The top of the collecting hopper 12 is open.

When the pipette is used, the dropper of the pipette is downward and passes through the first through hole 21 of the orifice plate 2, and the pipette is set in the first through hole 21 by the expansion part of the pipette, so that the pipette can be set on the pipette rack. The pipette gun is placed on the pipette stand by placing the pipette gun from the mounting notch 31 with the dropper facing downward and hanging the pipette gun on the mounting notch 31 at a position where the overall dimension of the pipette gun is large. The liquid collecting hopper 12 on the base 11 can be used for collecting liquid for experiments falling from the liquid transferring gun and placing a pollution experiment table or corroding the base 11. With this, a pipette and a pipette gun can be placed on the pipette rack at the same time.

Further, in order to facilitate the placement of pipettes of various types, the top of the plurality of support plates 13 is provided with an inclined surface, the plurality of well plates 2 are provided, and the plurality of well plates 2 are arranged in a step shape and detachably connected to the inclined surface of the support plate 13.

Be equipped with the first through-hole 21 of different internal diameters size on different orifice plates 2 to make the pipette of different models size can place on this pipette, a plurality of orifice plates 2 distribute with the echelonment, can make the inflation portion of the pipette on the orifice plate 2 stagger, reduce this pipette and put up the occupation space on the width direction, simultaneously, the pipette length of different models is inconsistent, a plurality of orifice plates 2 are the echelonment and arrange, can provide different height space for the pipette of different length and place.

Specifically, the second through hole 41 and the first through hole 21 are coaxially arranged. In use, the pipette is placed on the well plate 2 by the enlarged portion in a state in which the dropper is directed downward, passing through the first through-hole 21 and the second through-hole 41. For convenient placement, the inner diameter of the first through hole 21 is larger than the outer diameter of the slender tube part of the pipette, but the pipette may shake under the influence of external force during transportation, and the pipette is broken by collision, so that the limiting plate 4 is arranged, and the second through hole 41 is used for limiting the moving space of the pipette to prevent shaking. The inner diameters of the second through holes 41 are larger than that of the first through holes 21, and the top edges of the second through holes 41 are chamfered so that pipettes can be inserted into the second through holes 41 conveniently.

Further, in order to collect liquid dropping from the pipette, the pipette rack further comprises a guide plate 5, wherein the guide plate 5 is tiltably arranged on the support plate 13 and is arranged below the limit plate 4, and the bottom of the guide plate 5 is arranged close to the liquid collecting hopper 12; the guide plate 5 is provided with a plurality of guide grooves 51 in an arrayed manner, the guide grooves 51 incline downwards along the guide plate 5, and the bottom ends of the guide grooves 51 penetrate through the side surface of the guide plate 5.

Specifically, the bottom of the guiding groove 51 is located above the collecting groove, and the guiding groove 51 is opposite to the bottom of each second through hole 41. The diversion trench 51 can collect waste liquid dripping from the pipette, and the waste liquid flows down along the diversion trench 51 and finally drips from the bottom of the diversion plate 5 into the liquid collecting hopper 12.

Further, in order to facilitate installation of the baffle 5, the baffle 5 is provided with a boss 52, the support plate 13 is provided with a sliding groove 132 corresponding to the boss 52, and the baffle 5 can be installed on the support plate 13 by sliding the boss 52 into the sliding groove 132.

Specifically, the length direction of the boss 52 is the same as the length direction of the guide plate 5, and there are two bosses 52 symmetrically disposed on both sides of the guide plate 5, two symmetrical sliding grooves 132 are disposed on two opposite side surfaces of the two support plates 13, one end of the sliding groove 132 away from the liquid collecting hopper 12 is inclined upward and penetrated, the bosses 52 on both sides of the guide plate 5 are aligned one by one with the open ends of the sliding grooves 132 on the two support plates 13 and slide in, so that the guide plate 5 can be installed between the two support plates 13 in a manner of being inclined toward the liquid collecting hopper 12.

Furthermore, in order to facilitate dumping the waste liquid, two ends of the liquid collecting hopper 12 are rotatably mounted on the base 11, one end of the liquid collecting hopper 12 is provided with a convex block 121, the base 11 is provided with a through arc-shaped rotating groove 111 corresponding to the convex block 121, the convex block 121 can pass through the rotating groove 111 and slide along the rotating groove 111, and the convex block 121 is pulled to enable the liquid collecting hopper 12 to rotate relative to the rotating shaft.

Specifically, because the opening of the liquid collecting hopper 12 faces upwards in the using process so as to collect the waste liquid, after a certain amount of waste liquid is collected in the liquid collecting hopper 12, the waste liquid needs to be poured. If collection hopper 12 is fixed to be set up, then empty the in-process of waste liquid, just need take off all pipettes and the pipetting gun that prevent on this pipetting frame, then empty whole pipetting frame, so operate very inconvenient. The bucket 12 is rotatably connected and its rotation is controlled by the projection 121. When the opening of the collecting bucket 12 is upward, the lug 121 is positioned at one end of the rotating groove 111. When the waste liquid is dumped to needs, only need be close to regions such as basin with this pipet stand, stir the lug 121 to the other end along rotating groove 111 then, can make collection hopper 12 rotate the slope, pour the waste liquid of inside. The liquid collecting bucket 12 and the base 11 should be connected in a damping rotation mode, so that the phenomenon that the liquid collecting bucket 12 rotates without any reason and internal waste liquid is poured out by mistake to cause pollution or experimental accidents is prevented.

Further, in order to prevent the pipette from falling off the mounting notch 31, the pipette holder further comprises an elastic member 6, the elastic stopper comprises a connecting portion 61 and an elastic portion 62, the connecting portion 61 is detachably connected to one side of the mounting notch 31, the elastic portion 62 extends into the mounting notch 31, the elastic portion 62 is pressed, and the elastic portion 62 can be drawn towards the connecting portion 61 and can be withdrawn from the mounting notch 31.

Specifically, the connecting portion 61 and the elastic portion 62 of the elastic member 6 are connected to each other, and the entire structure is "V" shaped. A protruding button block 63 is arranged at the joint of the connecting part 61 and the elastic part 62, and the head of the button block 63 is expanded. Two sides of each erection notch 31 are provided with a mounting through hole 32 and two limit protrusions 33121. The knob block 63 is pushed into the mounting through hole 32 and prevented from falling off by the enlarged part, the connecting part 61 is arranged between the two limit lugs 33121, and the elastic part 62 extends into the mounting gap 31, so that the mounting of the elastic member 6 is completed. The elastic member 6 is preferably made of rubber or silicone rubber having good elasticity.

When the liquid transferring gun is used, the liquid transferring gun is placed into the erecting notch 31, the liquid transferring gun extrudes the elastic parts 62 on two sides at the moment, the connecting parts 61 of the elastic parts 62 are closed, the erecting notch 31 is withdrawn, after the liquid transferring gun is placed into the erecting notch 31, the elastic parts 62 are under the action of self elasticity and extend into the erecting notch 31 again, the width of the erecting notch 31 is contracted, and when the liquid transferring gun is shaken or inclined under the action of external force received by the liquid transferring pipe rack, the elastic parts 62 can resist the liquid transferring gun and prevent the liquid transferring gun from sliding out of the erecting notch 31. Each mounting notch 31 is correspondingly provided with two elastic members 6 to make the process more stable.
