As part of the \"Bantam-Ware\" series, this flask is engineered for operations where sample sizes are small (typically \u0026lt;50 mL) and maximizing yield is critical.\u003c\/p\u003e\n\u003cp\u003eThe unique pear-shaped (or tapered) geometry distinguishes it from standard round-bottom flasks. This design allows liquids to pool into a smaller, deeper cone at the bottom, which significantly aids in the recovery of valuable products using a syringe or capillary pipette. It also minimizes the \"dead volume\" left behind during evaporation, making it the preferred choice for concentrating expensive reagents or final products.\u003c\/p\u003e\n\u003cp\u003eManufactured from Type I, Class A Borosilicate Glass (33 expansion), the flask features a 14\/20 Standard Taper Outer Joint. This smaller joint size is standard for microscale kits, ensuring compatibility with Bantam-Ware condensers, distillation heads, and vacuum adapters. The heavy-wall construction provides the mechanical strength needed to withstand vacuum applications without implosion risks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUsed, in great condition.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Kimble Kontes","offers":[{"title":"Default Title","offer_id":48650294100220,"sku":"10113","price":80.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/kontes-bantam-ware-pear-shaped-flasks-25-ml-1420-outer-joint-lot-of-8-flasks-jointed-glassware-kimble-kontes-862191.jpg?v=1767994875","url":"https:\/\/lifesciencestrading.com\/products\/kontes-294250-0025-pear-shaped-flasks-25-ml-14-20-outer-joint","provider":"Life Sciences Trading","version":"1.0","type":"link"}
