Generally completed using the pipettor of single channel or multichannel.But when carrying out solid-liquor separation or liquid-liquid extraction, using manual
Operation is difficult to precise control liquid-transfering gun pipette tips and is properly inserted the liquid layer to be drawn specified, such as is drawn in liquid-liquid extraction and treat imbibition
Upper phase or lower phase when, due to it is manually operated when deviation, often cause liquid-transfering gun pipette tips stretch into its adjacent liquid layer, cause miss
Inhale.Existing orifice plate sampling height adjustor is generally using fixed liquid-transfering sucker highly, high by adjusting microwell plate or deep-well plates
The mode of degree so that suction nozzle reaches the specified altitude assignment of orifice plate liquid filling hole.In this mode, operator needs to pay close attention to pipettor simultaneously
Or the attitude of liquid-transfering gun and control adjust deep-well plates or porous plate highly, use operation more inconvenient.Also, for 48 holes,
Spacing between the high density holes microwell plate such as 96 holes and 384 holes and deep-well plates, liquid filling hole is minimum, and slight inclination occurs for liquid-transfering gun attitude
When, it can also shine into pipette tips and deviate corresponding aperture, and adjacent hole slot is inhaled by mistake.Also, existing perforated plate sampling height adjustor is using envelope

During the perforated plate sampling height adjustor provided using the present embodiment, selection first is mutually matched with orifice plate 4 to be measured
Porous plate 1 (be wherein mutually matched refer to hole on porous plate 1 and orifice plate 4 to be measured arrangement mode and Kong Yukong it
Between centre-to-centre spacing should be consistent with each other), then porous plate 1 is inserted in the slot 21 on hoistable platform 2, it is ensured that porous plate 1
Corresponded with above and below the hole position on orifice plate 4 to be measured, in the hole position 11 that the pipette tips of liquid-transfering gun 6 are inserted to porous plate, you can regulation
Elevating mechanism 5, adjusts the specified location of suction range liquid level into the hole slot 41 of orifice plate to be measured of the pipette tips of liquid-transfering gun 6, such as two-phase
Phase 412 under phase 411 or two-phase prepare liquid, then fixes the height of elevating mechanism 5 in prepare liquid, and the liquid relief for determine height is grasped
Make.It is important that, it is only necessary to it is orifice plate 4 to be measured that the single adjustment attitude of liquid-transfering gun 6 can be achieved to deep-well plates or porous plate with height
Fixed height is carried out to sample.And due to being Open architecture between hoistable platform 2 and pedestal 3, field range is more broad, can be clear
During descending operation, pipette tips attitudes is observed in real time, and whether whether correct and pipette tips end is located at correct hole slot position
Put, so as to ensure that the pipette tips of liquid-transfering gun 6 are in vertical position all the time, pipette tips can be avoided to insert adjacent hole slot.Due to the present patent application
Device use during, it is single adjustment pipette tips height and attitude, and orifice plate to be measured 4 all the time be in fixed static position, its
It is simple to operate, and the situation for inhaling adjacent hole by mistake can be avoided to occur.
Wherein, the diameter in the hole on porous plate 1 should be less than the diameter of the pipette tips afterbody of liquid-transfering gun 6, to ensure the rifle of liquid-transfering gun 6
Head is not fallen out when passing through porous plate 1, and porous plate 1 can be existing institute with hole arrangement with the hole number on orifice plate 4 to be measured
Any one in the quantity and hole formation system of use, such as 1536 (32 × 48) holes, 384 (16 × 24) holes or 96 (8 × 12)
It is hole in (4 × 3) hole of 24 (6 × 4) hole of hole 48 (8 × 6) hole 12 or 6 (3 × 2) holes, its bracket
The matrix form of arrangement.
Further, elevating mechanism 5 is scissor-type lifting mechanism, guide tracked rack-gear type elevating mechanism, worm and gear
One kind in formula elevating mechanism.Certainly in addition it can also be the elevating mechanism 5 of other structures, as long as lifting can be controlled flat
The level of platform 2 is moved up and down, on use which kind of elevating mechanism 5, the present embodiment is not limited this, specifically optionally and
It is fixed.
Further, a kind of perforated plate sampling height adjustor that second embodiment of the invention is provided, scissor-type liter
