Potassium Bromide, lab grade, crystal - 125g.
Mineral oil light (paraffin oil), lab grade
Used as starch indicator, biological stain and chemical reagent. This iodine is laboratory grade and cannot be used for food or medical purposes. 500ml.
Aluminum Metal (20 gauge sheet) - 12" x 12" x .032"
500 grams of Aluminum Metal Shot.
Aluminum metal shot is often used in classrooms for chemistry experiments and demonstrations, such as studying chemical reactions, investigating metal properties, and exploring concepts like density and reactivity. It is commonly used in reaction experiments with acids (like hydrochloric acid) to produce hydrogen gas, allowing students to observe the properties of metal reactivity and gas evolution. Additionally, aluminum shot can be used in physics experiments to study thermal conductivity and heat transfer due to its high thermal conductivity and low density.
The Project Planetarium is ideal for individual study projects. Causes of 2 day and night, seasonal changes, phases of the moon, and planet locations are easily understood. The small planetarium model and solar system chart, 22"x17", may be set to show actual positions of the earth, the moon and planets at any given time. Each set includes planetarium, chart and study guide.
Gives star positions for any date. Shows constellations, stars to 5th magnitude, nebula, Milky Way and the ecliptic. Major stars luminous for outdoor use. Has instructions, planet positions and Zodiac dial on reverse.
Also called glycerin or glycerine, Glycerol is both a colorless and odorless liquid, that is fairly viscous. It is a simple polyol compound, with a triglyceride backbone and 3 hydroxyl groups.
Sodium silicate (water glass) is a clear, colorless liquid. Used in soaps, detergents, adhesives and in waterproofing. Sometimes used to seal small cracks or leaks in the cooling system.
Sodium acetate, lab grade, anhydrous, powder - 500g.
Sodium chloride, lab grade, crystal - 500g
Limewater solution is commonly used for testing the presence of carbon dioxide in gaseous samples in school laboratories, and refining of sugar in a process called carbonatation. 1 liter.
