It features a vertical center neck and one angled side neck, both equipped with 14\/20 standard taper joints. \u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eThe primary advantage of the angled side neck is that it allows for the simultaneous introduction of reagents or the use of a thermometer while a condenser or stirrer is attached to the center neck. This geometry prevents the crowding of glassware, which is especially important in the confined space of a 25 ml microscale setup.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003eFabricated from high-quality borosilicate glass, this flask offers excellent chemical resistance and durability. The standard wall construction is optimized for rapid heating, making it highly efficient when used with heating mantles or sand baths. This flask is frequently used in organic synthesis research for performing reactions on small quantities of material, typically between 5 ml and 15 ml. Its 2-neck design is ideal for refluxing under an inert atmosphere or for reactions requiring a constant drip-feed of a reagent via an addition funnel.\u003c\/p\u003e\n\u003cp\u003eUsed, in great condition.\u003c\/p\u003e","brand":"Ace Glass","offers":[{"title":"Default Title","offer_id":48846124024060,"sku":"10539","price":47.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/ace-glass-2-neck-round-bottom-flask-25-ml-1420-joints-angled-jointed-glassware-ace-glass-236004.jpg?v=1773254979","url":"https:\/\/lifesciencestrading.com\/zh\/products\/ace-glass-9464-06-2-neck-round-bottom-flask-25-ml-14-20-joints-angled","provider":"Life Sciences Trading","version":"1.0","type":"link"}
