Description

Liquid-transfering gun rack

Technical Field

The utility model relates to a medical equipment technical field especially relates to a liquid-transfering gun rack.

Background

In the scientific research fields of biology, medicine, chemistry and the like, a pipetting gun is generally used for accurately and quantitatively pipetting a small amount or a trace amount of liquid. The liquid-transfering gun belongs to a precise instrument, and needs to be careful when being stored to prevent damage and avoid influencing the measuring range so as to cause inaccurate liquid quantification and influence an experimental result. Therefore, the liquid transfer gun needs to be stored on a specific liquid transfer gun rack, namely, the liquid transfer gun is stored, and the liquid transfer gun is convenient to take and place.

At present, a liquid-transfering gun rack is usually adopted in a laboratory to support a liquid-transfering gun, so that the purpose of storage is realized. The common pipette rack has three types, one is the pipette rack in a Z-shaped bracket shape or an L-shaped bracket shape, a plurality of notches are arranged on the pipette rack, and the pipette is hung on the pipette rack in an inclined shape; secondly, an O-shaped disc-shaped liquid-transfering gun rack is adopted, a plurality of notches are formed in a disc, and the liquid-transfering gun is vertically hung on the disc-shaped liquid-transfering gun rack; and thirdly, the Z-shaped non-notch type liquid-transfering gun rack is characterized in that liquid-transfering guns with different ranges are mutually close to each other and are obliquely placed on a cross rod of the liquid-transfering gun.

The notches (or the notch-free shapes of the third person) on the three liquid-transfering gun frames belong to an open type, the liquid-transfering guns cannot be well clamped by the notches on the liquid-transfering gun frames, so that the liquid-transfering guns are poor in stability when placed, are carelessly touched during experiments, are extremely easy to drop, and cannot be effectively protected, and the accuracy of the liquid-transfering guns is influenced. Meanwhile, the three liquid-transfering gun racks are vertically placed (the cross rod without the buckle is long), and the whole volume is relatively large. Due to the fact that the space on the surface of the experiment table or inside the fume hood is limited, the three liquid gun racks occupy large space, and effectively available space resources are reduced. In addition, a plurality of pipetting guns are put together (no matter place in the notch, still put on the horizontal pole), normally get when putting easy mutual influence to influence staff's experimental operation. Therefore, there is a need for a pipette gun rack having good stability, a small space volume, and a detachable pipette gun.
