- HEAVY-WALL BOROSILICATE 3.3 CONSTRUCTION: Crafted from high-quality borosilicate 3.3 glass with a heavy-wall design to withstand the mechanical stress of vacuum distillation and rotary evaporation. The flask is precision-annealed to remove internal stress, ensuring superior thermal shock resistance and durability compared to standard glassware. Meets ASTM E438, Type 1, Class A standards.
- OPTIMIZED PEAR SHAPE FOR EFFICIENCY: Unlike round-bottom flasks, the tapered pear shape concentrates liquid at the bottom bulb, minimizing solvent hold-up and facilitating efficient evaporation. This design is specifically engineered for rotary evaporators (rotovaps), allowing for smoother boiling, reduced bumping, and easier removal of solid residues or small final volumes of 25mL.
- PRECISION GROUND GLASS JOINT: Features a standard taper 24/40 ground glass joint that ensures a vacuum-tight, leak-free seal. It is universally compatible with standard lab glassware, easily connecting to condensers, adapters, and rotary evaporator vapor ducts for secure solvent recovery setups.
- VERSATILE LAB APPLICATION: While specialized for rotary evaporation, this flask is also ideal for general organic chemistry distillation, solvent recovery, and drying solid products. The heavy-wall construction allows for safe direct heating (with care) and use in heating baths, making it a reliable workhorse for both educational and professional laboratories.
- SUPERIOR CLARITY & SAFETY: Hand-blown with uniform wall thickness to prevent weak spots. The high chemical resistance of the borosilicate glass ensures no contamination of your solvents or samples. Designed for safety and longevity, this flask offers a robust solution for daily lab use, reducing the frequency of breakage and replacement.
