Stirring Rods

Glass and polyethylene stirring rods for use in the science laboratory.

A stirring rod is used to mix liquids or solids and liquids together.

When decanting supernatants, stir rods are utilized as part of correct laboratory technique because the contact serves to negate the adhesion between the side of the glassware and the supernatant, which is responsible for the liquid pouring down the side. Using a stirring rod also allows for greater control over the velocity of flow, which is critical in situations where chemicals may react violently. This method is also used to transfer liquid from a large-mouthed flask or beaker into a test tube.

Stirring rods can also be used to scratch the interior surface of a test tube or beaker to generate crystallization in a recrystallization operation.

They can also be used to break apart an emulsion during extraction.
