Problems solved by technology

The pickling and water washing of this device have to be divided into two steps, and the number of times of washing is large, the water consumption is large, and the operation time is long. In particular, the process cannot be fully automatic, and the labor intensity of the operator is increased because the washing time is too long.

Embodiment 1

[0027] In this example, see Figure 1~5 , an automatic washing pipette device, which is composed of a container and a liquid flow inlet 1 and a liquid flow outlet 5 installed on the side wall of the container. The container is made of plexiglass transparent material. The section of the container is square. Shaped side wall, base 2 and openable sealing cover 8 enclose to form a box-type washing chamber, the container is formed by a barrel-shaped side wall and base 2 into a tank-shaped container, and a movable pipette is used to fix the mounting plate 6. A series of pipette insertion mounting holes 4 are distributed on the pipette fixing mounting plate 6, so that the tip of the pipette to be washed is installed upside down in the mounting hole 4, and the pipette to be washed can be placed in the mounting hole 4. The pipette is arranged on the pipette fixed mounting plate 6, and also adopts a rubber stopper. When the part of the mounting hole 4 on the pipette fixed mounting plate...

Embodiment 2

[0035] This embodiment is basically the same as Embodiment 1, especially in that:

[0036] In this embodiment, a lotion supply switch valve is provided on the lotion supply pipe 9, and a faucet is used as a source of cleaning water. On and off are controlled separately. This embodiment is also very convenient, can improve cleaning efficiency, is easy to control, and saves power consumption.

Abstract

The invention discloses a device for automatic pipette cleaning, wherein a washing liquid enters the device via a washing liquid storage device; under effects of a decompression suction filtration device, the washing liquid enters a pipette and then flows out; and the thorough cleaning is conducted after repeated operations. The washing liquid flows out and then enters the washing liquid storage device, so that recycling can be implemented; and a switch connected to the washing liquid storage device is switched off, a switch connected to water source supply is switched on, and then washing is conducted for multiple times. The device disclosed by the invention has the advantages that the structure is simple; the semi-automatic cleaning of full-course automatic cleaning can be implemented; the labor cost is reduced; and consumption of water resources can be reduced.

Description

technical field [0001] The invention relates to a cleaning device for experimental equipment, in particular to a washing liquid pipetting device, which is applied in the technical field of chemical experimental equipment. Background technique [0002] Pipette is an indispensable experimental equipment in the analysis laboratory. It is widely used, but because glass equipment needs to be recycled, it will inevitably face a very tedious washing work. At present, the washing of the pipette is usually to hold the acid-treated pipette and rinse it under the tap. This method not only has low washing efficiency, but also is difficult to wash, and the rinse time is too long. reduced the labor intensity of the operator. [0003] The advent of the pipette washer overcomes the inherent shortcomings of the traditional washing method. It not only has a large washing capacity, high work efficiency and good washing effect, but also is especially suitable for washing a large number of pipe...
