5 piece specific gravity metal cylinder set. Each cylinder features a top hook. Set includes Copper, Iron, Aluminum & Zinc. Each cylinder has the same 0.5" (12.5mm) diameter and mass but are various lengths. Since these cylinders are equipped with hooks, they can be easily lifted from boiling water. Additionally, the hooks allow each cylinder to be easily massed using a spring scale (scale not included). Excellent for physics classrooms. Density metals have a wide range of educational applications for all grade levels, including density investigation, specific heat and specific gravity exploration. Set includes a complete instruction manual that gives a background on density, specific gravity & specific heat and includes inquiry based student activities with capture sheets.
Due to the nature of raw metals, some oxidation or corrosion due to humidity and storage may occur. Simply scuff any oxidation off to make the item look brand new again. These density metals are designed to be used in an educational setting and are not fabricated using ultra high precision machining. Expect tolerances in the +/- 5% range of any stated dimensions (although they are generally much tighter).
The Eisco Labs Density Investigation series is designed to help students identify and figure out mass, understand the relationship between mass, volume & density, to understand specific heat and specific gravity and provide them with quality introductory physics and chemistry concepts.
Started over 50 years ago as a small, family-owned manufacturing company, Eisco now produces over 6,500 product lines for the science education and scientific research markets. They have headquarters in both India and the US, and serve hundreds of distributors around the world.
Their core products include glassware, physics apparatus, biology models & equipment, and chemistry lab supplies. Products are designed by a team of laboratory professionals and engineers with quality and durability in mind.
