Heavy Duty Narrow Mouth Erlenmeyer Flasks, Borosilicate Glass, ASTM E1406, 1L–4L (Sold Each)
The Globe Scientific Globe Glass Heavy Duty Erlenmeyer Flask delivers thick-wall borosilicate construction built for demanding bench work, including reagent mixing, titration, and bulk media preparation. Each narrow-mouth flask conforms to ASTM E1406 dimensional standards, minimizing splash and evaporation during swirling. Reinforced walls resist thermal and mechanical stress across repeated autoclave and heating cycles.

Frequently Asked Questions
Are these Erlenmeyer flasks autoclavable?
Yes. The borosilicate glass withstands standard autoclave cycles at 121°C. Ensure the flask is uncapped or loosely vented to prevent pressure buildup during sterilization.
What does ASTM E1406 compliance mean for these flasks?
ASTM E1406 specifies dimensional and capacity tolerances for laboratory Erlenmeyer flasks. Compliance ensures consistent geometry, fit with standard stoppers, and reliable volumetric accuracy across lots.
Why choose narrow mouth over wide mouth for these volumes?
Narrow-mouth designs reduce evaporation and splashing during vigorous swirling, making them ideal for titrations and solvent mixing. The beaded rim also accepts standard stoppers and foam plugs.
What makes the heavy-duty version different from standard flasks?
Heavy-duty flasks feature thicker walls that improve resistance to mechanical impact and thermal stress. This extends service life under repeated heating, autoclaving, and high-throughput bench handling.
