They are lowered in an 'open' state to the required DEPTH and can be closed before being hauled up by means of a MESSENGER. Water bottles can be operated in series that is with more than one bottle on the wire rope so that WATER SAMPLES can be taken at a number of DEPTHS on the same CAST. Also called water specimen cup.	从不同深度采集水样的装置。当它们放入所需深度时，使用信号发生器，将其置于“敞开”状态。提起前�... more 从不同深度采集水样的装置。当它们放入所需深度时，使用信号发生器，将其置于“敞开”状态。提起前可以将其关闭。也可用一组采水器采样，此时，将几个采水器捆在一条索上，可以在一次投水中获取不同深度的采样。亦称water specimen cup。

The bottle is lowered by wire and can be closed watertight at any desired DEPTH, by means of a MESSENGER allowed to slide down the wire and strike the reversing mechanism making the bottle turn upside down. Thus the enclosed WATER SAMPLE is not contaminated by water at higher levels or lost by leakage after the bottle is brought on board. REVERSING THERMOMETERS are attached to reversing water bottles. See EKMAN BOTTLE and NANSEN BOTTLE.	NULL
