Our Erlenmeyer Flasks, made from borosilicate glass 3.3, are ideal for laboratory applications requiring chemical and thermal resistance.

Available in volumes ranging from 25ml to 5000ml, these flasks feature a narrow mouth and are individually sold to suit a variety of experimental setups. Each flask complies with ISO 1773 and ASTM E-438 Type I standards, ensuring quality and consistency across all sizes.

Material & Construction

Manufactured from high-quality borosilicate glass 3.3, these flasks offer outstanding resistance to chemical corrosion and thermal shock. A reinforced thick rim helps to reduce the risk of chipping during use or cleaning, contributing to longer product life and safer laboratory handling.

Quality Assurance

All Westlab glassware undergoes strict quality control procedures. Each item is annealed in conveyor furnaces to eliminate manufacturing stress, enhancing strength and durability. The wall thickness is monitored by qualified testers to ensure compliance with safety and performance standards. Additionally, every piece is subjected to double clarity checks—once after production and again before dispatch—to guarantee optical precision and presentation quality.

Printing & Compliance

Each flask is marked with clear, white enamel printing for easy volume identification. The design conforms to ISO 1773 standards and ensures compatibility with laboratory workflows that require standardised equipment dimensions and performance characteristics.
