Flat-bottom flask made of heat-resistant glass
The mouth is designed with a durable, thick rim. It can be widely used for measuring, stirring, and culturing.
The flat-bottom flask is available in sizes ranging from 200ml to 5L. H-32: HARIO-32 is a borosilicate glass with a low expansion coefficient, completed after years of research. It is a glass that meets the "Borosilicate Glass-1" standard specified by JIS, known for its excellent chemical durability and heat resistance. It does not contain any heavy metals such as lead, zinc, or cadmium, nor does it use sulfurous acid or antimony, which are commonly used as bubble agents in regular glass. Due to its small expansion coefficient, it experiences minimal expansion and contraction from heating and rapid cooling, making it a glass material with high heat resistance that can withstand a temperature shock of 250 degrees.
