It's constructed from durable borosilicate glass, ensuring excellent chemical resistance and thermal stability. A key feature of this flask is its integrated 14\/20 standard taper outer joint, which provides a secure and greaseless connection point. This joint allows the flask to be easily attached to a Schlenk line, a vacuum\/inert gas manifold, or other compatible glassware, enabling tight sealing to exclude air and moisture from the reaction environment.\u003c\/p\u003e\n\u003cp\u003eIn great condition!\u003c\/p\u003e","brand":"Chemglass","offers":[{"title":"Default Title","offer_id":47283141673212,"sku":"9493","price":80.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/chemglass-airfree-schlenk-reaction-flask-25-ml-1420-outer-joint-jointed-glassware-chemglass-323499.jpg?v=1752369748","url":"https:\/\/lifesciencestrading.com\/zh\/products\/chemglass-airfree-schlenk-reaction-flask-25-ml-14-20-outer-joint","provider":"Life Sciences Trading","version":"1.0","type":"link"}
