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.
There are flat-bottom flasks available in sizes ranging from 200ml to 5L. H-32: HARIO-32 is a borosilicate glass with a low thermal expansion coefficient, completed after years of research. It is a glass that meets the "Borosilicate Glass-1" standard specified by JIS, excelling in 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 has high heat resistance, capable of withstanding a temperature shock of 250 degrees with minimal expansion and contraction from heating and rapid cooling.
