This specialized formulation features an ultra-high concentration of 200 parts per million, consisting of 99.99 percent pure gold nanoparticles meticulously suspended in pharmaceutical-grade, pure water. Engineered for advanced biological labeling and scientific applications, this advanced colloidal suspension maintains an extremely fine nanoparticle size of under 3 nanometers to ensure optimal performance in precise experimental environments. Free of chemical preservatives and stabilizers, the liquid exhibits a characteristic very dark red hue, which serves as an indicator of colloidal stability. Each 250 milliliter volume is securely packaged in a clear, bisphenol-A-free plastic bottle complemented by a phenolic cap to preserve integrity during transit. To ensure lasting efficacy, the formulation must be strictly protected from prolonged freezing temperatures and direct sunlight, as freezing causes the suspension to collapse and the nanoparticles to settle. Trust Rudra Retails to source your specialized analytical chemicals directly from the United States, bringing elite scientific materials straight to your laboratory.\u003c\/p\u003e","brand":"Sirius Metals","offers":[{"title":"Default Title","offer_id":52001918976317,"sku":"Rudra-B013FDAYQI","price":10539.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/7602\/2333\/files\/padded_1772509453.jpg?v=1784457063","url":"https:\/\/rudraretails.com\/products\/sirius-metals-true-colloidal-gold-200-ppm-250-ml","provider":"Rudra Retails","version":"1.0","type":"link"}
