Azzota PST-N17 Polarimeter Calibration Tube

Azzota® Polarimeter Calibration tube

Features

• Polarimeter Calibration tube
• Optical rotation: +17 or -17
• Sugar degree: -48.51°Z
• The reading is got using the sodium light (effective wave length is 589.44 nm) to perform the measurement at 20.0°C .
• Calculate temperature calibration according to the formula following: At °C =A20.0°C [1+0.000144(t-20)] Where A20.0°C is the reading of standard quartz tube at 20.0°C ; At °C is the reading of standard quartz tube at t°C
