Abstract
The utility model relates to a laboratory instrument, in particular to a pair of centrifuge tube cover opening tweezers which is used for clamping the opening of a centrifuge tube and opening a tube cover. The pair of centrifuge tube cover opening tweezers comprises two tweezer arms which are fixedly connected at the rear ends, a plurality of grooves are formed in the inner sides of the middle sections of the tweezer arms, colored marking bars coat the inside of the grooves, and anti-sliding frosted face layers are arranged in the grooves. According to the pair of centrifuge tube cover opening tweezers, a protrusion at the opening of the centrifuge tube and the grooves of the tweezers right coincide with each other, force can be conveniently exerted, the centrifuge tube can not slide easily, and using is convenient and safe.
Description
Technical field
The utility model relates to the equipment that a kind of laboratory is used, specifically a kind of centrifuge tube tweezers of uncapping.
Background technology
Centrifuge tube is one of the most frequently used device of fundamental sum in the experiment of life science, especially biology field.Because existing microcentrifugal tube design is upper, the experimenter is when the operations such as open pipe, and finger or opener tend to inevitably touch the pipe close part, thereby cause the pollution of sample in pipe.Generally, when laboratory operation uncap especially centrifuge tube, often can carry out with tweezers, so both can avoid the cross pollution of sample, can reduce with hand and uncap to people's injury again, and the easy sterilization of tweezers can facilitate repeatedly utilization.And our present conventional tweezers are more flat due to contact-making surface in use, the easy landing of centrifuge tube.And, when uncapping, because dynamics is difficult to grasp, can cause to overexert and cause managing content and overflow.
Summary of the invention
The purpose of this utility model, be exactly the problem existed for solving prior art, and designed a kind of centrifuge tube tweezers of uncapping, and the protrusion of centrifuge tube opening part and the groove of tweezers are overlapped just, is convenient to firmly, and is difficult for landing.
The technical solution of the utility model is: a kind of centrifuge tube tweezers of uncapping, and for the mouth of pipe that clamps centrifuge tube and raise the pipe lid, it comprises two tweezer arms that rear end is fixedly connected with, the inboard, stage casing of described tweezer arm is provided with some grooves; Scribble the colour-coded bar in described groove; Described inside grooves is provided with anti-skidding frosted surface layer.
The free end adaptation of described tweezer arm has the Antislip plastic gum cover, and is provided with on garment bag and puts sliding line.
Described tweezer arm upper groove at least is provided with two, and is symmetrically set between two tweezer arms.
Described groove is strip.
The length of described groove is 5-20mm, and width is 0.5-5mm, and the degree of depth is 0.2-2mm.
The beneficial effects of the utility model can draw by such scheme: owing to being that two bars at tweezers design corresponding groove, cover the size of opening part according to the centrifuge tube pipe, design the groove of different large minispreads.For the ease of distinguishing, different grooves can carry out the mark of different colours.The protrusion place of centrifuge tube opening part and the groove of tweezers overlap just like this, are convenient to firmly, and are difficult for landing.And more convenient for what use, all design this groove in the both sides up and down of tweezers two bars, the user picks up at random tweezers and can use like this, and needn't rotate tweezers again.
As can be seen here, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
the accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is for being used state diagram.
Wherein, 1 is the tweezer arm, and 2 is groove, and 3 is garment bag.
the specific embodiment:
In order to understand better the utility model, below in conjunction with accompanying drawing, explain in detail embodiment of the present utility model.
The specific embodiment: a kind of centrifuge tube tweezers of uncapping, for clamping the mouth of pipe of centrifuge tube and raising the pipe lid, it comprises two tweezer arms 1 that rear end is fixedly connected with, and the inboard, stage casing of described tweezer arm 1 is provided with six grooves 2, each tweezer arm 1 is provided with three, and the groove 2 between two tweezer arms 1 is symmetrically set.Described groove 2 is strip.The length of groove 2 be 10mm,, width is respectively 2mm, 4mm, 5mm, the degree of depth of groove 2 is 1mm.Scribble the colour-coded bar in groove 2; Described groove 2 inside are provided with anti-skidding frosted surface layer.The free end adaptation of described tweezer arm 1 has Antislip plastic gum cover 3, and is provided with on garment bag 3 and puts sliding line.
Above-mentioned explanation is not to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
