The luminometer accepts samples in 12 mm diameter test tubes with lengths ranging from 45 to 100 mm and 15 mL microcentrifuge tubes.

光度计使用45～100纳米的波长范围，12毫米直径的测试管和15毫的微量离心管。

Surface water is generally coloured and turbid.When total phosphorus is analyzed by luminometer, the monitoring result will be somewhat high.

地面水一且浊，采用光度法分析水样中总磷时，会使测定结果偏高。
