How to use YS3010 to measure egg yolk color difference

Some customers want to measure the egg yolk color to check the quality of egg. 

But how to measure it? Because it is Opaque liquid. 

First we need to use a small tool to take the egg yolk from the egg white. 

Then put the egg yolk into a small glass. 

All are ready to measure. We can put it above the aperture of YS3010 spectrophotometer and use the instrument test button to measure or use the PC software to measure. 

Here are the test images. 

YS3010 is with 8mm aperture, but for this egg yolk color measurement, 8mm and 4mm aperture all are ok. So model YS3020 and YS3060 are all ok to measure egg yolk. 

Here it is YS3010 specification.
