The outer diameters of the double-walled glass tubes, 7mm and 8mm, are available for sale in successor materials.
Borosilicate glass tubes have a high expansion coefficient and can be processed with general burners, making them commonly used in school experiments. However, Japanese manufacturers have already discontinued production, and they are currently available only while supplies last. Nevertheless, for the two most commonly used sizes, 7mm and 8mm in outer diameter (both with a wall thickness of 1mm), imported products have become available for future supply.

Company information
In 1907, we established a private business, a scientific glass processing plant, in the Kita Ward of Osaka City. Subsequently, in 1957, we reorganized into a corporation in line with the development of the business, becoming what is now Fuji Rika Kogyo Co., Ltd. Our main operations have been the production of glass products and the sale of scientific instrument manufacturer products. For over 100 years, we have steadily progressed alongside scientific glass and scientific instruments. However, we will cease operations at the end of June 2024 and will begin operations in July under MIZUKEN Co., Ltd. (formerly the Comprehensive Water Research Institute).
