Description

Novel pipette rack

Technical Field

The invention relates to an experiment auxiliary device, in particular to a pipette stand in experiments in the fields of biology, medicine and the like.

Background

In experiments in molecular biology, microbiology, medicine and other disciplines, a pipette is needed to measure reagents, and in a specific operation, a dedicated pipette is usually configured for each reagent to prevent the reagents from being polluted. The pipette rack known at present has the modes of horizontal placement, vertical suspension and the like, or the combination of the two modes, but the pipette rack and the reagent bottle cannot be placed in one device at the same time.

Such as the following patent documents:

patent document 1: authorization notice number CN 204583237U;

patent document 2: authorization notice number CN 203389678U;

patent document 3: authorization notice number CN 204122157U;

patent document 4: grant publication number CN 202741175U.

Document 1 designs single supports with different specifications, and the supports are linked by I-shaped wedges and can be freely combined according to experimental requirements, so that the problem that the jack specification of the pipette rack is single is solved; the pipette rack described in document 1 has functions of placement, liquid collection, and the like, but the entire structure is an open structure and cannot meet high-standard experimental requirements.

Document 2 divides a cylindrical space into a plurality of independent areas according to a sector by using partition plates, thereby solving the problem of pipette isolation, wherein each sector is provided with a support plate with different apertures, which can be used for placing pipettes or test tubes with different specifications, so that the instrument holder has strong universality, and the bottom is provided with a liquid collecting tank, thereby solving the problem of single function; however, the instrument holder described in document 2 still has an open structure, pipettes of the same specification still co-exist in the same space, and need to be aligned with the circular holes when placing and taking out the instruments, so that the instruments are easy to contact with the holder, and the operation is inconvenient, which causes pollution.

Document 3 fixes a pipette by a clip, and realizes control of the position of the pipette; however, the pipette holder disclosed in document 3 has problems such as the open type and the need to align with the circular hole, which are similar to those of document 2.

Document 4 is to provide an openable and closable dust cover on a general pipette holder with a disk structure, so as to solve the problem that foreign matters such as dust and the like contaminate a pipette in an open structure; however, the pipette rack described in document 4 still has a problem that pipettes are placed in a concentrated manner and cannot be isolated individually.

In the prior art including the above documents, there is no solution for pairing and placing the pipette and the reagent bottle separately, but in the experiments in the fields of biology, microbiology, medicine, etc., live bacteria experiments are often involved, each reagent is required to be equipped with a separate pipette, and in the experiment process, it is ensured that separate reagent bottles and pipettes are arranged to avoid mutual pollution.

Disclosure of Invention

In order to solve the problems, the invention designs a novel closed pipette stand with independent space and isolated instruments, which can realize the independent placement of a reagent bottle and a pipette, and the closed structure plays the roles of isolating the reagent bottle and the pipette from the outside and facilitating the taking.

The technical scheme adopted by the invention for solving the technical problem is as follows: comprises a base, a rotating shaft, a tray, a clapboard, a clamp, an outer cover, a top cover, a cover plate and an arc door; the pivot mainly comprises fixed part and rotating part, and top cap and base are connected with the pivot fixed part, and the tray is located above the base, and the apron is located below the top cap, and tray and apron and pivot rotating part are connected, are provided with the baffle between tray and the apron, set up the clip in the pivot, and the dustcoat encircles the encirclement along top cap and base, and the arc door is laminated with the dustcoat both sides.

Further, the number of the partition plates is set to be plural.

Further, the number of the clips is set to 2.

Further, a liquid collecting groove is formed in the tray and is located right below the clamp.

Furthermore, the outer edge of the tray is provided with a baffle.

Further, the diameter of the tray is larger than that of the cover plate.

Furthermore, the outer cover is provided with an opening, and the size of the opening is the same as the distance between two adjacent partition plates.

Furthermore, the arc door can slide into the outer cover along the edge of the base, and the arc door is provided with a sensing device.

Furthermore, two sides of the opening of the outer cover are provided with induction devices.

Further, a label window is arranged on the partition plate.

The pipette rack has the advantages that the pipette rack is divided into a plurality of independent areas in a closed space, so that reagent bottles and pipettes placed in the pipette rack are isolated from each other, the possibility of cross contamination between the reagent bottles and between the pipettes is reduced to the maximum extent, meanwhile, the pipette rack also has the functions of placing the reagent bottles, collecting liquid and marking, multiple purposes are realized, the opening and closing of the arc-shaped door and the rotation of the tray are controlled by the pipette rack through the induction device, and the operation of personnel is greatly facilitated.
