Uses:
Projection Abbe Refractometer is a kind of instrument which can be used to
determine the refractive index nd and the mean dispersion n
F
- n
C
for the
transparent or semitransparent liquid or solid (mainly used to determine the
transparent liquid).
With the help of thermostat, this instrument may be used to
determine the refractive index n
d
for the substance within the
temp. range from O o C to 50 o C The refractive index & the
mean dispersion are important optical constants; with which
the optical property of purity, concentration and
dispersion power, etc. can be determined for a
certain substance. Therefore, this
instrument has been used widely; it is an
indispensable common one used in the
industries of chemicals, grease, pharmacy,
painting, food processing.

and scientific research institutes.

BRIX Scale (%):
The Brix degree measures the concentration percentage of soluble solid content of a sample (aqueous solution), i.e. the sum
of all the solids dissolved in the water (sugar, salt, proteins, acids, etc.); the measurement result is their sum in the sample.
Basically, the Brix degree is calibrated to the grams of cane sugar contained in 100 g of solution. For this reason, when a
sugar-based solution is measured, the Brix degree precisely calculates real concentration. In the event of the substance to be
examined also containing other components different from sugar, a referement should be a conversion table, so as to correct
the obtained values and make sure the result represents the exact sample concentration.
