Iron Powder
Iron filings are very small pieces of iron that look like a light powder. They are very often used in science demonstrations to show the direction of a magnetic field. Since iron is a ferromagnetic material, a magnetic field induces each particle to become a tiny bar magnet.SKU: n/a -
Chemicals
Iso-Butanol
Isobutanol is an organic compound with the formula (CH₃)₂CHCH₂OH. This colorless, flammable liquid with a characteristic smell is mainly used as a solvent. Its isomers, the other butanols, include n-butanol, 2-butanol, and tert-butanol, all of which are important industrially.Formula: C4H10OSKU: n/a -

L-Tryptophan
Tryptophan is an α-amino acid that is used in the biosynthesis of proteins. Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a non-polar aromatic amino acid. It is essential in humans, meaning the body cannot synthesize it; it must be obtained from the diet.Formula: C11H12N2O2SKU: n/a -

Lead Acetate
Lead(II) acetate (Pb(CH3COO)2), also known as lead acetate, lead diacetate, plumbous acetate, sugar of lead,lead sugar, salt of Saturn, or Goulard’s powder, is a white crystalline chemical compound with a sweetish taste. It is made by treating lead(II) oxide with acetic acid. Like otherlead compounds, it is toxic.Formula: Pb(C2H3O2)2SKU: n/a -

Lead Chloride SLR
Lead(II) chloride is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water. Lead(II) chloride is one of the most important lead-based reagents. It also occurs naturally in the form of the mineral cotunnite.Formula: PbCl2SKU: n/a -
Chemicals
Lead Dioxide SLR
Lead(IV) oxide, commonly called lead dioxide, plumbic oxide or anhydrous plumbic acid, is a chemical compound with the formula PbO₂. It is an oxide where lead is in an oxidation state of +4; bond type is predominantly covalent. It is an odorless dark-brown crystalline powder which is nearly insoluble in water.Formula: PbO2SKU: n/a
