Product details

Model Number: 318-A001 Key Specifications/Special Features: Prior to use:Before plugging the plug into the power outlet, ensure that local mains power voltage matches the polarimeter requirementsClose the lid of polarimeter, press the power switch to on position, the sodium lamp will gradually light upWait for the light source to stabilize, rotate the focus knob until visual field became legibleRotate the vernier knob makes the vernier scale aim at zero positionRecording:

Place an empty test tube into the sample chamber

Rotate vernier knob until the visual field appears uniform brightness

Record the measured value of reference point

Filling the sample solution:

Take out the test tube from sample chamber, unscrew the cap, remove the sealing ring and glass disc
Rinse the test tube thoroughly with distilled water
Pour sample solution into the test tube, then screw on the test tube cap
Wipe away the drops of water on glass disc
If necessary collect all air bubbles into the bubble trap
Open the lid of polarimeter, place the test tube into the sample chamber, the bubble trap is upward
Close the lid, clockwise or anticlockwise rotate vernier knob until the visual field appears uniform brightness
Record the measured value
Repeat above measurements 2 times and calculate the average of measured values
Calculation: if the measured values are positive angle (dextrorotatory substance), minus the value of the reference point shall be the actual measured value of the substance
If the measured values are negative angle (levorotatory substance), minus the 180° shall be the actual value ofthe substance

Determination of the concentration:

After the measurement, if you need to determine purity, concentration or proportion of the sample, use the following formula
α=[α]LC
α: optical rotation
[α]: specific rotation
L: tube length (dm)
C: concentration (g/L)

Replacing the sodium lamp

Before replacing the sodium lamp, be sure to disconnect the power plug from the wall outlet

Wait for the sodium lamp to cool down, remove the lamp cover of polarimeter

Pull the sodium lamp from the socket

Insert a new lamp into the socket

Replace the lamp cover again in such a way that the window point in the direction of the polarizer
