Description
Innovating Science Synthesis of Rayon Kit In this polymer chemistry experiment, recyclable paper (newspaper etc.) is dissolved in a solution of Ammonium Hydroxide and Cupric Sulfate before being added to a sulfuric acid solution with an eye dropper, forming blue strands. Students learn that Cuprammonium Rayon is an example of a regenerated cellulose by observing a natural rayon dissolved into an aqueous solution. For Laboratory Use Only. Not for drug, food or household use. Keep out of reach of children. For more information, refer to the Safety Data Sheet. Product Details Brand Innovating Science Manufacturer Innovating Science Product Type Science Lab Education Curriculum Support Mpn IS7001 Exciting polymer demonstration in which students synthesize rayon using recycled paper! Cuprammonium Rayon is produced by dissolving natural cellulose Blue Rayon strands are produced in aqueous solution, as Rayon is insoluble in water Instructions and Safety Data Sheet included Check out my other items. - Powered by

Arrived on time and items were exactly as advertised. The package was double boxed, and although the outer box was in pristine condition and marked as being fragile, there was minor damage to the inner box that did penetrate the cardboard. Fortunately, the glass items themselves were completely undamaged. Recommend inspecting any fragile items with the postal carrier present in the case that documentation is required. Otherwise, an excellent transaction!

Extremely happy with the box of rocks. I ordered the Moh's hardness kit, but they sent the Sedimentary box. I showed the seller a picture of the box. The seller (hbarsci) apologized and quickly sent the correct box without any argument or dispute. I got two for the price of one😍. Thank you 100%.
