A History of Hotpack

Hotpack was founded in 1908 in Philadelphia as the Electric Hotpack Co., Inc., originally manufacturing laboratory heating devices. At a time when scientists lacked reliable, consistent temperature control for their experiments, Hotpack delivered precision heating equipment that brought reproducibility to laboratory work.

Over the decades, Hotpack expanded into ovens, incubators, and environmental chambers, eventually joining the SP family as part of the original portfolio of brands. Today, Hotpack continues its legacy of quality and durability, specializing in glassware washers and reach-in stability chambers trusted by laboratories around the world.

Our century of expertise and validated technology help keep your lab clean, stable, and compliant.
