Laboy Glass 250mL Round Bottom Boiling Flask, Single Neck Heavy Wall Borosilicate with 24/40 Joint – Heating, Reaction & Receiving Flask for

Heavy-Wall Borosilicate Glass Construction Crafted from premium 3.3 borosilicate glass with thick walls (3.5–5mm) for superior thermal and mechanical strength. Withstands direct flame heating, vacuum conditions, and extreme temperature changes without cracking. Standard 24/40 Taper Joint – Outer Joint Precision-ground 24/40 outer joint ensures airtight, leak-proof connections with condensers and adapters. Interchangeable with other standard lab glassware for seamless integration in organic chemistry setups. 250mL Capacity – Optimal for Medium-Scale Laboratory Reactions Commonly used in reflux setups, heating mantles, or receiving distillates. The 250 mL volume supports routine lab synthesis and chemical production tasks. Round Bottom for Uniform Heat Distribution Round bottom design promotes even heating, reduces hotspots, and minimizes stress fractures. Requires support via cork ring or clamp – recommended for controlled heating with mantles or water baths. Hand-Blown Quality – Stress Relieved & Impurity-Free Each flask is handcrafted and annealed at high temperatures for optimal clarity and structural integrity. No bubbles or contaminants—ensuring reproducibility in critical lab procedures.
