Erlenmeyer Flasks From USA Lab
Trusted, Versatile Glassware for Mixing, Heating, and Storage
Erlenmeyer flasks are a staple in every lab, offering reliable performance for mixing, heating, and handling liquids. USA Lab's flasks are made from durable borosilicate glass, providing excellent resistance to heat, shock, and chemical corrosion. Whether you're preparing solutions, collecting samples, or conducting reactions, these flasks deliver precision and durability you can count on.
Made for Daily Lab Work
Borosilicate 3.3 Glass
Resists high heat, thermal shock, and chemical corrosion for dependable daily use that holds up during repeated heating, cooling, and solvent exposure.
Wide Base for Stability
Reduces tipping risk and allows uniform heating across the bottom surface, whether you're using a hot plate, heating mantle, or water bath.
Tapered Neck Design
Minimizes evaporation and helps control splashing during mixing or boiling while still allowing easy access for stoppers, thermometers, or adapters.
Ground-Glass 24/40 Joint Options
Compatible with condensers, adapters, and vacuum setups for a secure, leak-free seal across standard distillation, reflux, and extraction assemblies.
