The OMSONS Pear-Shaped Flasks (also known as Kjeldahl or chicken-heart flasks) made from Borosilicate 3.3 glass. Their unique "V-shaped" bottom is specifically designed to facilitate the recovery of small volumes of liquid or solids, as the shape concentrates the material at the very bottom for easier pipetting or scraping. 
 
Key Features
  • Material: Low-expansion Borosilicate 3.3 glass, providing excellent thermal shock resistance and chemical durability.
  • Design: Features a tapered pear-shaped body with a single narrow neck, typically finished with a ground glass joint (socket).
  • Standards: Manufactured in compliance with international standards such as DIN 12383.
  • Joint Sizes: Commonly available with standard taper joints like 14/23, 19/26, or 24/29 to allow airtight connections with condensers and rotary evaporators. 
Primary Applications
  • Rotary Evaporation: Ideal for evaporating solutions to dryness because the rounded V-shape allows for more efficient scraping of solid residues than a standard round-bottom flask.
  • Small-Scale Reactions: The concentrated bottom area makes them perfect for micro-scale semi-micro synthetic chemistry where only small amounts of reagents are used.
  • Distillation: Often used as the boiling or receiving flask in semi-micro distillation assemblies. 
Common Capacities
These flasks are typically available in smaller sizes for precision work:
  • 10 ml to 100 ml: Standard for micro-chemistry.
  • 250 ml to 500 ml: Used for larger-scale rotary evaporation.
