Then a sound source, e.g. a whistle, a 1700 Hz tuning fork (U10115) or a horn speaker (U8432680), is used to excite the powder into a regular pattern of nodes and antinodes. The effective length of the tube can be altered by means of a piston.\u003cbr\u003e\nLength:\t600 mm\u003cbr\u003e\nExternal diameter:\t20 mm\u003cbr\u003e\nInternal diameter:\t17 mm\u003cbr\u003eContents:\u003cbr\u003e\n1\tGlass tube with funnel\u003cbr\u003e\n1\tPlunger\u003cbr\u003e\n1\tFiller chute\u003cbr\u003e\n1\tWhistle\u003cbr\u003e\n1\tBottle of cork powder   \u003cli\u003e\n\t\tSecure online payment with SSL\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tExpert advice\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tFinancing available\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tEasy returns \u0026amp; exchanges\u003c\/li\u003e\n\t\u003cli\u003e\n\t\tInternational shipping available\u003c\/li\u003e\u003ch5\u003e\u003cspan\u003eSpecifications\u003c\/span\u003e\u003c\/h5\u003e\u003cul\u003e\n\u003cli\u003eUPC: Not Specified\u003c\/li\u003e\n\u003cli\u003eGTIN\/ITF Barcode: Not Specified\u003c\/li\u003e\n\u003cli\u003eUnits of Measure: Not Specified\u003c\/li\u003e\n\u003cli\u003eOverall Product Length: Not Specified in\u003c\/li\u003e\n\u003cli\u003eOverall Product Width: Not Specified in\u003c\/li\u003e\n\u003cli\u003eOverall Product Height: Not Specified in\u003c\/li\u003e\n\u003cli\u003eWeight Capacity: Not Specified lbs\u003c\/li\u003e\n\u003cli\u003eActual Product Weight: 0.55\u003c\/li\u003e\n\u003cli\u003eProduct Assembly: Not Specified\u003c\/li\u003e\n\u003cli\u003eProduct Installation: Not Specified\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: Not Specified\u003c\/li\u003e\n\u003cli\u003eCase QTY: Not Specified\/case\u003c\/li\u003e\n\u003cli\u003eCase Weight: Not Specified\u003c\/li\u003e\n\u003cli\u003eShips Via Freight: Not Specified\u003c\/li\u003e\n\u003cli\u003eProposition 65 Warning: Not Specified\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3B Scientific","offers":[{"title":"Default Title","offer_id":48198013354176,"sku":"1000814","price":142.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1403\/8729\/files\/1776959573406.jpg?v=1776959576","url":"https:\/\/tensnet.com\/products\/kundts-tube","provider":"TENSnet","version":"1.0","type":"link"}
