Description

Gun head box

Technical Field

The utility model belongs to the technical field of medical laboratory instruments, and particularly relates to a gun head box.

Background

At present, the main body structure of a common gun head box is a box cover, a box bottom and a middle support partition plate, one gun head box is only matched with and fixed with one partition plate, a plurality of far through round holes are uniformly distributed on the partition plate and used for inserting a pipette head, and the gun head box can only contain the gun head of one type.

In biochemical, molecular or cellular experiments, the number of pipette tips of different types used by experimenters may vary greatly, i.e., there is a problem that the number of tips used in different specifications is not balanced. Taking a molecular experiment as an example, when the plasmid is extracted by the plasmid miniextraction kit, 1mL of gun heads with the specification are mainly consumed, the required amount of 200 mugs is small, and about 1/5 mugs are consumed only when 1mL of gun heads are consumed. In order to save the energy consumption of sterilization, the gun head box is generally filled with the gun heads as much as possible and then sterilized, and the gun heads are placed in the sterilized instrument consumable for the longest time (5-7 days), but even if the gun heads with different specifications are not used, the bearing number is fixed, and the phenomenon that the gun heads are not used but the placing time exceeds the requirement and needs to be sterilized again can be caused; moreover, in order to prevent cross contamination, sometimes one experiment is completed, and when the next experiment is carried out, a new undetached gun head is often required to be replaced for use, which is more obvious in microorganism and cell experiments. These result in that different numbers of unused tips are left in the tip box and the tips are required to be sterilized again, wherein the tip box with the 10 μ L specification is particularly serious, and the waste of manpower and energy is caused when most of the tips are left and the tips are required to be sterilized again. It is therefore necessary to design a magazine of tips which can be assembled according to the number and type of tips required for the actual test.
