Chemglass Pear Shaped Flask 100 ml Heavy Wall 2-Neck CN-14/20 SN-14/20 - Lot of 4 Flasks

Efficient Recovery and Durability for Mid-Scale Synthesis

Optimize your laboratory's distillation and synthesis capabilities with this set of four (4) Chemglass CG-1558-18 Pear Shaped Flasks. With a 100 mL capacity and heavy-wall construction, these flasks are designed to handle the demands of rotary evaporation and vacuum distillation while ensuring maximum sample recovery.

The pear-shaped geometry is specifically engineered to minimize hold-up volume, allowing liquids to be distilled down to very small residues compared to standard round-bottom flasks. Featuring two necks both ground to 14/20 precision, these vessels offer excellent versatility for connecting condensers, thermometers, or addition funnels using standard taper labware.

Key Features & Benefits

• Maximized Sample Recovery: The conical lower design reduces surface area at the bottom, making it ideal for concentrating solutions and recovering valuable products to near dryness.
• Robust Heavy Wall Design: Constructed with roughly 30% thicker glass than standard flasks, providing superior resistance to vacuum pressure and mechanical shock.
• Uniform Joint Compatibility: Features 14/20 standard taper joints on both the center and side necks, simplifying equipment setup by using a single joint size for all connections.
• Premium Material: Manufactured from low-expansion, Type I Class A borosilicate glass for high chemical resistance and thermal stability.
