【Density calculation method of specific gravity cup】p=(m2-m1)/V, m2= total weight of cup and style (g), m1= empty cup weight (g), V= cup volume (mm) ratio. 【Appearance】304 stainless steel gravity cup adopts cylindrical design, the cup mouth adopts large opening design, easy to pour and clean, one-piece molding, no gap, good inner and outer wall finish, easy to clean. 【Durable】The cup body of the specific gravity cup is 1.2mm thick, thickened material, strong and durable, no bubbles, high test accuracy. Equipped with a tight lid with a small hole in the middle to discharge excess test liquid. 【Material】The specific gravity cup is made of high-quality stainless steel through precision processing, with strong corrosion resistance and oxidation resistance, good inner and outer wall finish, not only a bright appearance, but also a textured interior. 【Note】Before starting, make sure the density cup is clean and dry. After the test, do not use a wire brush, metal scraper or other metal tools to clean.
