Abstract
The utility model relates to a disposable squirt head special for electrophoresis cut gel recycle, which can be matched with a liquid transfer device, and comprises a gel cutting head and a sleeve arm, wherein the gel cutting head is a square groove; and the groove is connected with the sleeve arm through a through hole. During the use, the disposable squirt head has the characteristics of simplicity and convenience in operation, simplicity in gel pushing and low cost, and during the gel cutting process, a cut strip is not liable to fall in the squirt head, and cut gel strip is not liable to fall off during the move process.
Description
Technical field
The utility model relates to a kind of instrument that is used for biology field, particularly a kind of disposable gel cutting gun head that is exclusively used in electrophoretic band cutting recovery.
Background technology
The method that present molecular biology test chamber cuts electrophoretic band is to downcut the purpose band with cutter or blade, reclaim with related tool again and deposit, but be difficult for downcutting accurately whole band owing to cut glue with cutter or blade, and be subjected to the impurity protein contamination easily, so domestic enterprise, the gel cutter sweep of TIANGEN Biotech (Beijing) Co., Ltd. invention (application number: 200820135628.2) just can cut electrophoretic band, but there is troublesome poeration in this device and as the higher shortcoming of disposable apparatus cost for example; By people such as Han Yong this is improved, designed disposable gel cutting gun head (application number: 200910009086.3), make nonrecurring cost obtain reduction, but this gel cutting gun head is because the front portion is the less square Jiao Kou of cutting, the rear portion is taper or cylindricality, when the cutting band, makes band fall into the part of expanding of rifle back of head easily, and out of position and with rifle head space when big when band, pipettor is difficult to its release by air.And fixedly adhesive tape of a frictionally is cut behind the glue all in these two inventions, and what have therefore that band drops in the moving process after cutting may.
The utility model content
In view of this, the purpose of this utility model provides a kind of disposable gel cutting gun head, and this gel cutting gun head cost is low, in cutting the glue process, is not easy to make band after the cutting to fall into the inner and adhesive tape that cut of rifle head and is difficult for dropping in moving process.
Disposable gel cutting gun head described in the utility model is installed on the front end of pipettor, is made up of the cover arm 2 of cutting glue head 1 and be attached thereto, and the described glue head 1 of cutting is a square groove, links to each other by a through hole 3 between groove and the jacket wall 2.
Further, the described glue head 1 of cutting is rectangular recess.
The utility model has improved the structure of disposable gel cutting gun head, cut glue head 1 and adopt groove structure, and and the structure of overlapping design one through hole 3 between the arm 2, help like this preventing adhesive tape fall into the cover arm 2 in, and through and the supporting use of liquid-transfering gun, can prevent to cut back adhesive tape adhesive tape in moving process by the friction force of the suction of pipettor and adhesive tape and drop.Therefore disposable gel cutting gun head of the present utility model, not only cost is low, and in cutting the glue process, is not easy to make the band after the cutting to fall into rifle head inside.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of instructions, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the utility model disposable gel cutting gun head structural representation;
Fig. 2 is the utility model disposable gel cutting gun head upward view;
Fig. 3 is the scheme of installation of the utility model and pipettor.
Embodiment
As shown in Figure 1, disposable gel cutting gun head described in the utility model is installed on the front end of pipettor, is made up of the cover arm 2 of cutting glue head 1 and be attached thereto, and cutting glue head 1 is a square groove, is preferably rectangle, and the shape with adhesive tape is identical like this, cuts glue easily; Between groove and jacket wall 2, be provided with a manhole 3.In operating process, at first disposable gel cutting gun head is locked on corresponding pipettor, as shown in Figure 3, press pipettor suction tube piston, the target electrophoretic band that aligning will cut (target stripe is just in time fallen into cut glue head groove) inserts and cuts, all around slightly rock, cut off band and getting in touch of glue on every side, unclamp pipettor suction tube piston, by the suction and the adhesive tape of liquid-transfering gun and the friction force of cutting the glue head purpose band is moved to the purpose container, promote liquid-transfering gun suction tube piston the end of to, the purpose band is released, fall into corresponding container.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. disposable gel cutting gun head is installed on the front end of pipettor, it is characterized in that: by cut glue head (1) with cut the cover arm (2) that glue head (1) links to each other and form, the described glue head (1) of cutting is a square groove, links to each other by a through hole (3) between groove and the jacket wall (2).
