{"product_id":"stefan-boltzmann-lamp","title":"Stefan-Boltzmann lamp","description":"Product Information: ..\u003cbr\u003eHigh temperature source designed to produce thermal radiation, for investigating how such radiation depends on the temperature and to confirm the Stefan-Boltzmann law. The tungsten filament represents a good approximation of a point source of heat radiation and is thus highly suitable for investigating the inverse square law. The temperature of the lamp can be determined from the resistance of the filament. To minimize voltage loss the lamp contacts are soldered to the connectors.\u003cbr\u003eRefer also to experiments UE4050100 and UE4050200.","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":49419116052757,"sku":"3BS1008523","price":304.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/U8490050_01_1200_1200_Stefan-Boltzmann-lamp.jpg?v=1761027020","url":"https:\/\/unitedsupplycorp.com\/products\/stefan-boltzmann-lamp","provider":"United Supply Corp.","version":"1.0","type":"link"}
