The Wincom Flat-Bottomed Flask is a fundamental laboratory glass vessel designed for a wide range of heating, mixing, and storage applications. Featuring a spherical body with a stable, flat base and a long cylindrical neck, it allows the flask to stand upright securely on flat surfaces, heating mantles, or bench tops without the need for support rings. Forged from premium borosilicate glass, this flask provides excellent thermal shock resistance and superior chemical durability, making it an essential tool for everyday chemistry, biology, and research laboratories.

Technical Specifications

• Equipment Type: Narrow Neck / Wide Neck Flat-Bottomed Boiling Flask

• Material Composition: Premium Grade 3.3 Borosilicate Glass (Thermal shock resistant)

• Structural Profile: Spherical boiling body with a precision-ground, perfectly flat outer base

• Available Volumetric Capacities: Standard sizes (e.g., 50ml, 100ml, 250ml, 500ml, 1000ml, up to 2000ml or larger)

• Neck Style Options: Available in smooth straight-beaded rims for rubber stoppers, or with standard ground-glass joints for quick-fit assemblies

• Graduation Scale: High-visibility white or blue ceramic enamel markings indicating approximate volumes

• Chemical Resistance: High-level defense against water, universal solvents, concentrated acids, and alkaline solutions

Key Features

• Self-Standing Flat Base Geometry: Precision-engineered with a completely level, flat bottom that allows the vessel to stand upright independently on lab benches, hotplates, or open wire gauzes without tilting.

• Advanced Thermal Shock Resistance: Outfitted with a low coefficient of thermal expansion, preventing the glass from cracking or shattering when shifting from room temperature to direct liquid boiling states.

• Heavy-Duty Uniform Wall Distribution: Molded with a highly uniform wall thickness across the entire body, ensuring balanced heat distribution and preventing localized hot spots or structural pressure failures.

• Total Chemical and Acid Defense: The inert borosilicate matrix prevents trace mineral leaching or chemical reactions, ensuring pure and unadulterated results during sensitive fluid distillations.

• Fused High-Contrast Enamel Markings: Features a permanent matte marking patch and bold graduation text that resist scratching, washing, or fading under harsh chemical wash cycles.

Primary Applications

• Fluid Heating and Boiling: Safely boiling liquid compounds, solvents, and chemicals over laboratory hotplates or bunsen burner assemblies.

• Media and Solution Preparation: Mixing, dissolving, and storing chemical reagents, nutrient broths, and microbiological culture media on flat surfaces.

• Non-Vacuum Distillation Setups: Serving as a reliable boiling flask or receiving container in low-pressure distillation setups where stable stand-alone placement is required.

• Educational Academic Experiments: Providing high schools and colleges with a safe, sturdy, and highly versatile glass container for fundamental science practicals and fluid analysis.
