DURAN 212175401 Narrow Neck Erlenmeyer Flask 1000 mL

DURAN 212175401 Narrow Neck Erlenmeyer Flask 1000 mL

The DURAN 212175401 is a Super Duty Erlenmeyer flask with a 1,000 mL capacity, designed with a narrow neck and manufactured from borosilicate glass 3.3. Built for demanding laboratory conditions, it features a reinforced rim to increase mechanical strength and impact resistance. The flask has an easy-to-read white graduation scale for approximate volume estimation, along with a fired-on white ceramic label field that ensures durable sample identification even after repeated washing and sterilization. Fully autoclavable (~121 °C), this flask is ideal for laboratories requiring strong, long-lasting glassware.

Key Specifications

Features & Benefits

• High strength & durability: Super Duty construction with reinforced rim makes it suitable for intensive use, frequent washing, and higher risk of impact.

• Approximate measurements: Printed graduations enable quick volume estimation when high precision is not required.

• Durable labeling: Fired-on ceramic label field remains legible after repeated cleaning and autoclaving.

• Safety & sterilization: Autoclavable design combined with borosilicate glass 3.3 ensures resistance to high temperatures and chemical corrosion.

Limitations & Notes

• Graduations are approximate only and not suitable for precise analytical work such as titrations.

• Despite its reinforced design, it remains glass and can still break if dropped or exposed to sudden thermal shock.

• With its large 1,000 mL volume, the flask can be heavy when full and must be handled carefully, particularly with hot liquids.
