Laboy Glass 50mL Single Neck Flat Bottom Boiling 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 50 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 50 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 strength​labtservices.com. This meticulous manufacturing process yields a reliable piece of lab glassware that meets ASTM laboratory standards for quality. Laboy is a trusted labware brand, delivering professional-grade glassware for reproducible results.

About Laboy Glass 50mL Single Neck Flat Bottom Boiling

The flat bottom flask is likely the other round bottom flask but with a flat bottom allowing it standing up flat surface as the flask can sit upright on its own. Capacity of 50mL with 24/40 glass ground taper joint. It can be used in heading during distillation, they are not as durable as round bottom flasks for heating better than Erlenmeyer flask which has have the sharp and vulnerable corners . Laboy glass flasks are heavy wall design, made by hand-blowing to ensure uniform wall thickness, and made of high-quality borosilicate glass and annealed at 800 degree Celsius, can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.
