Aldrich 250 ml 3-Neck Angled Round Bottom Flask 24/40 Outer Joint

Equip your laboratory bench with the Aldrich Z418692-1EA 250 mL Three-Neck Round Bottom Flask. Engineered for demanding organic synthesis and complex distillation setups, this multi-neck vessel provides the flexibility required when simultaneous stirring, temperature monitoring, and reagent addition are critical to your reaction's success.

Manufactured from premium borosilicate glass, this flask delivers the exceptional chemical resistance and thermal shock durability expected from Sigma-Aldrich glassware. The angled side necks offer convenient, ergonomic access for probes and dropping funnels while ensuring ample clearance for your primary central apparatus, such as an overhead stirrer or a fractionating column.

Key Features & Benefits

• Angled 3-Neck Configuration: The angled side necks allow for the simultaneous insertion of multiple accessories without spatial interference, keeping the center neck unobstructed for main distillation columns or stirrers.
• Standardized 24/40 Joints: All three necks are equipped with precision-ground 24/40 Standard Taper outer joints, guaranteeing a secure, leak-free fit with a vast array of standard laboratory glassware.
• Uniform Heat Distribution: The classic spherical geometry maximizes surface area contact within heating mantles or oil baths, promoting efficient heat transfer and preventing localized hot spots.
• Exceptional Durability: Crafted from high-quality, low-expansion borosilicate glass to withstand sudden temperature changes, harsh solvents, and rigorous daily use.
