Flasks, Conical (Erlenmeyer) Narrow Mouth

The Flasks, Conical (Erlenmeyer) Narrow Mouth by Edulabs is a fundamental laboratory glassware item designed for mixing, heating, storing, and liquid measurement tasks. Crafted from high-purity BORO 3.3 Borosilicate Glass, this conical flask features clear volumetric graduation markings and a narrow neck to minimize splashing during agitation. Designed with a heavy-duty reinforced thick rim, it significantly reduces chipping and structural breakage during routine handling and cleaning. Resistant to high thermal shock and aggressive chemical compounds, this flask conforms to strict international laboratory standards, making it suitable for titrations, media preparation, cell culture, and chemical synthesis. Ideal for educational institutions, pharmaceutical testing facilities, and industrial quality control laboratories. Supplied by Edulabs.

Storage Instructions

  • Store in dedicated, padded laboratory cabinets or organize on sturdy shelving racks.

  • Keep stored upright to prevent rim stress and direct side impacts.

  • Avoid nesting glass flasks directly inside one another without protective foam inserts.

  • Maintain in a clean, dry, dust-free environment prior to sterilization or use.

  • Ensure flasks are washed, rinsed with deionized water, and dried thoroughly before storage.

  • Organize inventory according to volume capacity for quick laboratory access.

Safety Information

  • Always wear appropriate personal protective equipment, including safety goggles, heat-resistant gloves, and a lab coat.

  • Inspect the glass base, body, and heavy-duty rim for micro-cracks or scratches before applying direct heat.

  • Place heating mantles or hot plates on flat, stable surfaces with proper temperature monitoring.

  • Avoid boiling liquids in completely sealed narrow-mouth flasks to prevent pressure buildup.

  • Allow heated flasks to cool naturally before washing or placing them on cold countertops.

  • Handle high-capacity flasks (such as 2000 ml to 5000 ml) using both hands or supportive heat pads.

  • Neutralize chemical residues before cleaning to prevent skin exposure.

  • Use appropriate clamps when securing narrow-neck flasks during energetic reactions.

The Flasks, Conical (Erlenmeyer) Narrow Mouth manufactured by Edulabs is a cornerstone piece of scientific apparatus utilized in analytical chemistry, microbiological research, educational instruction, and industrial testing. Invented for versatility, the classical conical Erlenmeyer body profile combines a flat base with a gradually tapering neck. This classic geometry permits energetic swirling and liquid mixing without the risk of liquid spillage, making it the preferred choice for volumetric titrations, chemical reactions, and sample preparation.

The narrow mouth design restricts vapor loss during gentle heating or boiling, making it suitable for volatile solutions and culture media preparation. Integrated along the side wall are bright, durable volumetric graduations that allow technical personnel to estimate liquid volumes quickly during routine workflows. Additionally, the rim of the neck is specifically manufactured with a heavy reinforced thick bead. This reinforced thick rim dramatically enhances mechanical impact resistance, minimizing chipping, cracking, and accidental breakage during washing, clamping, or rubber stopper insertion.

Fabricated from high-grade BORO 3.3 Borosilicate Glass, the Edulabs Conical Flask exhibits an exceptionally low coefficient of thermal expansion. This property grants superior thermal shock resistance, enabling the vessel to transition safely between rapid heating cycles and autoclave sterilization routines. Furthermore, its chemical durability ensures near-universal resistance against concentrated acids, alkaline solutions, and organic solvents, preventing chemical leaching into sensitive biological cultures or chemical reagents.

Engineered to fulfill rigorous international laboratory requirements, the Edulabs Narrow Mouth Erlenmeyer Flask ranges in capacity from 25 ml up to 5000 ml. Whether employed in school chemistry labs or advanced biotechnology research centers, Edulabs provides reliable, high-durability glassware built for safety and long-term serviceability.
