比色管

对含泥沙水样消解后不用滤膜过滤而改为直接定容于50mL比色管中，经钼酸盐、抗坏血酸试剂显色后离心，取清液测定。

A water sample containing sediments is solved directly in a comparision tube of 50 mL after its resolution without film filtering , and then is centrifuged after color development by molybdate and ascorbic acid reagent , and finally its clear liquor is determined .

菌体经无菌水洗涤后，转移至比色管中。

The fungal , after washed by sterilized water , was gathered to colorimetric tube .
