Abstract

The invention relates to the field of microorganism experiment instruments, in particular to a pipettor suction nozzle box. The box comprises a box body and a box cover, a bearing part is arranged inthe box body, a plurality of insertion holes are formed in the bearing part, insertion hole covers are arranged at the opening positions of the insertion holes, pipe bodies for containing suction nozzles are arranged in the insertion holes, film holes are formed in the insertion hole covers, and the positions of the film holes are covered with air purification films. According to the product, theinsertion hole covers are arranged at the openings of the pipe bodies by adopting a double-layer locking system, so that the insertion hole covers are effectively prevented from being automatically bounced off during high-pressure steam sterilization, and the cover sealing effect is very reliable. each suction nozzle is provided with an insertion hole cover, and each insertion hole cover is provided with a breathable film, so that the effect of high-pressure steam sterilization is guaranteed, air permeability and moisture permeability are achieved, it can be guaranteed that the suction nozzlesto be used are in a reliable sterile state during operation, and test errors caused by pollution and wetting due to the situation are avoided; and the insertion hole covers can be used repeatedly, sothat the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of microbial experiment instruments, in particular to a pipette nozzle box. Background technique [0002] At present, biochemical, genetic and microbiological laboratories generally use micropipettes to transfer small-capacity liquids, and the micropipettes need to replace the nozzles after each liquid transfer. Therefore, it is often necessary to use more suction nozzles in the test operation, and it is necessary to use various suction nozzles of different specifications. Since the existing pipette nozzle box can only accommodate a nozzle of one specification, multiple nozzle boxes will be used when using multiple specifications of micro-volume nozzles, which is inconvenient to use, and the pipette nozzle box needs to be used when using it. Even if the nozzle box is sterilized, if you take one nozzle, the other nozzles are exposed to the air, and each micropipette nozzle has no protective function, and microorganism...
