DURAN 212177308 Narrow Neck Erlenmeyer Flask 5000 mL

DURAN 212177308 Narrow Neck Erlenmeyer Flask 5000 mL

The DURAN 212177308 is a 5,000 mL Super Duty narrow-neck Erlenmeyer flask, made from borosilicate glass 3.3. It’s part of the Super Duty line, meaning it has extra mechanical strength and built-to-last features. The rim is reinforced to improve impact resistance and reduce risk of breakage during handling, cleaning, or frequent use. It also has a graduated white scale to estimate liquid volume, plus a fired-on white ceramic label field for sample identification that endures repeated washing and sterilization.

Because of its large size, care should be taken with heating: uniform, gradual heating is advised to avoid thermal stress and cracking. It is autoclavable and fits applications involving mixing, heating, solution preparation, or storage of large volumes.

Key Specifications

Applications & Benefits

• Suitable for laboratory tasks involving large volume liquids (5 L), such as mixing, heating, reagent prep, or bulk handling.

• Durable design reduces risk of accidental breakage, improving safety and lowering replacement cost over time.

• Narrow neck helps to reduce spillage, evaporation, or contamination.

• Ceramic label field allows persistent marking even after many sterilization cycles.

Limitations & Handling Notes

• Graduations are approximate only — not suitable when high precision is required (e.g. analytical or volumetric measurements).

• Large capacity and height make it heavy when full; use care in handling, especially when moving or heating.

• Even though the rim is reinforced, glass remains fragile under sharp impacts or thermal shock (sudden changes in temperature).
