Description

Pipette stoving degassing unit

Technical Field

The utility model relates to the technical field of laboratory equipment auxiliary devices, in particular to a pipette drying and sterilizing device.

Background

The pipette is a device frequently used in the working process of a laboratory, and the pipette is required to be cleaned by deionized water after being used. The pipette body is longer, both ends opening is less, need dry in the air for a long time after wasing just can make its inner space dry, and the pipette quantity that the laboratory was equipped is limited, needs to use alternately between some experimental projects, has prolonged latency. In addition, the long-term humidity inside the pipette may cause bacterial growth, thereby contaminating the next use.

The ordinary pipette rack that uses at present can only vertically place the pipette, in actual operation, still need long-time waiting after the pipette rack washs to place, and the pipette just can naturally dry, and this can undoubtedly influence operating personnel's use, has produced certain delay to the work.

To remedy the deficiencies of the prior art, CN 210935091U provides a pipette rack that accelerates pipette drying. Compared with the prior art, the scheme has the advantages that the fan is additionally arranged in the chassis, so that the drying speed of the pipette after cleaning can be improved. However, since the pipette is vertically placed on the pipette rack, moisture in the pipette flows downwards under the influence of gravity, and the fan is arranged at the bottom, the blown air is vertically upward, opposite to the water flow direction, and the outflow of the moisture in the pipette is not facilitated, so that the practicability is poor.

CN 210230016U discloses a pipette rack, wherein a ventilation device, namely a fan, is arranged in a cavity inside a supporting rod, a plurality of air holes penetrating through the cavity are arranged on the outer side wall of the supporting rod, and air blown out from the ventilation device is discharged through the air holes of the supporting rod, so that air circulation in the space is improved, and drying of a pipette is accelerated. However, the fan is arranged in the support rod and is used for exhausting air through the air holes, so that the resistance is high, the air mobility is low, and the practicability is poor; secondly, the fan is arranged in the support rod, the support rod is small in diameter and difficult to install and realize larger air quantity, and the support rod occupies the space for placing the pipette when the diameter of the support rod is large; in addition, the air blown out of the ventilation device is discharged through the air holes of the support rods, so that the ventilation of the outside of the pipette is only increased, the drying effect on the moisture in the pipette is very limited, and the drying effect in the pipe is poor. In addition, the water catch bowl of this scheme passes through drainage groove drainage, needs to incline whole rack during the drainage, and the operation is inconvenient, has also increased the risk that the pipette drops simultaneously.
