Sanwa Tsusho CO., LTD.

Sanwa Tsusho Company Limited was established in 1974. Since then we have been supplying high-quality instruments, units, components and materials to the fields of science, chemistry, analysis, clinical testing, and research and development.

Area of our customers ranges worldwide, mostly Europe and North America besides Japan, but also in area of East Asia, South Asia, and Middle East. Our products are used in universities, government research institutes, corporate laboratories, development, manufacturing, and contract design and manufacturing divisions.

Highly appreciated on consistent quality level, our products have been repetitively purchased over the years.

We would keep doing our best to propose solutions most suitable to realize individual goal of our customers and to supply products which purchase would result at additional value for our customers.

Typical products Sanwa Tsusho Company Limited has supplied in the fields of science, chemistry, analysis, clinical testing, research and development are (1) pumps, (2) valves, (3) filters, (4) degassers, (5) recorders, (6) scientific instruments, (7) OEM modules to be built in instruments, (8) precision balls, (9) sensors, (10) metal components, (11) plastic tubing and (12) ceramic resistors for heavy electric industry, power plant and communication.

(A) Our pumps with a wide variety have covered from liquid feeding to gas feeding, coping with various media including surfactant, other high viscous liquids, hydrochloric acid, sulfuric acid, and versatile requirements even for super micro volume dispensing or high reproducibility,

The pumps would take an essential role in academic, research, analysis, development, manufacturing, and reuse of resources such as urban mines.

(B) Filters we supply have a 90 % void ratio, minimizing filtration resistance, and reducing time for filtering process,

The filter differs in construction from the conventional one. Pore size gets more uniform. Inner volume is meniscus.

Filters are available with pore size down to 0.2 um.

Ideal for applications such as Gel Permeation Chromatography (GPC), Supercritical Fluid Chromatography (SFC), Light Scattering Detection (LSD), and Polymer filtration, among many.

(C) Our degassers, stand-alone model, have been used in laboratories around the world since early days when necessity of on-line degassing was recognized in HPLC.

Years later, demands in market moved. Degassing function became a de facto standard in HPLC systems. Our degasser OEM modules have been adopted by numbers of HPLC system manufacturers as well-established products.

(D) We also have ceramic resistors in our sales line.

These are ideal resistors for high-voltage and high-electric power such as snubber circuit in gate turn-off (GTO) thyristor and braking or discharging resistors for lighting surge generators.

The shape varies from small rods to discs, and doughnuts.

Water-cooled versions are also available, direct or indirect.

The sintered ceramic resistors have high durability and reliability without disconnection and inductivity even in challenging environment and application where reliability is one of the most important factors.

Withstanding against high-voltage and high-electric power, the resistors are, yet, of space-saving configuration.

The characteristics are stable thermally and chemically.

Usage in water or oil is possible.

We would continue our utmost efforts to be of service to you with proposals and flexible idea based on long year experience.
