Preferably, the surface of the liquid collecting tank is provided with fold-shaped lines, so that splashing caused by dripping of the reagent from the pasteur pipette is reduced, and cross contamination is avoided when a plurality of pasteur pipettes are placed.

Preferably, the pipette slots are respectively different-sized pipette slots matching the non-volume pasteur pipettes, and a plurality of different-sized pipette slots can be designed for the commonly used commercial 1ml, 2ml, 3ml and 5ml pasteur pipettes to be arranged on the storage table.

Further preferably, the straw grooves with different sizes are sequentially arranged on the upper surface of the table body from large to small or from small to large, so that the arrangement is more regular, and the arrangement errors are reduced.

Further preferably, the storage table may be separated into a plurality of storage units each having a single pipette slot of different volume, the storage units may be connected to each other by a magnet, and the experiment may be performed in different places.

Preferably, the table body is a plastic table body or a metal table body or a ceramic table body, and is made of a material which is not easily corroded by a chemical reagent, so that the service life is prolonged.

Preferably, the table body is a plastic table body, so that the table is light, practical and low in price.

The beneficial effects of the utility model reside in that:

(1) the stable placement of the pasteur pipette can be realized through simple design, and the operating experiment table is not easy to be polluted.

(2) The repeated utilization of the pasteur pipette can be realized, the using amount of the pasteur pipette is reduced, the waste amount of the pasteur pipette is further reduced, and white pollution is reduced.

(3) Convenient use, low cost and high economic feasibility.
