Described clear hard suction pipe is glass material, length 26-30cm, internal diameter 1.5cm, and inserting liquid level one end is angular cut.
Described flowrate control valve is for controlling pipette samples speed control valve, and described ball-type air bag is pipette samples start assembly.
The utility model has the advantages that:
1) can to assemble and structure is simple, in phytoplankton sample settling process, can by clear glass suction pipe and the dismounting of PU transparent hose, silica gel cross recess is in closure state, prevents dust or other foreign matters from entering in sample.
2) be inlaid with the silica gel inner cap of band cross recess in the middle of glass outer-cover, when clear glass suction pipe inserts, suction pipe can be fixed very well, thus adjustable pipette go deep into the height of liquid level.
3) clear hard suction pipe is glass material, can by suction pipe centre-lock, thus be avoided occurring that in siphonic process, the mouth of pipe is encountered settler inwall and causes phytoplankton to be occurred by the situation of a large amount of sucking-off by silica gel cross recess.
4) PU transparent hose end is provided with flowrate control valve, can coutroi velocity very well, thus phytoplankton sucking-off situation is occurred when avoiding suction excessive.
5) settler directly with traditional is supporting, and original settler sustainable use is cost-saving.
Therefore this device can be used for phytoplankton subsiding, water ecological environment monitoring phytoplankton species qualification, density, there is application prospect more widely in biomass statistics.
