Description

Microbiology laboratory multi-use test tube pipette rack

technical field

The utility model relates to a laboratory appliance, in particular to a multi-purpose test tube pipette rack for a microbiological laboratory.

Background technique

Test tubes, droppers and pipettes are common glass instruments in experiments, which are often used for taking and storing liquids, and are mostly used in experiments in the fields of chemistry, materials science and biology. Usually, in experiments, test tubes, droppers and pipettes are equipped with corresponding instrument racks, such as: test tube racks, dropper racks and pipette racks. These instrument racks are all special-purpose, generally can only be placed a kind of glass instrument, are used for placing test tube as test tube rack, and pipette rack can only be used for placing pipette, can not accomplish universally. This approach not only occupies laboratory space, but also causes idle and waste of resources. At the same time, laboratory biosafety is a practical issue of great concern at present. In order to avoid microbial contamination in all aspects of microbial experiments, higher requirements are put forward for laboratory equipment and supplies. When the existing test tube rack and pipette rack are placed on the experimental bench, in microbiological experiments, the pipettes that have been in contact with live bacteria are stored on the pipette rack, and the residual bacterial suspension at the tip of the pipette may drip. If it flows onto the base, or even onto the test bench, it may cause bacteria to spread and easily cause contamination of the test bench and the laboratory.

Utility model content

The utility model overcomes the problem that the instrument rack in the prior art cannot be used universally, occupies the space of the test bench, and the pipettes that have been in contact with live bacteria are stored on the pipette rack, which may cause the bacteria to diffuse and pollute the test bench, and provides a structure Simple, easy-to-use microbiology laboratory multi-use test tube pipette holder.

The technical solution of the utility model is to provide a microbiological laboratory multi-purpose test tube pipette rack with the following structure: it contains a base, a rack shaft and a top plate, and there are a plurality of partitions between the base and the top plate along the radial direction around the rack shaft Arranged, the middle part between the two partitions in the vertical direction is fixedly connected with the test tube support plate and the pipette support plate, and the corresponding area between the two partitions on the top plate is provided with holes with different diameters. A liquid collecting tank is arranged under the tube supporting plate, and both the pipette supporting plate and the liquid collecting tank are detachable structures. There are flat-bottomed cylindrical depressions on the test tube holder and holes on the pipette holder. The large-diameter holes, the medium-diameter holes, and the small-diameter holes on the top plate are located in different regions between the two partitions. The pipette support plate, the liquid collection tank and the partitions are snap-connected, and the partitions are colored partitions or transparent partitions, and the number of them is 3≤N≤6.

Compared with the prior art, the utility model microbiology laboratory multi-purpose test tube pipette rack has the following advantages: the present invention achieves one thing with multiple functions, combining the test tube rack and the pipette rack into one, besides having the pipette rack , In addition to the function of the test tube rack, it can also store common tools in microbiological laboratories such as ear washing balls, glass rods, inoculation rods, coating rods, and funnels, saving space on the experimental table. There are flat-bottomed cylindrical pits with a depth of 1 mm on the test tube support, so that when placing glass rods, inoculation rods, coating rods, etc. on the original rack, the glass rods, inoculation rods, and coating rods will not slip off. Especially for the problem of microbial contamination, for the contaminated parts that may come into contact with microorganisms, a detachable pallet and liquid collection tank can be removed and sterilized in time, which minimizes the chance of microbial contamination of the laboratory. The colored partitions or transparent partitions in the device are pasted with colored cards, which can be used as a background to facilitate the observation of the color and changes of the liquid in the test tubes placed on the shelf. When inoculating and cultivating microorganisms, it is also convenient to observe the growth of microorganisms.

Detailed ways

In the description of the drawings, the number 1 is the top plate, 2 is the base, 3 is the partition, 4 is the rack shaft, 5 is the pipette support plate, 6 is the hole, 7 is the pit, 8 is the liquid collection tank, and 9 is the test tube holder plate.

Below in conjunction with the accompanying drawings and specific embodiments, the utility model microbiological laboratory multi-purpose test tube pipette rack will be further described: There are different holes with different diameters, one is the small test tube area, which can hold test tubes of 18mm*180mm and smaller; the other is the large test tube area, which can hold 20mm*200mm test tubes; the other is the pipette area. There are 3 partitions radially arranged around the frame axis in the vertical direction. There are 1mm deep columnar pits on the support plate for test tubes, which can prevent the test tubes from sliding. There are holes on the pipette support plate to allow the tip of the pipette to pass through and play a fixed role. The pipette support plate can be removed for sterilization, and the liquid collection tank located at the bottom of it is a movable part that can be drawn out to collect the pipette. The remaining liquid on the tube can be removed separately for sterilization. The holes on the top plate and the pallet can be increased or decreased as required, and the colored vertical partitions can use different colors. the
