Described connector is constituted by socket and the inner feed tube of outside, and described feed tube is the test tube shape, and front opening is communicated with the adapter sleeve in the place ahead, and rear portion round bottom projection one prong is offered inlet opening at the sidepiece of prong;
Described O-ring seal is made of elastic body, is step-like, first half inwall and socket outer wall coupling, latter half inwall and Reagent Tube outer wall coupling;
Reagent Tube is pipe, and the two sections inner chambers in front and back cut off the leading flank close encapsulation film of leading portion.
Further, equal the external diameter of Reagent Tube at the internal diameter of described socket, Reagent Tube inserts distance mobile in the socket can make prong stab out diaphragm seal on the Reagent Tube.
Further, described internal diameter capillaceous is 1.0 to 1.5mm.
The structure-improved of the quantitative sampling reagent adding device that the utility model provides, described sampling head is fixed on two poles that are angle by the kapillary of plastics needle tubing shape and connects and composes, two poles are fixed on the connector of hollow tubular, then insert and be fixed in the adapter sleeve of connector front opening, product sampling head and the connector finished are to be fixed together, do not need again kapillary in addition, specially to be inserted connector in use, avoided many adverse effects and the consequence brought by insertion as previously mentioned.
The beneficial effects of the utility model than prior art, have reduced operational sequence, have saved the operation staff; Avoid insertion capillaceous that curved, slotting folding even the cracked situation generation of glass tube occur to insert; Stopped the leakage situation between kapillary and support, guaranteed that test accurately; Also avoided inserting the impact that test result is produced of being infected with in operation and the external world.
