{"product_id":"tullgren-funnel-apparatus","title":"Tullgren Funnel Apparatus","description":"The Tullgren Funnel is a pivotal apparatus in the teaching of soil biology within the UK science curriculum. It provides an effective method for extracting and studying small soil-dwelling organisms such as insects, mites, and nematodes. This hands-on device allows students to observe soil biodiversity, understand ecological interactions, and appreciate the complexity of soil ecosystems.\n\nHow to use:\n\nIn a typical classroom or laboratory setting, a soil sample is placed on the perforated plate inside the funnel. A 12V, 50W heating lamp, positioned above the soil, generates heat that drives the organisms downwards, away from the light and heat source. These organisms then fall through the funnel into a collecting jar placed below, where they can be examined and studied.\n\nSupplied Components:\n\u003cul\u003e\n  \u003cli\u003eLamp holder - Securely holds the heating lamp above the soil sample and attaches to a retort rod for stability.\u003c\/li\u003e\n  \u003cli\u003e12V, 50W heating lamp bulb - Provides the necessary heat to drive organisms from the soil.\u003c\/li\u003e\n  \u003cli\u003eBlack plastic ring and funnel section - Ensures an efficient and contained setup for the soil sample and the collecting process.\u003c\/li\u003e\n  \u003cli\u003eCoarse and fine mesh set - Includes meshes with diameters of 2 mm, 4 mm, and 6 mm to support various soil types and sample sizes, enhancing the versatility of the funnel.\u003c\/li\u003e\n\u003c\/ul\u003e\nNot Supplied:\n\u003cul\u003e\n  \u003cli\u003eGlass beaker - Required to collect and observe the organisms that fall through the funnel.\u003c\/li\u003e\n  \u003cli\u003eRetort stand and rod - Necessary to hold the funnel and lamp setup securely in place.\u003c\/li\u003e\n\u003c\/ul\u003e\nAdditional Requirements:\n\u003cul\u003e\n  \u003cli\u003e4mm leads\u003c\/li\u003e\n  \u003cli\u003ePower supply\u003c\/li\u003e\n\u003c\/ul\u003e\nWith the Tullgren Funnel, educators can effectively engage students in practical scientific inquiry, fostering a deeper understanding of soil ecology and organismal biology.","brand":"EDULAB","offers":[{"title":"Default Title","offer_id":42700500566077,"sku":"107K01705","price":755.9,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/2583\/0205\/files\/edulab-science-general-lab-supplies-default-title-tullgren-funnel-apparatus-26761746874429.jpg?v=1770587396","url":"https:\/\/eduplaninternational.com\/products\/tullgren-funnel-apparatus","provider":"Eduplan International","version":"1.0","type":"link"}
