Sample cell with parallel walls to reduce refraction or reflection.The light from the sample cell walls, curved, round type which is h wayaphoem onglae man is a Dalian yum to the at the temple.Absorb light.
squares of the sample cell walls parallel. To minimize refraction The reflected light from the sample cell circular curved walls, which are then added to the sample and the accuracy of the measurement the absorption of light.
Sample cell square with walls parallel to each other to reduce the refraction or reflection of light from the curved walls sample cell. ชนิดกลม which will add to the accuracy in 2004 mitigated and man 'in the measurement period to absorb light.
