Erlenmeyer Flask Set — Borosilicate Glass, 100/250/500mL, Wide-Mouth

The conical geometry of the Erlenmeyer flask was designed for one reason: swirling without spillage — making it the universal vessel for titrations, cell culture, and reaction monitoring.

The wide, flat base provides stability during magnetic stirring; the tapered neck reduces evaporation and accepts standard rubber stoppers. Borosilicate 3.3 construction handles pH extremes from concentrated HCl to 10M NaOH without glass attack, and withstands autoclave sterilization at 121°C repeatedly. Narrow-mouth design maintains sample integrity during extended heating.

• Set of 3: 100mL, 250mL, 500mL — borosilicate 3.3 glass
• Narrow mouth accepts standard #6, #7, #8 rubber stoppers
• Calibrated graduation marks ±5% ISO Class B
• Autoclave compatible; uniform wall thickness for even heating
