Description
Product Overview
Designed for versatile laboratory workflows, our borosilicate glass wide-mouth flasks combine robust construction with intuitive functionality. Ideal for mixing, heating, storing, and transferring reagents, these flasks are engineered for daily use in research, education, and industrial QC environments. The generous opening allows effortless addition of solids, insertion of stir bars, and smooth pouring—eliminating spills and improving workflow efficiency.
Key Features
Material Excellence: Crafted from high-purity 3.3 borosilicate glass conforming to ASTM E438 and USP Type I standards, ensuring exceptional resistance to thermal shock, chemical corrosion, and leaching across pH 0–12.
Wide-Mouth Design: The expanded neck diameter enables easy access for spatulas, pipettes, and magnetic stirrers—critical for reactions involving powders, suspensions, or viscous liquids.
Permanent Graduations: Clear, enamel-fired volume markings provide reliable approximate measurements for preparation and dilution tasks, though not intended for precise volumetric work.
Thermal Resilience: Withstands rapid temperature changes up to ΔT 150°C and is fully autoclavable at 121°C and 15 psi without warping, cracking, or loss of calibration.
Secure Sealing: Each flask is compatible with standard ground glass stoppers or polypropylene caps, offering reliable containment for volatile solvents, microbial cultures, or long-term storage.
Available Capacities
50 mL: Compact and lightweight, ideal for small-scale reactions and sample aliquots; stands 148 mm tall with a neck diameter suited for #13 stoppers.
100 mL: Balanced size for routine synthesis and solution preparation; measures 110 mm in height with a neck designed for #19 stoppers.
150 mL: Optimized for mid-volume mixing and titration prep; approximately 140 mm tall with a #22 stopper interface.
250 mL: Industry-standard capacity for most general lab applications; 170 mm in height with a #22 stopper for secure closure.
500 mL: High-capacity vessel for large-volume reactions, culture media, or solvent storage; stands 222 mm tall with a #27 stopper for enhanced vapor retention.
All models feature a flat, reinforced base for stability on lab benches and stir plates, and a beaded rim for improved grip and resistance to chipping during handling.
