Never heat a liquid in a closed container Stoppers are OK if there is no heat No stoppers More than one test tube can be heated at a time.

H2OH2O Acid Pour acid into water.

Hot plate Hot water bath – used for heating volatile (easily flammable) liquids. Ø No volatile liquids With a Bunsen burner

Scalpel hold like a pencil. Cut away from yourself and others.

Culture only nonpathogen bacteria. Nonpathogen means NOT disease causing All cultures must be disposed of by the teacher. Bacteria cultures

Pipette –precise measurement for tiny amounts Dropper pipette – Measurement not precise Micropipette

Graduated cylinder – measures volume in milliliters, ml. Meniscus – Curve of liquid. Measure from the bottom of the curve. Graduated Cylinder
