- 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 35/20 Ball Joint – Easy Assembly with Pinch Clamp Precision-formed 35/20 ball joint allows quick and secure connections between lab components. Its spherical interface enables fast setup and disassembly, especially in vertical or angled assemblies. Designed to be held in place using a pinch clamp for a tight, reliable seal in distillation, vacuum, or reflux systems.Compatible with standard 35/20 ball-and-socket glassware systems in distillation, reflux and vacuum manifolds.
- 2000mL Capacity – Designed for Large-Scale Chemistry Setups Used for multi-step distillations, batch reactions, or vacuum applications. The 2000 mL volume is suited for industrial labs, scale-up processes, and preparative chemistry.
- 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.
