Wilmad Lab Glass 2-Neck Pear Shaped Flask 100 ml 14/20 Joints

The Wilmad-LabGlass 2-Neck Pear Shaped Flask is a high-performance piece of laboratory glassware designed for specialized synthesis and evaporation tasks. Its unique pear-shaped geometry is engineered to provide maximum sample recovery, particularly during the concentration of small volumes of material, as the narrow base allows for easy pipette access or retrieval with a spatula.

Core Specifications & Design

• Capacity: 100 ml. A standard size for medicinal chemistry, natural product extraction, and small-scale organic synthesis.

• Joint Configuration: Features 14/20 Standard Taper outer joints. The 14/20 size is common in microscale and semi-microscale glassware kits (often referred to as "24/40's smaller cousin").
• Neck Orientation: Designed with one vertical center neck and one angled side neck (usually at 20°). This allows for the simultaneous use of a condenser and a secondary tool, such as a thermometer, addition funnel, or gas inlet adapter.
• Material: Fabricated from heavy-wall borosilicate glass (Type I, Class A). This construction is specifically chosen for its ability to withstand the mechanical stresses of high-vacuum applications and its resistance to thermal shock.
• The 100 ml 2-Neck Pear Shaped Flask is a high-quality, heavy-walled unit. It is the best choice for high-vacuum distillation or air-sensitive reactions where the absolute precision of the 14/20 ground glass joints is critical for maintaining a leak-proof seal.

Used, in great condition.
