Mi450 Photometer for the determination of COLOR & PHENOLS in wine analysis

Mi450 is a user-friendly photometer for monitoring phenols and color in wine analysis.
Determination of total phenols and color in wine is extremely important in order to decide the production process to be used.

Phenols and color develop during the entire course of life of the wine, and are dependent from factors such as pH, sulfur dioxide (SO2) and Dissolved oxygen (O2). The most important molecules are tannins and anthocyanins.

Milwaukee’s Wine - Photometer are manufactured for easy use, are practical and accurate. Ideal for laboratory use.

The photometer has an advanced optical system based on a special tungsten lamp and a narrow band interference filter that allows most accurate and repeatable readings. The instruments are factory calibrated.

Mi450 Kit
Mi450 is supplied complete with: Total phenols reagents, Wine solvents, pipettes, syringes, cuvets with cap, stopper small cuvets, tissue for wiping cuvets, batteries and instruction manual.

Easy Steps
Prepare the sample to be measured with wine or with reagents to measure Color, Phenols or Tint and zero the instrument. Insert each cuvet in the instrument and see the respective reading.
