Round-Bottom Flask — 1000mL, 24/40 Ground Glass Joint, Borosilicate

The round-bottom flask is the signature vessel of organic chemistry — its spherical geometry distributes mechanical stress evenly, making it the only safe choice for reflux, distillation, and vacuum applications.

The 24/40 ground glass joint is the universal standard fitting in organic chemistry apparatus: it mates directly with condensers, distillation heads, Dean-Stark traps, and rotary evaporator adapters without clamps. Borosilicate 3.3 glass maintains structural integrity under full vacuum (-1 atm) and resists all organic solvents, including halogenated species, acetone, and DMSO.

• 1000mL volume; 24/40 standard taper ground glass joint
• Borosilicate 3.3 — vacuum-rated, solvent resistant, autoclavable
• Compatible with all standard 24/40 glassware (condensers, heads)
• Uniform wall thickness; 200mm neck length
