Science Education Supplies By Eisco

• PUMICE | Pumice is formed from the frothy lava that a volcanic explosion creates. As the frothy lava cools, it hardens as a light weight rock that is filled with small gas bubbles. Because this rock is so porous and light, it can actually float on water
• GREAT FOR GEOLOGY CLASSROOMS | Perfect for demonstrating the effect of vesicles on rock density, as well as for lesson in identification and classification of igneous rocks. This set of six samples is excellent for group study and examination
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

• Set of 12 cylindrical bars in a variety of materials for identification exercises and exploration of density, mass and volume. Materials included: Hardwood, Softwood, Aluminum, Copper, Brass, Rubber, Nylon, Derlin, PVC, Glass, Acrylic & Teflon. Each cylinder is the same diameter, 0.5\" (12.5mm) but each has a different length. Set includes a wooden storage block
• Excellent for physics classrooms. This set allows learners to explore the relationship between density & mass, and how the density of a substance is constant, even as its mass and volume change
• Set includes a complete manual that describes the basics of density, mass and volume, and instructions for making calculations
• 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 intended to help learners become familiar with the appearance, texture, hardness and density of a variety of common substances, explore volume, density & mass and provide them with quality introductory physics and chemistry concepts

• DIDACTIC MINIATURE SKULL || Skull is made up of 15 individual pieces in various colors for in depth study of the human skull
• HALF NATURAL SIZE || Reduced size, anatomically correct replica. Measures 5.25\" long, 3\" wide and 4\" tall
• REALISTIC DETAILS & TEXTURES || Model features realistic details, textures and bony landmarks - providing an incredible amount of realism for examining human skull bones
• MULTICOLORED, MAGNETIC PIECES || Multicolored pieces for easier identification. Each piece fits together like a puzzle, and is held in place by magnets

• HIGH QUALITY || Rod and base set consisting of a rectangular retort base made of corrosion-resistant, powder-coated pressed steel and a 60cm rod made of steel
• STABILITY || The 8\" long by 5.25\" wide base weighs 3.2lbs, providing superb stability for experiments & setups - The included rod measures 23.6\" tall and is 12mm in diameter
• TAPPED HOLE AND THREADED ROD || Base features a tapped hole, which fits the included rod, and can accommodate other rods with a 10mm x 1.5mm metric thread
• GREAT FOR CLASSROOM & HOME LABORATORIES || The durable and sturdy construction of this set makes it an excellent choice for science classrooms, household laboratories & basic professional laboratory setups
• MANUFACTURED BY EISCO LABS || Eisco Labs proudly manufactures its own products using state-of-the-art equipment, and following the highest standards of quality control. Each product is carefully designed by a team of laboratory professionals and experienced engineers with quality and durability in mind

• Synthetic sheet for repeated pinning
• Adjustable for insects up to 12mm

• 10 strips per pack
• Bimetallic strip attached to wood block (block dimensions: 1.85in X 1.45in X 0.4 in)

• 4 transparent plates to demonstrate magnet fields
• Each plate is 15.3cm x 7.6cm x 0.6cm - 98 chambers

• SCORIA | Scoria forms as spatter from bubbly, mafic lava is thrown into the air and cooled quickly. The crystallization happens so quickly that large air pockets are trapped within the rock, often giving samples a jagged, sharp appearance
• GREAT FOR GEOLOGY CLASSROOMS | A good example of pyroclastic material. Can be used in a variety of igneous classification exercises. This set of six samples is excellent for group study and examination
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY
• INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

• This rectangular plano glass mirror - pack of 10 is designed for physics and educational uses.
• It is approximately 6\" x 4\" and 2mm thick. Note, thickness varies as they are not designed to be consistent in that respect.
• Because of their educational use design, there may be minor imperfections that do not affect physical function.
• Pack of ten

• ANTHRACITE COAL | Anthracite coal is bright and reflective, indicative of the intense heat and pressure required to form it. Anthracite coal often has a favorable purity ratio, containing mostly organic material and relatively few impurities
• GREAT FOR GEOLOGY CLASSROOMS | Ideal for identification & classification exercises. Allows students can get a close look at a material that powers the world. This set of six samples is excellent for group study and examination
