The MEDILAB Flask, Round/Flat Bottom, Three Necks (Parallel) is a precision-engineered laboratory reaction vessel designed for multi-port operations in chemical synthesis, distillation, refluxing, and heating processes. Featuring three parallel necks for simultaneous attachments, it enables efficient sampling, reagent addition, temperature monitoring, and mechanical stirring. Its robust borosilicate glass construction ensures high thermal resistance, chemical durability, and consistent reliability in demanding scientific and industrial environments, making it essential for research labs, pharmaceutical R&D, and chemical processing workflows.

Key Features

• Three Parallel Necks for simultaneous use of condensers, thermometers, dropping funnels, stirrers, or other lab accessories.
• Available in Round or Flat Bottom Design, offering suitability for heating mantles, hot plates, or support systems.
• Premium Borosilicate Glass 3.3 ensures excellent temperature stability and chemical resistance.
• Uniform Wall Thickness for safe heating, pressure stability, and extended service life.
• High Thermal Shock Resistance supports rapid heating and cooling cycles.
• Leak-proof Standard Joints compatible with international laboratory glassware systems.
• Crystal-Clear Transparency for easy observation of reactions, mixing, and colour changes.
• Autoclavable & Reusable, making it cost-effective for long-term laboratory use.
