All-in-One refractometer and polarimeter hybrid unit. Only 3 ml sample is needed. With the press of a button, purity, international sugar scale, specific rotation and concentration can be displayed. Users can also set an upper and lower measurement limit. An indicator light alerts the user if a measurement value is within the limits.

RePo-1: can measure both brix and optical rotation of the sample.
RePo-1 Package includes: Main unit, 100 ml beaker, 50 x Syringe Filters orange 45, 3 x 20 ml Syringes, 100 x Easy filter.

RePo-2: As RePo-1, additionally the RePo-2 also determines and displays the amount of fructose (%) within HFCS. The RePo-2 is ideal for various industries such as food and beverage, or sugar refining.

RePo-3: As RePo-1, additionally the RePo-3 also determines and displays the amount of invert sugar (%) derived from sucrose. The RePo-3 is ideal for various industries such as sugar refining.

RePo-4: As RePo-1, additionally the RePo-4 also determines and displays the amount of fructose (%) and honey moisture (%). The RePo-4 is ideal for total quality control of honey.

RePo-5: As RePo-1, additionally the RePo-5 can also display the refractive index (nD) of a sample. The RePo-5 is ideal for quality control in various industries such as fragrances, cosmetics, or pharmaceutical.

Handy and precise. Angle dispersion C -F: 7°. Linear dispersion: 60 mm (direct vision prism of Amici type)
Ideal for demonstrations in schools and for:

• Viewing / observation of emission and absorption spectra
• Control of the wavelength spectra of gas emission lamps

Model AP-300 is generally used in pharmaceutical, perfume, cosmetic, industrial, chemical, and food factories and is the optimal unit for measuring angle of rotation. In addition, the built-in International Sugar Scale is widely used in sugar refineries.
The AP-300 has a manual calibration facility which allows the user to compensate for any differences to standard liquids and measurement values by other standard instruments.

For basic lab applications and training, for example the experiment on saccharose inversion.
