New abbe refractometer 0-95% brix, atc 4 lab - deal
This Abbe refratometer is an excellent, affordable instrument for the refractive index (nD) analysis of liquids, glass, plastics and film.
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. Calibrates with water. Uses strong ambient light to work!
* Oversized, easy to read scale
* Refractive index (nD) and Brix scales
* Primary and secondary prisms
Featuring 2 circulator nozzles for the primary prism and 2 for the secondary prism, model 2WAJ can be connected to a circulating bath to accurately regulate prism temperture. The prism temperature is displayed on the external glass thermometer. The effective temperature range is 0-70 C
Transparent or translucent film samples can be measured with the use of a glass standard (aids in the illumination of the sample), contact liquid (adhered the sample to the glass standard and to the primary prism), and an external sodium light source (sold separately).
The refractive index (nD) value of the sample must be lower than that of the contact liquid and the glass standard. The included bromonaphtalene contact liquid has a refractive index (nD) value of 1.6300. The included glass standard has a refractive index value (nD) of 1.5163.
Transparent or translucent glass and plastic samples cam be measured with the use of a contact liquid (adheres the sample to the primary prism), and an external sodium light source (sold separately).
The refractive index (nD) of the sample must be lower that that of the contact liquid. The included bromonaphtalene contact liquid has a refractive index (nD) value of 1.6300.
