Never ever worry again about accurately weighing 1.00 g of KOH and dissolving it in an accurate amount of 1000 ml of water! We prepare much larger batches to ensure high gravimetric and volumetric accuracy, with consequently more precise and better reproducible biodiesel titration results. The designed-for-liquids and chemically resistant UN approved HDPE bottle with conical seal means your KOH solution can be kept indefinitely.
Titrate 1 ml of waste vegetable oil dissolved in pure alcohol or 90 % rubbing alcohol (isopropanol - IPA) drop-wise with our biodiesel titrant solution (KOH 1.000 g/litre) until the colour change from clear to pink occurs. Note the number of ml of KOH solution needed to get the colour change and add 7 to this number. That number is the amount of gram of KOH your vegetable oil will need to be converted to biodiesel fuel, using methanol, per litre of oil.
