Key features

• •Heavy-Duty Borosilicate Construction: Made of premium 3.3 borosilicate glass with heavy-wall design for superior heat resistance and durability. Withstands open-flame heating and rapid cooling cycles without cracking , ensuring long-lasting use in demanding lab settings.
• •Flat Bottom, Self-Standing Design: Flat bottom allows the 100 mL flask to stand upright on lab benches without a clamp or support. This provides convenient hands-free stability for setup, filling or storage, unlike typical round-bottom flasks. The design combines the stability of an Erlenmeyer with the even heating of a round-bottom.
• •24/40 Standard Taper Joint (Outer): Equipped with a 24/40 ground glass joint for secure, leak-free connections in distillation setups. The tapered outer joint is precision-fit and interchangeable, ensuring compatibility with other 24/40 lab glassware (condensers, adapters, etc.) for seamless integration into your organic chemistry apparatus.
• •Versatile Lab Applications: Ideal for use as a receiving flask in distillation apparatus and for boiling or heating liquids in organic chemistry experiments. The 100 mL size is perfect for small-scale syntheses, reflux setups, and educational lab demonstrations. A heavy-wall flat bottom flask offers safer heating than standard flat flasks and more convenience than round-bottom flasks during short-term storage or handling.
• •Quality Hand-Blown Craftsmanship: Hand-crafted by Laboy Glass to ensure uniform wall thickness and stress-free durability. Each flask is annealed at high temperature for extra strengthlabtservices.com.
