Description

• This pear-shaped single-neck flask is manufactured from high-quality borosilicate glass 3.3, offering excellent chemical resistance, thermal shock resistance, and optical clarity. Its pear-shaped body provides a larger heating surface and promotes efficient mixing and uniform heat distribution, making it ideal for distillation, reflux, extraction, and synthesis. The 19/22 standard taper joint ensures compatibility with a wide range of laboratory glassware, including condensers, adapters, and stoppers.

  Key Features

  • Laboratory-Grade Borosilicate Glass 3.3: High chemical durability and thermal stability for routine and demanding laboratory applications.

  • Pear-Shaped Design: Rounded body with a tapered neck optimizes heating surface area and improves mixing efficiency.

  • Single Neck Configuration: Simplifies setup and reduces the risk of cross-contamination.

  • 19/22 Standard Taper Joint: Precision-ground conical interface ensures a secure, leak-free fit with compatible glassware.

  • Multiple Capacity Options: Available from 5ml to 200ml.

  • Excellent Thermal Shock Resistance: Withstands typical laboratory temperature changes without cracking.

  • Chemical Resistance: Resists most common acids, bases, solvents, and reagents under normal laboratory conditions.

  • Clear Borosilicate Construction: Allows easy visual monitoring of contents and reaction progress.

  • Uniform Wall Thickness: Promotes even heating and reduces stress points for enhanced durability.

  • Reusable and Long-Lasting: Designed for repeated use with proper handling and care.

  • Versatile Applications: Ideal for distillation, reflux, extraction, synthesis, and general chemistry procedures.
