Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco processing and detection, and particularly relates to a pipette support for a laboratory. Background Art

[0002] During the production process, cigarette industry enterprises need to conduct chemical composition analysis on in-process and finished cigarettes. Among them, standard solutions are required for routine analysis of chemical indicators such as sugar, alkali, chlorine, potassium, and detection of nicotine content in smoke. At present, the standard solutions used in laboratories are all modulated by laboratory personnel using standard stock solutions. During the modulation process, the conventional quantitative sampling tools are pipettes or pipette guns. When there is a significant deviation in the precision and accuracy of the pipette or pipette, resulting in the actual pipetted liquid volume being significantly inconsistent with the set volume, laboratory personnel need to use pipettes for quantitative sampling. Since pipettes are glass products and are not used frequently, they require a special bracket for fixed storage to avoid problems such as bottom breakage caused by bumps. In summary, the utility model provides a laboratory graduated pipette holder that can safely and conveniently achieve fixed storage of pipettes. Utility Model Content

[0003] The purpose of the present utility model is to provide a laboratory pipette holder to solve the problems existing in the above-mentioned background technology.

[0004] To achieve the above objectives, this application is implemented through the following technical solutions:

[0005] A laboratory pipette stand comprises a base and a support frame arranged on the base, wherein the support frames are two or more and two adjacent support frames are arranged in parallel.

[0006] Each support frame is provided with a plurality of card slots for receiving and storing graduated pipettes; and an anti-slip strip is provided in each card slot.

[0007] Furthermore, the angle between the support frame and the base surface is 75 。 .

[0008] Furthermore, the structures of the card slots are the same, and the cross-section of the card slots is trapezoidal.

[0009] Furthermore, in the trapezoidal structure of the card slot, the width of the outer opening is 10 mm, the width of the bottom of the card slot is 6 mm, and the depth of the card slot is 8 mm.

[0010] Furthermore, three weight-reducing holes are provided on the support frame.

[0011] Furthermore, reinforcing ribs are provided between the support frame and the base.

[0012] Furthermore, a groove is provided on the lower surface of the base, and a circular rubber anti-slip pad is provided on each of the four corners of the lower surface of the base.

[0013] Furthermore, an opening penetrating the base is provided on the base opposite to each card slot, and a rubber pad is provided in the opening.

[0014] The beneficial effects of the utility model are:

[0015] The utility model realizes the simultaneous storage of multiple graduated pipettes on one bracket by arranging a slot on the support frame and the structure of anti-slip strips and shock-absorbing rubber cushions in the slot, and can effectively avoid collisions caused by the movement of the pipettes.

[0020] The technical solution of the present invention is described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and cannot be interpreted as limiting the technical solution of the present invention.

[0021] like Figure 1 and Figure 2 As shown, the present application provides a laboratory pipette holder, which consists of a base 1 and a support frame 2. In the present application, there are more than two support frames 2, such as two support frames or multiple support frames. The base is rigidly connected to the support frame, and the multiple support frames are arranged parallel to each other. Several card slots 7 are provided on each support frame. In this embodiment, 4 card slots are provided on each support frame, so that 4 graduated pipettes can be stored on each support frame at the same time. Anti-slip strips 8 are provided on the surface of each card slot, which can effectively avoid collisions caused by the movement of the pipette.

[0022] In this application, the base 1 is designed with cast iron and has an external size of 400mm*120mm*20mm. A groove 5 is provided on the lower surface of the base to reduce the weight of the base, and a circular rubber anti-slip pad 6 is provided at each of the four corners of the lower surface of the base.

[0023] In this application, two parallel support frames 2 are mounted on a base 1, forming a 75° angle with the base surface. The support frames are rectangular in shape, measuring 240mm by 120mm by 6mm, and made of acrylic. Each support frame has four rows of slots 7, each with a trapezoidal cross-section, 10mm wide at the top, 6mm wide at the bottom, and 8mm deep. The total length of the slots is 250mm. To reduce weight, the support frames are hollowed out in the middle, with three weight-reducing holes on each frame.

[0024] Each slot 7 of the support frame 2 is provided with an anti-slip strip 8 , which cooperates with the slot and is divided into three sections by a weight-reducing hole.

[0025] In this application, an opening is provided on the base opposite to each slot, and a rubber cushion 9 is provided in the opening to prevent the bottom of the graduated pipette from being broken due to accidental vibration. When in use, the graduated pipette is gently placed in the support frame slot.

[0026] In order to ensure the rigidity of the support frame, a reinforcing rib 4 is provided between the support frame and the base.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
