Abbe Refractometer - Visual Laboratory Refractometer - 1.3000-1.7000 nD - 0-95% Brix

The Master Science Abbe Refractometer is a classic visual benchtop refractometer for measuring refractive index (nD), mean dispersion (nF-nC) and sucrose Brix of transparent and translucent liquids and solids. The operator aligns the borderline in the eyepiece and reads the value from an optical index plate, giving dependable results without electronics in the optical path.

Only one or two drops of sample are required, and a built-in flow cell can be connected to a circulating bath for constant-temperature measurement, monitored by a digital thermometer.

Key Benefits

• Tiny sample need: one or two drops are enough, ideal for valuable or trace samples.
• Durable prism: the hard glass surface resists scratches and chemical attack.
• Accurate at set temperatures: the Master Science Abbe Refractometer connects to a water bath for controlled-temperature work.
• Simple and robust: visual reading means no software, batteries or complex maintenance.
• Teaching friendly: students learn the optical principle directly through the eyepiece.

Labs wanting automatic readings can upgrade to the Master Science automatic digital refractometer.
