The XXS2000 is a piezo-actuated micro diaphragm pump designed to deliver small amounts of liquids or gases. Customers who would like to test the pump for their application are now offered an Evaluation Kit. Besides the XXS2000 it contains an electronic pump control with integrated frequency generator and allows a quick and easy set-up of the pump. The XXS2000 is made of plastic and pumps liquids up to a few millilitres per minute. Barely larger than a coin of one inch in diameter, the pump weighs just three grams and is self-priming. These features and its low power consumption make the pump suitable for a wide scope of application fields ranging from diagnostics, drug discovery, or environmental monitoring to household appliances and miniaturised fuel cells. Due to its modular set-up, the pump may be adjusted to changing specification requirements. The wetted parts are micromolded from COC (cyclo-olefin co-polymer), a plastic material with good chemical resistance, and assembled by laser welding.
