Kontes Pear Shaped Flask 2-Neck 10 ml Heavy Wall CN-14/20 SN-10/18 - Lot of 4 Flasks

Precision Glassware for Small-Scale Synthesis

Upgrade your laboratory glassware with this set of four (4) Kontes 294750-0010 Pear Shaped Flasks. These flasks are specifically engineered for microscale organic chemistry, offering the perfect balance of versatility and rugged durability.

The pear-shaped design is superior to round-bottom flasks for distilling small volumes, allowing liquid to be reduced to near dryness with minimal loss. Crafted with heavy walls, these vessels provide exceptional mechanical strength, reducing the risk of breakage during vacuum operations, clamping, or washing.

Key Features & Benefits

• Maximized Recovery: The tapered pear geometry minimizes hold-up volume, making it ideal for concentrating solutions and recovering valuable microsamples.
• Heavy-Duty Construction: Features a heavy wall design that offers roughly 30% more glass thickness than standard flasks, ensuring safety under vacuum and longevity in the lab.
• Versatile 2-Neck Configuration: Equipped with a standard 14/20 center neck and an angled 10/18 side neck to accommodate thermometers, addition funnels, or gas inlets simultaneously.
• Precision Fit: Ground glass joints are manufactured to strict tolerances to ensure airtight, leak-free seals with your existing labware.
