PURPOSE:To improve durability and prevent discoloration, lowering of photo- transmittance and damage of a cell by making at least the inner surface of the liquid sampler cell hold a compound with sterilizing function or propagation preventing function against micro-organisms. CONSTITUTION:When a liquid sampler cell for automatic analytical apparatus for biosolutions, environmental measurement and etc. is made of synthetic resin, glass or etc., the inner surface 14 of the cell material 13 is covered with a plastic 15 homogeniously blended with a compound with sterilizing function or propagation preventing function against micro-organisms, for example N-(fluorodichloro-methyltho)phthal-imide and etc. Also, an inlet 16 for a sample solution, an outlet 17, and windows 18a & 18b for photo-transmission are arranged to the cell. Thus it is prevented that transmissivity is lowered, the inlet and the outlet 16 & 17 are blocked, or windows are discolored or transformed because of propagation of micro-organisms. If an electrode is put inside the cell, contamination or the like of the electrode is prevented, and the cell can be used steadily for a long time. |
