3. Because the catheter passes from the sealing washer in this scheme, consequently need not to set up the mounting hole on last detection arm again, the processing of being more convenient for like this also prevents simultaneously from going into the cell from last detection arm top printing opacity, produces harmful effects to the analysis result.

Further, the cross section of cell is the rectangle, and two relative lateral walls of cell are the printing opacity face, and two other lateral walls of cell adopt frosted glass to make, and the catheter is kept away from printing opacity face one side and is set up.

Has the advantages that: this prevents the catheter from obscuring the light transmitting surface.

Further, the height of the boss is not more than 15mm, and the width of the boss is not less than 5 mm.

Has the advantages that: the purpose that sets up like this is with the cell through the boss spacing in the inspection hole to operating personnel can get the cell through the boss, and it is more convenient to operate.

Furthermore, a plurality of vertical grooves are formed in the circumferential profile of the boss and are distributed at equal intervals along the circumferential direction of the boss.

Has the advantages that: thus preventing the cuvette from slipping when being taken and placed.

Furthermore, the liquid guide pipe is a hose, and an inverted L-shaped bent pipe positioned at the top of the cuvette is sleeved on the liquid guide pipe.

Has the advantages that: the arrangement of the hose enables the liquid guide pipe to be better installed on the cuvette, and the arrangement of the inverted L-shaped bent pipe enables the liquid guide pipe positioned inside the cuvette to be kept in a vertical downward state.

Furthermore, a hard limiting pipe is sleeved on the liquid guide pipe and is positioned in the first through hole.

Has the advantages that: the catheter tube can better penetrate through the first through hole through the limiting tube.

Further, still be equipped with the exhaust hole that is close to the installation passageway on the boss, inside the exhaust hole intercommunication cell, seted up the second through hole on the sealing washer, be equipped with the blast pipe in the exhaust hole, the one end of blast pipe passes the outside that the second through hole is located the sealing washer.

Has the advantages that: this facilitates the draining and introduction of the sample in the cuvette.

Further, the end part of the exhaust pipe is in threaded connection with a sealing cap positioned outside the sealing ring.

Has the advantages that: after leading-in sample is accomplished, can live the blast pipe seal through sealed cap, reduce external impurity and get into.
