DURAN 212162403 Narrow Neck Erlenmeyer Flask 100 mL

DURAN 212162403 Narrow Neck Erlenmeyer Flask 100 mL

The DURAN 212162403 is a classic narrow-neck (DIN) Erlenmeyer flask with 100 mL nominal capacity, made from DURAN® borosilicate glass 3.3. It is constructed to meet DIN/ISO 1773 standards, offering high chemical resistance, low thermal expansion, and excellent durability.

Key features include:

• Approximate printed graduations for rough volume estimation.

• Beaded rim to provide extra strength and reduce risk of chipping.

• Uniform wall thickness for consistent thermal behavior and reduced risk of stress points when heated.

• Retrace (batch) code for traceability and quality control; certificate available online.

• Fully autoclavable.

Specifications

Applications & Use Cases

• Ideal for routine lab tasks: heating, mixing, reagent preparation, and storage where precise measurement isn’t critical.

• Useful in teaching labs, research, quality control: good size for handling small samples.

• The narrow-neck helps reduce splash risk during mixing and limits evaporation.

• Because of its standard compliant build and traceability, suitable where quality documentation matters.

Limitations & Handling Notes

• Graduations are approximate only — do not use this flask when you need precise volumetric measurements (e.g. analytical work).

• Despite durable borosilicate material, it is still glass; avoid impacts and sudden temperature changes (thermal shock).

• Always handle with care when heating, and avoid placing a hot flask directly on cold surfaces
