Our Own Kilns Capable of Melting Sand to Produce Heat-Resistant Glass

Ensuring a Stable Supply, We Accommodate OEM and Custom Orders

HARIO Science is a company specializing in laboratory glassware within the HARIO Group, a heat-resistant glass manufacturer founded in 1921.

Heat-resistant glass is indispensable in experiment and analysis sites. There are only a handful of manufacturers worldwide with integrated production systems, from melting the raw sand to final product manufacturing, all within their own group and with their own kilns.

At HARIO Science, backed by the HARIO Group’s stable supply capabilities and unique technological foundation, we reliably deliver high-quality heat-resistant glass to our customers. Furthermore, we can flexibly accommodate OEM orders in shapes tailored to laboratory needs, as well as detailed custom manufacturing.

Heat-Resistant Glass Crafted with a Commitment to Pure Materials

Even as resin products have become widespread in recent years, the value of glass, offering superior heat resistance, chemical resistance, and hygiene, remains unchanged. HARIO Science is one of the few companies in the world to own heat-resistant glass manufacturing kilns within its own group, and we provide high-quality products using technology cultivated over many years.

We use only carefully selected, pure materials. Furthermore, we use natural salt defoamers and lead-free printing, ensuring the utmost consideration for safety. High dimensional precision achieved through molds and functional spouts contribute to improved reproducibility in experiments and analyses, as well as reduced contamination risks. From mass production to small-batch custom orders, we deliver optimal glass solutions as a trusted partner supporting the evolution of experiment environments.

Flexible Support from Small-Batch to Mass Production

Efficiency, high-precision, and consistent quality are essential in experiment and analysis sites. We operate two manufacturing lines: “machine forming,” which ensures uniform quality and productivity, and “hand forming,” which meets our customers’ specific requirements.

We specialize not only in standard products but also in “custom response” to achieve complex shapes and specifications, drawing on the expertise we have cultivated over many years. Furthermore, we provide high-quality glass products with reduced contamination risks under a rigorous quality control system. As a partner supporting research and development sites, we propose glass containers with optimal shapes and functionality, from mass production to the prototype stage. We help ensure your new discoveries and challenges are a success with our consistent technological capabilities and flexible manufacturing system.
