The minimum injection volume of the modular syringe driver is 0.015 mL, achieving very high measurement accuracy.
The sample is titrated with hydrochloric acid, and measurements are taken until the colorimetric endpoint corresponding to the specified pH is reached. The alkalinity of phenolphthalein is measured by titrating to pH 8.3, which is confirmed by the color change of the phenolphthalein indicator. This value indicates the total amount of hydroxide ions (OH⁻) present in the sample, as well as half the amount of carbonate ions (CO₃²⁻).

Company information
Sunny Trading has consistently specialized in the import and sales of automatic control and labor-saving equipment since its establishment in 1961, actively introducing the latest high-performance machinery and equipment from Europe and the United States to the domestic market. The components for production machinery that we handle are widely adopted in industries such as machinery, electrical, and chemical, and we take pride in our extensive delivery track record to national government agencies, universities, research institutions, and the aerospace industry. The delivered parts are incorporated into machines to complete large production facilities, but confirming the compatibility of the products is essential for this process. We always strive to provide appropriate products by investing technical know-how and time for specification confirmation between overseas manufacturers and our customers. Additionally, we take responsibility for follow-up services, including on-site inspections of delivered products and maintenance. Unlike general trading companies that simply import and sell goods, we pride ourselves on being a trading company with engineering capabilities. Products are commercialized as machines by manufacturers, and they are actively utilized in core industries such as semiconductors, steel, shipbuilding, aerospace, packaging, logistics, and chemicals.
