Sodium
 HAZARD ALERT: A flammable, corrosive solid; dangerous when exposed to heat or flame; dangerous by reaction with moist air, water or any oxidizer. Spontaneously flammable when heated in air; reacts violently with water, producing very dangerous hydrogen gas and a solution of corrosive sodium hydroxide.
Storage: Inorganic #1 under dry mineral oil and inside a Flinn Saf-StorTM Can. Sodium metal must always be stored under dry mineral oil to prevent contact with moist air.
Disposal: #3
Shelf Life: Good, if stored safely.
Color and Odor: New material: metallic gray. Old mate-
rial: white gray. Metal itself is odorless but is usually stored under an oil or kerosene, either of which may have an odor.
CAS No. 7440-23-5
*These two packages contain small, pre-cut pieces of sodium for demonstrations.
Technical Note: As you handle sodium be particularly attentive to the use of dry utensils and an entirely dry work surface. Use all appropriate personal safety apparel, i.e., gloves, apron, face shield, etc. Sodium would be the better choice to demonstrate the charac- teristics of an alkali metal than potassium. Potassium may develop potentially explosive peroxides.
Sodium Acetate
 HAZARD ALERT: Skin, eye and respiratory irritant. LD50 3530 mg/kg. Storage: Inorganic #2
Disposal: #26a
Shelf Life: Fair to poor; substance efflorescent.
Soluble: Water; slightly in alcohol.
Color and Odor: White solid with faint vinegar odor. CAS No. 6131-90-4

Microscopes and
Stereoscopes
Flinn Scientific developed this line of microscopes to give you all the most popular features at every price point. What used to be superior is now standard with Flinn microscopes and stereoscopes!
• All Flinn microscopes have achromatic eyepieces and objective lenses and
condensers to increase resolution.
• 40X and 100X objectives all retract to prevent damage to the slide or objective.
• LED illumination is standard and most of the scopes are rechargeable.
• A digital option is available for both the Economy and Advanced lines.
Flinn Stereoscopes
Equip your students with high-quality Flinn microscopes and stereoscopes!
