USA Lab S35/20 Round Bottom Spherical Flask – Made in the USA

The USA Lab S35/20 round bottom spherical flask is a classic RBF, manufactured in the United States from one of the highest-rated laboratory glasses available. Built for durability and chemical resistance, this flask is engineered for reliable use in demanding lab environments.

The spherical joint design provides flexibility in the mating angles of connected glassware, which is especially important when working with heavy flasks or extended assemblies. This reduces the risk of breakage caused by bending stress and makes setup and handling more secure.
