A device ( 10 ) for reducing noise and heat emissions from a laboratory instrument in a laboratory, comprising a casing ( 20 ) with sound-absorbing walls ( 240 ), wherein the casing ( 20 ) forms an interior space ( 210, 220 ) for accommodating the laboratory instrument. At least one of the sound-absorbing walls ( 240 ) has an air inlet ( 30 ). The device ( 10 ) further has a flue ( 40 ) arranged on one of the sound-absorbing walls ( 240 ), so that the interior space ( 210, 220 ) of the casing ( 20 ) can be vented via the air inlet ( 30 ) and the flue ( 40 ). During operation of the laboratory instrument situated in the interior space ( 210, 220 ) of the device ( 10 ), the sound generated by the laboratory instrument is absorbed by the walls, so that essentially no noise, or only significantly reduced levels of noise, generated by the laboratory instrument can escape the device ( 10 ). The walls ( 240 ) and their connections are also designed in such a way that essentially no heat generated by the laboratory instrument can escape the device ( 10 ). The air that flows into the interior space through the one air inlet ( 30 ), or preferably through several air inlets ( 30 ), being again evacuated through the flue ( 40 ) makes it possible to remove waste heat produced by the laboratory instrument from the device. Such a device ( 10 ) makes it possible to operate a laboratory instrument in a laboratory without people located in the laboratory being significantly impaired by waste heat and/or noise from the laboratory instrument.
