Description

USA Made 1 Neck Spherical Round Bottom Flask - 35/20

The USA Made 1 Neck Spherical Round Bottom Flask - 35/20 is a classic round bottom flask designed for laboratory applications requiring a spherical joint connection. Manufactured in the USA from high-quality laboratory glass, this flask combines dependable construction with a practical spherical joining system.

Its spherical joining method allows flexibility in the mating angles of connected glassware, which can be particularly useful when working with heavier flasks or longer glass assemblies. The joint design helps accommodate alignment between connected components and can reduce bending stress that may otherwise place strain on rigid glass connections.

The USA Made 1 Neck Spherical Round Bottom Flask - 35/20 is available in 1000mL / 1L and 2000mL / 2L size options, providing flexibility for different laboratory workflows and glassware configurations. It is well suited for chemistry, pharmaceutical, research, and other laboratory applications requiring round bottom flask construction and spherical joint compatibility.
