Rank is interference fitted with groove, and the vertical section of the mouth of pipe is isosceles trapezoid, and the body first half is cylindrical tube, and lower half is taper
Body, conical tube is surrounded by taper tube wall, and the bottom of conical tube is its bottom, and the lower surface of its bottom is body bottom
Face, body bottom surface is plane.
It is preferred that, the external diameter of the cylindrical tube of described body is that 8.0mm, thickness are 0.5mm, the bottom of conical tube
External diameter be 3.0mm, angle of inclination be 18 °, thickness be 0.3mm.
It is preferred that, a diameter of 4.0mm of described concave plane mirror, thickness is 0.8mm, concave plane vertex face and lid top surface
Distance be 0.5mm.
It is preferred that, a diameter of 5.1mm of described arc steps peak, groove top is from being 2.8mm with a distance from the mouth of pipe.
It is preferred that, a diameter of 6.5mm of the described mouth of pipe, highly it is 1.5mm.
It is preferred that, it is hemi-spherical cavities, a diameter of 2.6mm in described its bottom.
It is preferred that, described lid is formed in one with body and material is identical.
Advantages of the present invention：The present invention is simple and reasonable, and easy to use, lid is imported into body by mouth of pipe inclined-plane
Groove in, make step in lid can interference in groove, reach good sealing effectiveness, reduce evaporation rate, improve reality
Test the accuracy of data；The angle and wall thickness of body taper surface are reasonable in design, improve consistent with the cooperation of PCR instrument adapter
Property, experiment cycle period is improved, the cracking probability of tapered wall and conical bottom is reduced, prevents PCR instrument to be contaminated；Lid top surface
If concave plane mirror, it is difficult to be worn, scratches；Its bottom is designed as plane, convenient placement upright on the table.
