This FUJIFILM Wako catalog showcases a comprehensive array of high-purity and certified reagents specifically designed for analytical chemistry, ensuring precision and reliability across diverse applications. The extensive product range is categorized to meet various laboratory demands. The **Reagents for Titration** section features prepared reagents for volumetric analysis, certified reference materials (CRMs) under ASNITE and JCSS accreditation for national metrology traceability, and a wide selection of indicators compliant with JIS K8001. It also includes specialized reagents for potentiometric, colloidal, and non-aqueous titrations, as well as Karl Fischer reagents for accurate moisture determination, utilizing components like iodine and sulfur dioxide. For **Metal Analysis**, the catalog offers reagents for atomic absorption spectrochemical analysis, providing high-sensitivity and selective detection of trace metals. This includes ultra-low impurity pretreatment reagents, JCSS-certified standard metal solutions, multielement standard solutions for ICP analysis, and reagents for detecting poisonous metals at ppb levels. The **Highly-Pure Solvents / Acids** category highlights Super Special Grade (S.S.G.) reagents, ultratrace analysis reagents with guaranteed ppt-level metallic impurities (packaged in PFA containers and double plastic bags for cleanroom use, with ICP-MS/FL-AAS analysis reports), and electronic industry-grade reagents with minimized particles. The Infinity Pure Series provides ultra-purified, small-volume reagents ideal for sensitive biochemical applications like gene engineering. Additionally, the catalog lists **Reagents for NMR**, including shift reagents to enhance signal separation and internal standard reference materials for accurate peak position determination, alongside various high-quality NMR test tubes. Specialized offerings extend to **Wetting Tension Test Mixtures** for plastic films (conforming to JIS K6768), **CSK Standard Solutions** for nutrient salt analysis in seawater, and **NMIJ Certified Reference Materials (NMIJ CRM)**, which are produced according to ISO Guide 34/35, ensuring metrological traceability and certified values with uncertainties. All products are strictly for laboratory research use.
