Titramax VT TAN/TBN
Determination of total acid or base number of oils and fats
Product description
The TAN/TBN Titrator Titramax VT TAN/TBN is suitable for determination of Total Acid Number (TAN) or Total Base Number (TBN) of oils and fats. The acid number expresses the quantity of base required to neutralize all acidic constituents of the sample. It is a quality feature for freshness of oils and fats. The base number indicates the quantity of acid which can be neutralized by additives in mineral oils.
The device is conform to standards ASTM D 664, DIN 51558, IEC 62021-1, Pharmacopoeia (TAN) and ASTM D 2896, ASTM D 4739, ISO 3771, UOP 269 (TBN).
The measurement uses a potentiometric titration method in an anhydrous medium. The titration with titrant starts, once the oil sample is dosed into the reagent. The user has to enter the sample weight into the menu. The titration speed is precisely adjusted to the reaction rate by control algorithms.
The titration is performed automatically until the endpoint indication of measurement. At the end of the measurement, results are shown in mg KOH/g oil or several other units.

Applications
The value of TAN/TBN is an indication of age and quality of oils and fats. The device is suitable for analysis of
- transformer oils
- natural and artificial fats
- mineral oil products
- lubricants
- food fats (e. g. olive oil, butter)
Advantages
- Complete measuring system for the determination of TAN/TBN
- Fully-automatic volumetric titration
- Precise adjustment of the titration parameters by control algorithms
- Preset measurement method allows an immediate start
- The result output can be adjusted to your needs by using a formula generator
Features
The Titramax VT TAN/TBN consists of
- an automatic volumetric titrator with potentiometric pH indication,
- a titration vessel with stirrer unit.
The determination of TAN/TBN value is based on
- an acid-base-titration in an anhydrous medium,
- a precise indication by an electrode filled with anhydrous ethanol/LiCl
Steps of the analysis
- Calibration of the electrode
- Determination of the blank value
- Standardization of the titration solution
- Titration of oil samples
