Search this site!

Many of the supplies used in biodiesel titration can be found around the house, but be sure not to use them for anything else (especially food use) once they have been exposed to the catalyst!

Titration Supplies:

Containers for Titrating Oil

• Container - plastic or glass, needs to hold 1 liter and be re-sealable; it is for storing the titration solution in.

• 3 small cups - (plastic or glass), they need to hold 1/4 cup (about 50 ml) or more.

• Distilled water (tap water may not be pH neutral).

Chemicals for Titration: Phenolphthalein, Isopropyl Alchohol, Catalyst

• Isopropyl alcohol (30 ml) - with a purity of at least 90%.

• Catalyst - either Potash or Lye (only 1 gram will be needed).
