A heat-resistant glass manufacturer with production facilities in the country. Do you have any issues with scientific glass?
HARIO has been manufacturing heat-resistant glass for scientific and industrial use since 1921. We have a furnace for "α32 heat-resistant glass" in Japan and also produce hand-blown (handcrafted) items. The skills of our hand-blowing artisans have made it possible to create the first "Kamiokande" (a particle observation device) and glass musical instruments. HARIO brand scientific glass is a product backed by a solid history and reliable materials. This comprehensive catalog introduces heat-resistant glass scientific products (finished products and semi-finished products). For more details, please contact us or download the catalog.

Applications/Examples of results
There is a long history of use in national public offices, research institutes, schools, and manufacturing companies. When heating, please avoid local overheating. If you are heating substances with low boiling points or flammable materials, please use a water bath. When handling heated glass, always use heat-resistant gloves or specialized tongs to prevent burns. When used under reduced pressure, round-bottom flasks, pear-shaped flasks, and Kjeldahl flasks are used for chemical reaction tests and reduced pressure distillation tests. However, please check for any "scratches," "distortions," or "uneven thickness" before use. Avoid using flat-bottom flasks or triangular flasks, as they have weaker structural strength.
