{"product_id":"van-de-graff-generator-dual-drive-vandgf1-dd","title":"Van De Graff Generator, Dual Drive - VANDGF1-DD","description":"This large van de Graaff generator uniquely offers alternative drive\nmodes, either hand-cranked or motor driven. Excellently constructed, the\ngenerator reliably delivers charge and sparks 10cm long and more\nimmediately on setting it in motion, even under high humidity conditions.\nIn hand-cranked mode the amount of charge generated can be seen to\nincrease at higher cranking speeds, while the much faster motor-driven\nmode delivers a fast succession of sparks. The generator is 76cm high\nand features a 28cm diameter polished steel sphere, which is less\nvulnerable to dents and scratches than comparably sized aluminum\nspheres. A further unique feature of this generator is a built-in lamp close\nto the bottom of the belt that delivers a small amount of UV light when\nturned on. This can be seen to increase the charge production. A set of\naccessories is included, containing a discharge wand with a grounding\ncord, an electric plume, an electric whirl, a discharge bulb, a cord for\nconnecting other electrostatic demonstration items, a spare charge belt\nand a spare motor drive belt. The generator measures 38cm x 23cm x\n76cm.\u003cbr\u003e\u003cb\u003eAdditional Info:\u003c\/b\u003e Van De Graaff Generator, Dual Drive\u003cbr\u003e\u003cb\u003ePackage Size(L x W x H):\u003c\/b\u003e 17 X 13 X 22 (IN)\u003cbr\u003e\u003cb\u003eCategories:\u003c\/b\u003e Physics, Electricity\u003cbr\u003e\u003cb\u003eHTS Code:\u003c\/b\u003e 9023.00.0000\u003cbr\u003e\u003cb\u003eUNSPSC:\u003c\/b\u003e 6.01e+007\u003cbr\u003e\u003cb\u003eCountry Of Origin:\u003c\/b\u003e CHINA","brand":"United Scientific Supplies","offers":[{"title":"Default Title","offer_id":37110348251305,"sku":"VANDGF1-DD","price":625.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0401\/5452\/9953\/products\/vandgf1-dd-van-de-graaff-dual-drive-generator.jpg?v=1709868947","url":"https:\/\/labproinc.myshopify.com\/products\/van-de-graff-generator-dual-drive-vandgf1-dd","provider":"Lab Pro Inc","version":"1.0","type":"link"}
