Abbe Refractometer Model C10
The VEE GEE Model C10 Abbe Refractometer is an excellent instrument for the Refractive Index (nD) analysis of liquids, glass, plastic, and film.
The VEE GEE C10 has been referenced in scientific studies on refractometry for its high-precision measurements in both laboratory and industrial applications. Customer reviews highlight its accuracy, ease of use, and reliable temperature control, making it popular in food and beverage testing, chemical laboratories, and quality control for plastics and glass. Users often cite its durability and versatility for both routine Brix measurements and advanced refractive index analyses.
Operation Overview
The operation consists of placing a sample on the prism; while looking through the eyepiece, the control knob is turned until the Shadowline is centered in the crosshairs. The reading is taken where the vertical line crosses the scale. Calibration is performed with water.
Primary Features
Primary features include an oversized, easy-to-read scale; digital analysis and readout of prism temperature; Refractive Index (nD) & Brix scales; primary & secondary prisms; color compensator dial; and a large measurement dial with a focusable eyepiece.
Prism Temperature Control
For prism temperature management, the C10 comes with 2 circulator nozzles for the primary prism and 2 for the secondary prism, allowing connection to a circulating bath for precise temperature regulation. The prism temperature is displayed on the LCD at the base of the refractometer. The effective temperature range is 0 to +70°C.

Q&A
What liquids can the VEE GEE C10 measure?
The C10 can measure a wide range of liquids including water, oils, juices, and chemical solutions, as well as glass, plastic, and film samples for refractive index analysis.
How is the refractometer calibrated?
Calibration is performed using distilled water. Place a drop on the prism, focus the eyepiece, and adjust the control knob until the Shadowline aligns with the crosshairs, then read the scale.
Can the prism temperature be controlled externally?
Yes, the C10 has nozzles for connecting to an external circulator or bath, which allows precise temperature regulation of the primary and secondary prisms between 0 and 70°C.
Is it suitable for both Brix and refractive index measurements?
Yes, the refractometer includes scales for both Brix and Refractive Index (nD), making it versatile for laboratory and industrial testing.
What is the benefit of the color compensator dial?
The color compensator dial allows accurate measurements by correcting for chromatic aberration when using different light sources, improving precision in refractive index readings.

| Transparent or translucent film samples can be measured with the use of a glass standard (aids in the illumination of the sample), contact liquid (adheres the sample to the glass standard and to the primary prism), and an external sodium light source package, 44000-LEDNA (sold separately). Note: The refractive index of the sample must be lower than that of the contact liquid and the glass standard. The included bromonaphthalene contact liquid has a refractive index (nD) value of 1.6300. The included glass standard has a refractive index (nD) value of 1.5163. Transparent or translucent glass samples can be measured with the use of a contact liquid (adheres the sample to the primary prism) and an auxiliary sodium light source package, 44000-LEDNA (sold separately). Note: The refractive index of the sample must be lower than that of the contact liquid. The included bromonaphthalene contact liquid has a refractive index (nD) value of 1.6300. | ||||
