{"product_id":"x-ray-apparatus","title":"X-Ray Apparatus","description":"\u003cbr\u003eProduct Information: ..\u003cbr\u003eThe experiment chamber is contained in a closed, radiation-proof housing with a transparent synthetic-glass shield. If the synthetic-glass shield is opened, the high-voltage source for the X-ray tube is deactivated automatically. The high-vacuum X-ray tube with a directly heated tungsten cathode and copper anode is positioned in a borosilicate glass chamber with a thinwalled, concave ray emission window. A lead-glass hood with a collimator causes X-rays to emerge in parallel with the experiment plane and provides a shield against scattered radiation. The horizontal counter-tube goniometer consists of a central sample holder and a swiveling arm. In the form of a slide tray, this arm serves as a mount for the Geiger-Müller tube (U19201), ionization chamber (U19208) as well as experimental devices in slide format or on a 5 cm x 5 cm base plate (for example, from U19205, U19206, U19207). The swiveling arm can be rotated manually independently of the sample holder, or at a fixed mutual angle with a ratio of 2:1, for instance, for experiments involving Bragg’s reflection. The device is equipped with angle and millimeter scales, position markings for experimental devices, as well as radiation-proof bushings for cables and hoses.\u003cbr\u003e\u003cbr\u003eSpecifications: ..\u003cbr\u003eAnode voltage:\t20\/30 kV; selectable, electronic stabilisation\u003cbr\u003eEmission current: \t0 to 80 μA; continuously adjustable with electronic stabilisation\u003cbr\u003eCathode heating:\t4 V, 1 A\u003cbr\u003eFocal spot:\t5 mm x 1 mm\u003cbr\u003eAnode material:\tCu\u003cbr\u003eLead-glass collimator:\tradiation emission aperture with 5-mm Ø\u003cbr\u003eRay divergence:\tbetter than 10°\u003cbr\u003e \t \u003cbr\u003eCharacteristic\u003cbr\u003eradiation wavelength:\tCu -Kα: 154 pm, Cu -Kβ: 138 pm\u003cbr\u003e \t \u003cbr\u003eCounter-tube goniometer:\tswiveling ranges: 0°, +10° to +130° and -10° to +130° relative to the ray axis\u003cbr\u003eAngular coupling:\tindependent of the sample holder or with a ratio of 2:1\u003cbr\u003e \t \u003cbr\u003eMeasurement accuracy\u003cbr\u003eof Bragg angle 2θ:\t5 arc minutes\u003cbr\u003e \t \u003cbr\u003eTimer:\t0 to 55 minutes, continuously adjustable\u003cbr\u003ePower consumption:\t100 VA\u003cbr\u003eDimensions X-Ray apparatus:\tapprox. 250 mm x 370 mm Ø\u003cbr\u003eDimensions X-Ray tube: \tapprox. 100 mm x 32 mm Ø\u003cbr\u003eWeight:\tapprox. 9 kg","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":49419051565333,"sku":"3BS1000657","price":17032.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/U192001_01_1200_1200_X-Ray-Apparatus.jpg?v=1761020787","url":"https:\/\/unitedsupplycorp.com\/products\/x-ray-apparatus","provider":"United Supply Corp.","version":"1.0","type":"link"}
