Glassco Narrow Mouth Erlenmeyer Flask — DIN Graduation
The Glassco narrow mouth Erlenmeyer conical flask with DIN graduation markings is one of the most widely used and versatile items of general laboratory glassware. Manufactured from borosilicate glass with DIN-compliant graduated markings, the narrow mouth design reduces evaporation during mixing and extended incubation periods, and is compatible with standard rubber and plastic stoppers for closed-system or shaker flask applications.
Available in capacities from 25mL to 2000mL with excellent stock availability, these flasks are supplied from Glassco’s European warehouse in the Netherlands for fast and reliable delivery across Ireland.
Key Features
Narrow Mouth Design
The narrow mouth opening significantly reduces evaporation compared to wide-mouth or open-neck flask configurations — making narrow mouth Erlenmeyer flasks the preferred choice for extended incubation, shaking culture growth, and applications where solution volume must be maintained accurately over time.
DIN Graduation Markings
DIN-compliant graduated markings provide reliable volume estimation during solution preparation and mixing, reducing the need for a separate measuring cylinder for routine volume estimation tasks.
Stopper Compatible
The narrow mouth neck is compatible with standard rubber and plastic stoppers for closed-system use in shaker incubators, autoclaving, and storage applications.
Borosilicate Glass
Excellent chemical resistance to acids, bases, and organic solvents, along with good thermal stability for autoclaving and heating applications.

Applications
- Titration — standard conical flask for routine titration procedures in analytical and pharmaceutical QC laboratories
- Microbial culture growth — narrow mouth reduces evaporation during shaker incubation for microbiology workflows
- General solution preparation — mixing, dissolving, and preparing reagents and solutions across routine laboratory workflows
- Academic and teaching laboratories — durable, economical conical flask for educational laboratory use
- Storage and sample handling — temporary storage of samples and reagents with standard stopper
Heavy Duty Option Available
For applications requiring enhanced thermal resistance and mechanical strength — particularly for demanding heating, autoclaving, or aggressive chemical applications — the Erlenmeyer Flask Heavy Duty Borosilicate 3.3 provides additional durability in the same narrow mouth conical form.
