is introduced into the recess from the chamber and a layer of the amphiphilic molecules forms across the recess separating a volume of aqueous solution introduced into the recess from the remaining volume of aqueous solution.
(ZH) 为了形成分隔两个体积水溶液的层(11)，尤其是生物层脂质膜(BLM)，使用了包含限定腔室(7)的元件的装置，所述元件包括其中形成有至少一个通向所述腔室的凹槽(5)的非导电性材料的主体(2)，所述凹槽包含电极(21)。在跨越所述凹槽的所述主体上涂布疏水性流体预处理涂料。其中添加有两性分子的水溶液流过所述主体而覆盖所述凹槽，从而使水溶液由所述腔室导入所述凹槽，两性分子层跨越所述凹槽形成，并且将导入所述凹槽中的水溶液的体积与水溶液的其余体积隔开。
