{"product_id":"boyle-mariotte-apparatus","title":"Boyle-Mariotte Apparatus","description":"The Boyle-Mariotte device is used to investigate the relationship between volume and pressure of a sealed volume of air at a constant temperature. It confirms the law of Boyle-Mariotte. \u003cbr\u003e \u003cbr\u003eProduct information:\u003cbr\u003eThe device consists of a closed plexiglass cylinder with a sliding piston that determines the enclosed volume, a scale for volume determination and a manometer for pressure determination. The piston is displaced by turning a threaded rod with crank. For safety reasons, the working cylinder is additionally surrounded by a protective cylinder made of acrylic glass. By means of a ventilation valve, pressure can be equalized with the ambient air in any piston position. Subsequent displacement of the piston generates overpressure or vacuum, depending on the initial situation. For safety reasons, an overpressure valve opens at a possible overpressure of 3.5 bar. The safety precautions described above allow safe experimentation in school lessons, in training and in internships at universities.\u003cbr\u003e \u003cbr\u003eTechnical data:\u003cbr\u003eWorking cylinder: \u003cbr\u003elength: 230 mm\u003cbr\u003eInner diameter: 40 mm\u003cbr\u003eMaximum pressure: 3,5 bar\u003cbr\u003episton: 30 mm x 40 mm Ø\u003cbr\u003evolume: 410 cm³\u003cbr\u003eDead volume V0: approx. 20 cm³\u003cbr\u003eScale: \u003cbr\u003elength: 200 mm\u003cbr\u003ePitch: 1 mm\u003cbr\u003ePressure gauge: \u003cbr\u003ePressure range: 0 - 4 bar\u003cbr\u003ediameter: 100 mm\u003cbr\u003etolerance class: 1\u003cbr\u003e \u003cbr\u003eRecommendation:\u003cbr\u003eThere is a complete experiment on the Boyle-Mariotte Law (Item No.: 8000589).
