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
Optical rotation 5', 35' available for request
