DURAN 212166808 Narrow Neck Erlenmeyer Flask 3000 mL

DURAN 212166808 Narrow Neck Erlenmeyer Flask 3000 mL

The DURAN 212166808 is a 3,000 mL narrow-neck Erlenmeyer (conical) flask crafted from DURAN® borosilicate glass 3.3. It is specifically engineered for large-volume laboratory applications that demand exceptional chemical resistance, thermal durability, and long-term reliability. Featuring a conical body with a flat base, this flask ensures stable placement on heating surfaces while supporting uniform heat distribution. The narrow-neck design minimizes evaporation, prevents splashing during mixing, and improves handling of liquid samples. It is engineered for large-volume laboratory tasks that require chemical stability, thermal resistance, and durable construction,

Applications & Use-Cases

• Preparation of large volumes of reagents, buffers, or culture media

• Heating, mixing, or swirling large liquid quantities in chemistry, biology, or industrial labs

• Useful in labs that require periodic sterilization of large glassware

Limitations & Handling Notes

• Graduations are approximate; do not rely on this flask for high-precision volumetric work

• Non-sterile on delivery; sterilization needed before use in aseptic or culture work

• Glass is still fragile: avoid impact, thermal shock (rapid heating or cooling), and ensure proper support when hot and full

• Because it is large (3 L), handling requires care — ensure stable surfaces, avoid overfilling, and use appropriate gloves or supports
