The purpose of this utility model realizes as follows: this pipet stand relates to bearing, bearing is by the base of middle part band boss and be in pillar vertical on the boss and constitute, at bearing upper support saddle, saddle constitutes by the bottom plate that is parallel to each other separated by a distance and upper backup pad and with the connector that they link together, through hole is arranged in the middle of bottom plate and the upper backup pad, they are enclosed within on the pillar by through hole, the bottom plate bottom supporting on base boss on, saddle can rotate with respect to bearing like this, on upper backup pad, be furnished with the upper support hole of some through holes as pipette, be furnished with the lower support hole corresponding with upper support hole number and horizontal level on bottom plate, the lower support hole is by arc or pyramidal pits and be in the through hole that pit bottom penetrates bottom plate and constitute.The upper support hole can be uniform along several concentric circles, and the distribution form in upper support hole is also followed in the lower support hole.Different sizes can be made to adapt to the difference of pipette specification in the upper support hole, same lower support hole dimension is respective change also, when pipette is placed on the pipet stand, pipette top is in the upper support hole, the lower end of pipette is supported in the corresponding lower support hole, pit by the lower support hole to the pipette lower end to upper support and about the location avoid slippage, if residual in the pipette have liquid, just can flow out downwards by the lower support hole.

In order to prevent that liquid flows out the after stain environment in the pipette, below saddle, design liquid collector.Can consider on plane on the base, to design collecting tank, but fall liquid or need move whole base when cleaning, not too convenient.Reasonable selection is the special independent catch tray that can conveniently move of design, and for this reason, placement is inserted at base boss and is lower than the catch tray of boss height on base.Be the hole than boss slightly larger in diameter in the middle of the catch tray, the border in hole and outmost turns are the shapes of upwards turning up.

When residual liquid goes out by the lower support orifice flow in the pipette; drift about along the bottom plate bottom surface level of production through regular meeting; thereby it is low outside catch tray; for this reason; the drainage ring of inside and outside twice to lower process arranged in the bottom plate bottom surface; the drainage ring is along being on the diametric(al) between catch tray inner ring and the outer ring, and the liquid of horizontal drift can flow down along it after running into the drainage ring, is dropped in the catch tray.

Base and pillar can be overall structure, produce for convenience and transportation, also they can be designed to the branch body structure, patch together during use.Be specially: there is bellmouth at the center of base boss, and the tapering part of pillar lower end is inserted in the bellmouth of boss, and pillar just is fixed together with base like this.

Bottom plate and upper backup pad and connector can be overall structure, for ease of production and transport, also can be designed as the branch body structure, the effect of connector is that bottom plate and upper backup pad are linked together, so connector has multiple version, can be connecting rod, connecting cylinder, connecting plate etc., fixed form also can adopt the heat seal mode of screw connection, bonding, plastics or the welding manner of metal etc.We are the modes of pegging graft with connecting cylinder this introduction: above the bottom plate and upper backup pad below the middle part raised ring is arranged, connector is a tubular, links together by interference fit between this connector two ends endoporus and the raised ring cylindrical.

This pipet stand can make pipette put neatly, picks and places conveniently, can not bump between the pipette, when residual liquid flows out in the pipette special gatherer is arranged, and does not pollute surrounding environment, and it is many to adapt to the pipette specification of depositing.
