Description
Technical field
The present invention relates to experiment equipment, be specifically related to a kind of molecular biology experiment sample mill.
Background technology
At the initial stage nineties, the development of making rapid progress along with molecular biology, molecular biology experiment technology has become the important research tool of each subject of life science.Current most domestic laboratory experiment does not have special instrument for what grind, is all generally common medical stainless steel tweezers.Existing forceps constructions is simple, and mainly comprise tweezers body, tweezers body one end is joint portion, and the other end is the clamping head opened.Joint portion is very thin very flat structure, therefore poor experience is brought when grinding firmly: pain palm can be stabbed because lifting surface area is too little when propping up joint portion force with palm, if do not prop up joint portion, then be difficult to again force, cause grinding operation difficulty, grinding effect is also poor.Adopt the stirring rod of single to carry out agitation grinding in addition, but when single rod stirs, sample easily sticks to lapped face, order increases to loss.Therefore provide mill special in a kind of molecular biology experiment process necessary.
In addition, traditional clamping head lateral surface is without radian, so in experimentation, clamping head medial plane cannot be fitted with the container of radian, the conical tubes that particularly molecular biosciences experiment is conventional, is therefore difficult to sample to grind enough thin.Meanwhile, clamping inner portion mostly is band, can remain more laboratory sample, makes sample loss comparatively large, causes experimental error.
Summary of the invention
For solving the problem, the invention provides a kind of molecular biology experiment sample mill, it is applicable to molecular biology experiment, can ground sample more easily, improves experience.
The present invention is achieved by the following technical solutions: a kind of molecular biology experiment sample mill, it is characterized in that: comprise main body, main body one end is the clamping head opened, and the other end is joint portion, is socketed and is fixed with a spherical afterbody outside this joint portion.
Described spherical afterbody is spheroidal or oval spherical.
Described clamping head lateral surface is the cambered surface of evagination.
Described clamping head lateral surface is less the closer to the radius of curvature of its vertical direction of cambered surface of termination.
Described clamping head lateral surface comprises cambered surface and lower camber side, and the radius of curvature of upper cambered surface vertical direction is 25-30 millimeter, and radian is 12-18 °; The radius of curvature of lower camber side vertical direction is 4-8 millimeter, and radian is 25-35 °.
The chordwise curvature radius of the cambered surface of described clamping head lateral surface is 4-8 millimeter, and radian is 30-45 °.
The direction that described clamping head points to clamping head by joint portion is narrowed, to the termination forming blunt nosed structure.
The radius of curvature of described blunt nosed structure is 1.2-1.8 millimeter.
Described clamping head medial surface is provided with the identical oblique burr of incline direction.
Mill of the present invention adopts spherical afterbody, better grasp during grinding, can ground sample more easily, improve experience, and can use as stirring rod, have and to solve sample while clamping function and easily adhere to problem on the wall, decrease the loss of sample, add conventional efficient.The present invention is specially adapted to the sample grinding of molecular biology experiment.
