Flat Bottom Borosilicate Glass Boiling Flask - 100ml 150ml 250ml

Flat-bottom borosilicate boiling flasks in 100 ml, 150 ml and 250 ml capacities feature a single short neck with standard-taper ground joints (19/26, 24/29 or 29/32) for secure glass-glass connections. The low-expansion glass withstands direct heating, rapid temperature swings and most reagents, making these flasks reliable workhorses for solution preparation, distillation set-ups and general boiling tasks in research, teaching and industrial labs.

Features:
• Material: Borosilicate glass resists thermal shock and chemical attack
• Joint: Ground 19/26, 24/29 or 29/32 ensures leak-free integration with standard labware
• Capacity: 100 ml, 150 ml or 250 ml suits small to mid-scale reactions
• Transparency/Visibility: Clear glass provides unobstructed view of contents
• Ergonomic/Operational feature: Flat bottom stands securely on heating mantles or plates
• Reusability/Durability: Autoclavable and reusable for long service life

Ideal Uses:
• Boiling, evaporation or reflux studies in research/non-medical applications
• Solution preparation and reagent storage in teaching laboratories
• Distillation receivers or adapters in pilot-scale chemical processes

Package Includes:
• 1 borosilicate flat-bottom boiling flask in selected capacity and joint size

Notice:
• Dimensional tolerance ±0.3 mm on joint and capacity
