Heart-Shaped Flask Ground Glass Joint Borosilicate

Twin-lobe flask in borosilicate glass with standard ground glass joint. The heart-shaped geometry increases contact area with the heating bath compared to a conventional round-bottom flask — particularly useful in rotary evaporation and extract concentration.

Why use a heart-shaped flask

The twin-lobe profile improves evaporation efficiency on a rotary evaporator: greater film surface area and more uniform liquid agitation. In organic synthesis, it is also used for reactions requiring good inter-phase contact without additional mechanical stirring.

Standard in organic chemistry, pharmaceutical, and laboratory-scale synthesis laboratories.

Specifications

• Material: Borosilicate glass
• Joint: Standard ground glass
• Design: Heart-shaped, twin-lobe
• Seal: Vacuum-tight — compatible with stoppers, adaptors, and vacuum lines of the same cone size

Compatibility and assembly

The standard ground glass joint fits stoppers, vacuum adaptors, rotary evaporator heads, and other accessories of the same cone size. Suitable for use under vacuum in closed systems. Resistant to organic solvents and dilute acids in routine synthesis use.
