Eine Vorrichtung (1) zur Extraktion eines Extraktionsgutes, insbesondere für eine Festphasenmikroextraktion, umfasst einen Extraktor (130) und eine Spitze (100) zum Durchdringen einer Trennschicht, wobei der Extraktor (130) mit der Spitze (100) verbunden ist. In einem Verfahren zur Extraktion eines Extraktionsgutes aus einem Behältnis mit einer Extraktionsvorrichtung (1) wird eine Trennschicht des Behältnisses mit einer Spitze (100) eines Extraktors (130) durchdrungen und das Extraktionsgut wird extrahiert. The device (1) has an extractor and a tip (100) that are provided for penetrating a separating layer. The extractor is connected to the tip and guided in a guide sleeve (150) along guiding direction, where external diameter of the tip is greater than external diameter of the extractor measured at right angles to the guiding direction. The external diameter of the guide sleeve measured at right angles to the guiding direction corresponds to the external diameter of the tip measured at right angles to the guiding direction. The extractor comprises a wire (110) and a hollow body. The wire is made of metal or metal alloy, stainless steel and chromium steel. The extractor is made of a physically active substance selected from one of activated carbon, polyacrylate, carbowax, polydivinylbenzene, carboxen and polydimethylsiloxane. An independent claim is also included for a method for extracting an extraction material from a container with an extraction device.
