Multi-gun-head combined device for cell culture pipetting gun

Technical Field

The utility model belongs to the field of experimental equipment, and particularly relates to a multi-gun head combined device for cell culture.

Background

The pipette gun head is a consumable commonly used in cell experiments, the gun heads with different specifications are required to be replaced in experimental operation, repeated opening of gun head boxes with different specifications causes complex experimental operation, and great inconvenience is caused for experimenters.

Cell culture operation needs to be carried out on an ultra-clean workbench, the experimental space is small, materials and reagents required in the experiment are more, wherein gun head boxes with different specifications occupy larger space, the experimental operation is influenced, and cell pollution is very easy to cause. Moreover, in experimental operation, the pipette tip is not comfortable for experimental operation due to the angle problem.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide a multi-gun-head combined device for a cell culture pipetting gun.

In order to solve the problems, the utility model adopts the following specific design and technical scheme:

a multi-gun head combined device for cell culture comprises a gun head box and an inclined bracket arranged at the bottom of the gun head box. The gun head box is internally provided with a plurality of gun head partition boards, the front surface of the box body is provided with a lock catch, the connecting part of the box body and the box cover is provided with a hinge, the bottom of the box body is provided with a notch, and the inclined bracket is positioned in the notch.

Further, the gun head box comprises gun head partition boards with different apertures.

Further, the diaphragm aperture was matched to 1000. Mu.L, 200. Mu.L, 10. Mu.L tips.

Further, the front of the box body comprises a lock catch, and the box cover and the box body are provided with lock catch structures.

Further, the joint between the box body and the box cover contains a hinge.

Further, the bottom of the case body comprises an inclined bracket.

The beneficial effects of adopting above-mentioned technical scheme to produce lie in: the utility model has simple structure and good comfort level of experimental operation. In the use, open box body bottom slope support, the box body is the inclined plane with experimental table-board, has improved the comfort level of experimental operation. Secondly, the device adopts many specifications rifle head baffle, reduces the placing of experimental many specifications rifle head box, has effectively saved experimental operation space, and avoids the change rifle head to make a round trip to lead to the cell pollution phenomenon.

Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings:

as shown in FIG. 1, the multi-gun head combined device for cell culture comprises a gun head box and a base inclined bracket. The gun head box comprises a box body and a box cover, wherein the box body is divided into an upper layer and a lower layer, the upper layer is provided with a multi-specification gun head fixing partition board, and the lower layer is a cavity. The back of the connecting part of the box cover and the box body is provided with a hinge, and the front is provided with a lock catch. The bottom of the box body is provided with a notch, and the base tilting device bracket is positioned in the notch.

Firstly, gun heads with various specifications are inserted into corresponding positions of a box body partition board, and the gun heads are sterilized for standby. When the anti-slip box is used, the tiltable bracket is firstly opened, so that the box body is in a tilting state, and the base anti-slip pad is used for preventing the box body from moving. Subsequently, the lid is opened, and the pipette is inserted into the adapter, and sampling is performed. Finally, the box cover is covered. The device adopts many specifications rifle head baffle, reduces the placing of experimental many specifications rifle head box, has effectively saved experimental operation space, and avoids changing the rifle head back and forth and leads to the cell pollution phenomenon.

The septum aperture was matched to 1000. Mu.L, 200. Mu.L, 10. Mu.L tips. The front of the gun head box body comprises a lock catch. A hinge is connected between the back of the box body and the box cover. The bottom of the box body comprises a base inclined bracket. In the use process, the inclined bracket at the bottom of the box body is opened, and the box body and the experiment table surface are inclined.

The utility model can insert gun heads with different specifications into corresponding holes, and is used for cell culture multi-gun head combined device after high-pressure sterilization. When the multi-gun head combined device is operated, the base inclined support is firstly opened, so that the multi-gun head combined device is placed in an inclined plane. The device has overcome and has needed to dispose a plurality of different specification rifle head boxes in the traditional cell experiment operation, saves experiment operation space, and the device bottom adopts inclined support, has improved the comfort of experiment operation.

The utility model has simple and reasonable structure and good operation comfort. Secondly, the device has effectively saved experimental operation space through many specifications rifle head composite set, avoids experimental operation to make a round trip to change the cell pollution phenomenon that the rifle head leads to.
