Safety Purchase Consideration: Buy and store only small package sizes
and small quantities. For safety reasons, Flinn offers larger sizes of ammonium
hydroxide and other hazardous substances in PVC-coated bottles. We have
attempted to price the products in these safer containers as low as possible.
*Ammonium hydroxide is exactly as described under catalog number A0052
but in a PVC-coated bottle. In the event of breakage, base and glass shards
are safely retained in a PVC outer envelope. The PVC-coated bottle is a safer
package for science teachers.

Flinn Bases:
The Safer Choice
Ammonium hydroxide is an essential part of any chemical laboratory, but is also one of the more hazardous substances. Flinn makes it safer by providing PVC-coated
bottles, Flinn Saf-Cube™ and premixed solutions.
Safer Bottles
For your safety, please order the 2.5 L ammonium hydroxide in the PVC-coated bottle (A0227)—
these bottles are lifesavers!
See free video at flinnsci.com.
Saf-Cube™
All 14.8 M ammonium hydroxide bottles are shipped in Flinn Saf-Cubes™ for your protection.
Don’t throw these valuable containers away. They make great storage containers if no acid
cabinet is available.
Premixed Solutions
Consider buying Flinn premixed ammonium hydroxide solutions. They save time and are safer
to store than concentrated bases. If you make your own solutions…
Always Add Base to Water!
