How to select the test tube Generally the round test tube is not for optic purpose unless it is pre-checked strictly. We can select it as follow: 1. Check size. (The size should be f12+0.4×100 mm) 2. Check the surface of tube. (It should be no bubbles, no scabs, no thread like things.) 3. Warming instrument according to § ~ § and set the wavelength at 360 nm. 4. Pour some pure water into tube and insert it to the test tube well in sample apartment. Check it just as § Then put some mark on the tube opposite the white mark at the instrument. 5. Put the other test tube into instrument one by one and get the readout for everyone and put mark at everyone. We can divide them in many groups. In each group the differential of readout for every tub is less then ±0.02A. 6. Then we can use tubes in same group for blank, sample, and standard solution needn’t check the tube every time.
