Lull-A-Fly™
triethylamine with a scent added
FB1438 vial $11.95
HAZARD ALERT: Flammable liquid; moderately toxic by ingestion and
inhalation; use only in a well-ventilated area; corrosive to eyes or skin.
Storage: Organic #2
Disposal: #5
Shelf Life: Indefinite
Soluble: Alcohol and water.
Color and Odor: Colorless liquid with licorice odor.
Technical Note: The scent is added to reduce the undesirable ammonia
odor. This substance does not act to anesthetize Drosophila as quickly or
easily as ether. If the instructions are followed carefully, it is possible to
perfect the anesthetic process. If you have tried other ether substitutes and
did not like them, you will not like Lull-A-Fly™ since the material is the same
(i.e., triethylamine). However, Lull-A-Fly is a much safer substance than ether.

How to Use a Fire Extinguisher
It seems so simple! Pull the pin, point the extinguisher nozzle, and press
the lever that releases the extinguisher’s contents. If you have never used
a hand-held extinguisher,
the time to learn is before an emergency occurs.
Ask your local fire protection professionals for a lesson in fire extinguisher
use. How to use a handheld extinguisher
makes a great in-service session.
Your local fire department
will be glad to help.
