HARIO Science Official Online Store OPEN! Heat-resistant glass scientific products

This is a beaker with excellent heat resistance and chemical properties. The flared opening makes it easy to hold and reduces the likelihood of liquid dripping from the spout.

There are products ranging from 10ml to 10L beakers. 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, exhibiting excellent chemical durability and heat resistance. It does not contain any heavy metals such as lead, zinc, and cadmium, nor does it use sulfurous acid or antimony, which are commonly used as foam agents in regular glass. Due to its low 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.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

SPACECOOL Inc., which researches, develops, and sells the radiation cooling material "SPACECOOL" that releases heat into space to achieve zero-energy cooling, will exhibit at the "Jumbo Surprise Exhibition," a comprehensive trade fair for electrical materials and housing equipment, held at Tokyo Big Sight from April 17 (Friday) to April 18 (Saturday), 2026, and at Intex Osaka from April 24 (Friday) to April 25 (Saturday), 2026. This material is a new technology that enables zero-energy cooling by converting heat into infrared radiation and releasing it into space, without using any external power. By implementing it in outdoor air conditioning units and outdoor electrical equipment, it helps suppress internal temperature rises, contributing to stable operation of devices and reduction of air conditioning energy consumption, and is being recognized as a new carbon-neutral technology. Its energy-saving performance has been acknowledged, and this material received the 2025 Energy Conservation Award. When you visit the venue, please stop by our booth. Our booth number is 972 (common for both Tokyo and Osaka). We will continue to work towards expanding the social implementation of SPACECOOL to contribute to the stable operation of outdoor equipment and air conditioning units, as well as to reduce air conditioning energy consumption and CO2 emissions.
