Flask, Erlenmeyer with Joint

The Flask, Erlenmeyer with Joint by Edulabs is a thick-walled laboratory reaction vessel designed for seamless integration into modular distillation, reflux, and chemical synthesis assemblies. Constructed from high-purity BORO 3.3 Borosilicate Glass, this conical flask features a precision ground-glass socket joint at the neck, eliminating the need for rubber stoppers and ensuring a vapor-tight seal during operation. Its thick-walled body construction offers enhanced mechanical stability and thermal shock durability under elevated temperatures and vacuum conditions. Suitable for organic synthesis, solvent distillation, extraction setups, and vacuum filtration, this flask conforms to standardized ground glass specifications. It provides high chemical resistance against aggressive reagents, acids, and organic solvents. Supplied by Edulabs.

Storage Instructions

  • Store in cushioned storage racks or dedicated glassware cabinets to safeguard the ground joint.

  • Protect ground sockets with plastic caps or tissue wrapping to prevent dust accumulation and joint scoring.

  • Keep stored upright on non-abrasive surfaces to avoid base scratching.

  • Clean grease residue completely from the socket before placing in long-term storage.

  • Store away from mechanical vibration sources and high-traffic aisles.

  • Group by joint socket size and volume capacity for organized laboratory management.

Safety Information

  • Wear appropriate personal safety equipment, including safety glasses, protective gloves, and a lab coat.

  • Inspect the ground socket and glass body carefully for micro-cracks before assembling modular glass apparatus.

  • Apply a thin layer of suitable joint grease or use a PTFE sleeve to prevent joint seizing during thermal exposure.

  • Clamp the flask securely to support stands using cushioned lab clamps during reflux or distillation.

  • Never apply direct flame heating; use appropriate heating mantles, oil baths, or water baths.

  • Ensure adequate venting when heating volatile organic compounds to prevent pressure buildup.

  • Allow the apparatus to cool to room temperature before disassembling ground glass joints.

  • Clean chemical residues from the socket immediately after use to protect the glass surface.

The Flask, Erlenmeyer with Joint engineered by Edulabs is a critical component for specialized organic synthesis, distillation, and reflux setups. Unlike standard Erlenmeyer flasks with beaded rims, this flask features a precision-machined ground glass socket joint integrated directly into its neck. This standardized ground joint enables direct connection to condensers, fractionating columns, addition funnels, and adapter fittings, creating a vapor-tight, leak-proof closed system essential for handling volatile organic compounds and air-sensitive reactions.

The body of the flask is manufactured with thick-walled construction, providing mechanical strength and structural integrity. This robust wall profile ensures high resistance to physical impact and enables the vessel to withstand moderate pressure variations and thermal stress. The broad conical base provides a low center of gravity for stable placement on magnetic stirrers and heating plates, while encouraging continuous fluid circulation during boiling or stirring routines.

Fabricated from high-purity BORO 3.3 Borosilicate Glass, this jointed Erlenmeyer flask exhibits an extraordinarily low coefficient of thermal expansion. This thermal stability makes it ideal for high-temperature refluxing and rapid cooling applications. Furthermore, its chemical durability guarantees non-reactivity when exposed to strong acids, corrosive bases, and aggressive halogenated solvents, preserving sample purity across all procedures.

Offered in an extensive array of volume capacities ranging from 25 ml up to 5000 ml with various standardized socket sizes (such as 14/23, 19/26, 24/29, 29/32, 34/35, and 45/50), the Edulabs Jointed Conical Flask provides compatibility with modular glassware configurations. It serves as a dependable vessel for academic research, pharmaceutical R&D, and industrial chemical testing.

Key Features

  • Made from high-grade BORO 3.3 Borosilicate Glass for superior chemical and thermal resistance.

  • Precision-ground socket joint ensures vapor-tight seals with modular glassware.

  • Thick-walled body construction offers enhanced structural strength and durability.

  • Broad flat conical base ensures stability on hot plates and magnetic stirrers.

  • Eliminates the need for rubber or cork stoppers, preventing rubber leaching.

  • High thermal shock resistance suitable for refluxing, heating, and boiling.

  • Universal chemical compatibility with organic solvents, concentrated acids, and bases.

  • Standardized ground joint sizes allow easy inter-compatibility with condensers and adapters.

  • Ideal for organic synthesis, solvent distillation, and extraction routines.

  • Comprehensive range of capacities from 25 ml to 5000 ml with diverse socket options.
