塩谷硝子 List of Products and Services

"Sulfur processing" is a special treatment that excels in suppressing metal elution. A solution of ammonium sulfate is added to vials that have completed primary processing, and during subsequent annealing, it primarily reacts with alkali metals. By selectively reacting and extracting the alkali components on the inner surface of the vial, low metal elution is achieved. The treated vials have a surface layer rich in silica components, which helps reduce the elution of alkali metals. 【Features】 ■ Inject ammonium sulfate solution into vials that have completed primary processing ■ React primarily with alkali metals during annealing ■ Selectively react and extract alkali components on the inner surface of the vial to achieve low metal elution ■ Can be used safely in formulations where basic pH shifts and reactions with alkali metals are a concern *For more details, please refer to the PDF document or feel free to contact us.

"Silicoat processing" is a metal ion suppression technology that applies thin film formation techniques. By forming a silicon dioxide (SiO2) thin film on the inner surface of glass containers, it effectively suppresses the leaching of metals derived from borosilicate glass. This enhances the stability of formulations, making it safe to use for formulations that require pH control. Additionally, due to the effect of the thin film, the formulation no longer comes into direct contact with the inner surface of the glass, which is expected to help suppress flaking (interlayer delamination). 【Features】 - Heat treatment is performed while introducing silicoat gas into the inner surface of the glass container. - A thin film of silicon dioxide (SiO2) is formed. - It utilizes thin film formation technology. - Since the film is formed through a chemical reaction, it is a significant technology for preventing film separation (delamination). *For more details, please refer to the PDF document or feel free to contact us.*

Our company manufactures pharmaceutical glass containers, specifically "cartridges/syringes." The "cartridge" production facility can produce up to 400,000 units per day, meeting the needs for pharmaceutical containers. Since these containers come into direct contact with pharmaceuticals, they are packaged using an automated packing system that does not involve human handling. The "syringe" is supported in many medical settings due to its diverse tip shapes, high inner diameter precision, and ability to accommodate individual needs. 【Features of the Cartridge】 - Supplies approximately 70% of the domestic dental cartridge market share. - Packaged using an automated packing system that does not involve human handling. - Even in large-scale production systems, clean manufacturing is conducted by a small number of managers. - In addition to high-precision and high-speed inspections using camera judgment, visual inspections by skilled inspectors are also performed. *For more details, please refer to the PDF document or feel free to contact us.

Introducing Shioya Glass's "Low Leaching Glass Vials." Thanks to a groundbreaking new technology for cleaning and treating the inner surface of vials, we have successfully reduced the leaching of metal ions significantly compared to current three-pronged vials in long-term stability tests, allowing us to supply stable products with minimal variation within the usual lead time. Furthermore, this technology is also effective in suppressing protein adsorption and delamination. 【Available Vials】 　■ SE Vials (Stable Elution) 　■ LE Vials (Lower Elution) 　■ LE+ Vials (Lower Elution Plus) *For more details, please refer to the PDF document or feel free to contact us.
