Description
The Kimble Kontes Bantam-Ware® (Part Number 294250-0025) Pear-Shaped Flask is a specialized 25 mL vessel designed specifically for microscale organic synthesis and distillation. As part of the “Bantam-Ware” series, this flask is engineered for operations where sample sizes are small (typically <50 mL) and maximizing yield is critical.
The 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.
Manufactured 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.
Used, in great condition.
