The "Insulation Bolt Type VS II" is a simple type of insulation bolt and nut made from stainless steel, which has excellent corrosion resistance and is designed to prevent electrolysis. Since the sleeve and the outer diameter of the screw are almost the same, there is no need for enlarging the bolt holes in the flange. Because a resin sleeve is used as the insulating material, unlike painting, there is no risk of insulation failure due to peeling or pinholes. Some sizes are kept in stock for immediate delivery. It can be used in general piping, avoiding direct sunlight. 【Features】 - Shuts out corrosion currents caused by fastening bolts between flanges, preventing electrolysis. - Comes with two insulating washers, so the installation direction of the bolt does not matter. - The insulating sleeve and the outer diameter of the screw are almost the same, eliminating the need for enlarging the bolt holes in the flange. - Uses PVC (polyvinyl chloride) for the insulating sleeve, achieving low cost. - The nut (made of stainless steel) is coated with TOM coating, balancing good workability and high durability. *For more details, please refer to the PDF document or feel free to contact us.

The "Disposable Empty Cartridge" is an empty cartridge that can also be used as a mini column for fractionation and as a filter cartridge. It can be used with a wide range of organic solvents in addition to acid/alkaline solutions, and is compatible with commercially available lure adapters and solid phase extraction adapters. Since it is made entirely of resin, there is no concern about adsorption or elution. You can also fill it with your preferred adsorbent to create your original SPE cartridge. 【Features】 ■ Made entirely of resin ■ The body is made of polypropylene, and the frit is made of polyethylene ■ Can be used with a wide range of organic solvents in addition to acid/alkaline solutions ■ Compatible with commercially available lure adapters and solid phase extraction adapters ■ Can be used as a mini column for fractionation and as a filter cartridge *For more details, please refer to the catalog or feel free to contact us.

The "PEEK-made empty column for HPLC" is a column compatible with most organic solvents, acids, and salts used in HPLC. The contact part is made of inert PEEK, so there is no adsorption/denaturation of the target components or rust formation. A pressure test with water confirmed retention at 400 MPa. Additionally, a filling test at 30 MPa has also been confirmed. The inner diameter standard is the same as that of stainless steel columns, with no variation in volume, and handling is the same as that of stainless steel columns. 【Features】 ■ Withstands water pressure up to 400 MPa ■ Passes the filling test at 30 MPa ■ No adsorption/denaturation of the target components or rust formation ■ Compatible with most organic solvents, acids, and salts *For more details, please refer to the catalog or feel free to contact us.

The "TOM Coat" is a dry coating technology that dramatically prevents the phenomenon of "seizing" (galling) that occurs during the tightening of stainless steel bolts and nuts. It has durability that withstands more than six tightenings (under high load) and meets the strict standards of the Japan Water Works Association (JWWA) for preventing seizing in domestic piping. It excels in heat resistance, allowing full utilization of the performance up to the inherent heat resistance temperature of stainless steel. 【Features】 ■ Can be applied to complex shapes ■ Excellent workability for increased efficiency ■ Zero environmental impact, safe and non-toxic ■ Trusted durability recognized by the water and gas industries ■ Resistant to temperatures from -196°C to 800°C *For more details, please refer to the PDF document or feel free to contact us.

When dissimilar metals are joined together in the ground, a potential difference occurs between them, and current flows through the bolts, causing the less noble metal to corrode. By using Tomoe's "Insulated Bolts and Nuts," the areas between flanges and between flanges and bolts/nuts are electrically insulated, preventing electrolytic corrosion. Stainless steel is treated with a dry seizure (galling) prevention coating called "TOM Coat" on the threaded parts of the nuts. Additionally, various steel types can be treated upon request. If you are experiencing issues with galling, not limited to insulated bolts, please consult us. 【Features】 - Uses epoxy resin boards with glass cloth and PTFE sleeves or FEP shrink tubes → Provides high insulation resistance and excellent weather resistance and mechanical strength - Bolt and nut materials include stainless steel, ordinary steel, and high-tensile steel → Can be selected according to application - The outer diameter of the insulating sleeve is almost equal to the outer diameter of the screw → No need to process the bolt hole diameter of the flange - Uses sleeves instead of paint as insulating material → No peeling and no pinhole issues - Made to order, allowing for production in desired dimensions For more details, please contact us or download the catalog.
