Built with heavy-wall borosilicate glass, it offers superior durability and safety, particularly during high-vacuum or high-temperature procedures. The tapered bottom is engineered to maximize sample recovery. By funneling liquids into a small, concentrated area, it ensures that almost no material is lost during evaporation or distillation.\u003c\/p\u003e\n\u003cp\u003eUnlike standard glassware, this flask is hand-blown to have uniform, thick walls. This makes it much more resistant to mechanical breakage and thermal shock, and it is rated for safe use under full vacuum. The 5 ml capacity is perfect for synthesizing or purifying high-value compounds where every milligram counts. Some of the practical applications include microscale distillation, rotary evaporation, concentration for analysis, and vacuum manifold reactions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUsed; great condition.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Chemglass","offers":[{"title":"Default Title","offer_id":48634232668412,"sku":"10025","price":118.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/chemglass-pear-shaped-flask-5-ml-heavy-wall-1420-outer-joint-lot-of-8-flasks-jointed-glassware-chemglass-110533.jpg?v=1767121527","url":"https:\/\/lifesciencestrading.com\/zh\/products\/chemglass-pear-shaped-flask-5-ml-heavy-wall-14-20-outer-joint","provider":"Life Sciences Trading","version":"1.0","type":"link"}
