Specification Brand : LABOY BulletPoint1 : 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. BulletPoint2 : Standard 45/50 Taper Joint – Outer Joint Precision-ground 45/50 outer joint ensures airtight, leak-proof connections with condensers and adapters. Interchangeable with other standard lab glassware for seamless integration in organic chemistry setups. BulletPoint3 : 2000mL Capacity – Built for Industrial & High-Volume Applications Supports large-volume heating, solvent recovery, or batch reactions. The 2000 mL volume is favored in chemical manufacturing, pilot plant operations, and advanced lab synthesis. BulletPoint4 : 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. BulletPoint5 : 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.
