Further owing to be connected by the oblique line transition phase between epimere core body and the hypomere core body, when being used for reagent bottles such as internal diameter of the bottleneck 17～18.5mm, can firmly core body directly be filled in bottleneck, have easy and simple to handle, easy to use, the advantage of good seal performance, core material are the strong teflon of corrosion stability (fluoroplastic), can contamination reagent.
Further since the inwall at the upper end open place of catheter channel be provided with screw thread and be used for fixing the threaded connection of conduit with threads engaged.Under the catheter channel unused state, can adopt threaded connection to block the catheter channel opening, avoid dust to fall in the bottle, avoid a bottle interior organic solvent volatilization simultaneously.
Further because threaded connection is provided with the through hole that 1/16 core diameter is used for fixing conduit.Can adopt the conduit of 1/16 core diameter to extract a liquid in the bottle, 1/8 and 1,/16 two kind of pipeline can freely be arranged in pairs or groups.
Further owing to be provided with the ring-type projection that is used for close-fitting embedding bottle cap between core cap and the core body.When the internal diameter of the bottleneck of carrier fluid bottle is big, can on bottle cap, be provided with and the cooresponding perforate of ring-type projection diameter, with the direct inlay card of ring-type projection of the adaptive core of conduit in bottle cap, improved the commonality of the adaptive core of conduit, make it be applicable to various carrier fluid bottles, and improved the leak tightness between adaptive core of conduit and the bottle cap.
Further because core body adopts the corrosion resisting elastic polymeric material to form.The adaptive core of conduit adopts inertia, good springiness plastics, can ensure that corrosion resistant performance is good, can also ensure that except that leakage hole other position air-tightness are good.Core material is the strong teflon of corrosion stability (fluoroplastic), can contamination reagent.
