DURAN 212176303 Narrow-Neck Erlenmeyer Flask 2000 mL
Detailed Description
The DURAN 212176303 is a 2,000 mL Super Duty Erlenmeyer flask with a narrow-neck design, manufactured from borosilicate glass 3.3 (also called Boro 3.3). It features a reinforced rim for improved mechanical strength and higher impact resistance, making it more durable under frequent handling and rough lab conditions. The flask is graduated with a visible white scale for approximate volume estimation. A fired-on white ceramic label field provides a durable area for marking, which withstands repeated cleaning and sterilization. The flask is autoclavable and designed for demanding lab applications such as heating, mixing, dilution, and measuring liquids.
Key Specifications
| Parameter | Value |
|---|---|
| Nominal Capacity | 2,000 mL |
| Material | Borosilicate Glass 3.3 (“Super Duty”) |
| Reinforced Rim | Yes — for improved mechanical and impact strength |
| Graduation Scale | White, easy-to-read approximate graduations for volume estimation |
| Label Field | Fired-on white ceramic for durability |
| Dimensions (Neck × Body Ø × Height) | ≈ φ50 mm neck × φ166 mm body × 280 mm height |
| Autoclavable | Yes — safe for steam sterilization (about 121 °C) |
| Standards / Use-Case Warnings | To avoid breakage from thermal stress, uniform and slow heating recommended; suitable for general lab mixing, measuring, and heating applications |
Applications & Advantages
Suitable for mixing, heating, diluting, and storing large volumes (2 L) of liquids.
Because of its Super Duty design, it has extended durability: less risk of breakage, better for frequent cleaning, handling, or rough usage.
The narrow neck helps reduce splashing and evaporation, useful when working with volatile or reactive liquids.
The long height and large body give enough volume capacity while maintaining safety via reinforced rim and stable design.
Limitations & Handling Notes
The graduations are approximate only — not suitable for high-precision volumetric analysis (e.g. analytical titration).
Even with reinforced rim, the flask remains glass; avoid impact, thermal shock, and extreme temperature changes.
Given its size and height (~280 mm), handling when full or hot requires care (use both hands, stable surface).
Uniform heating is important to avoid stress — avoid placing directly on intense flame or cold surfaces when hot.
