Abstract
The utility model belongs to laboratory paraphernalia, is related to a kind of centrifuge tube, including centrifuge tube lid, screen holder and tube body three parts.Screen holder is fixed with centrifuge tube lid by fixed ring and cylindrical bump, and connecting rod controls strainer immersion depth, and 3 connecting rods can remove solidification fat with inboard wall of tube body junction when spiral cover is opened.Strainer has hole, it is ensured that liquid liquid exchanges in centrifugal process, but solidification fat can be hindered to pass through, and reaches removal effect.The utility model is simple and reliable, convenient can remove the upper layer solidification grease formed after high speed refrigerated centrifuge.
Description
Technical field
The utility model belongs to laboratory paraphernalia, be related to a kind of centrifuge tube, more particularly, to it is a kind of with screen holder from
Heart pipe.
Background technology
Centrifuge tube is laboratory common tool, solid-liquid or Liquid liquid Separation process is used for, usually by centrifuge tube lid and tube body two
Part forms, and is fixed by screw thread latch closure.
In general, according to the property difference of test solution to be separated, after centrifugally operated, it is roughly divided into layer 2-3.Possible situation
For：1. supernatant liquor, lower layer's solid；2. upper layer low-density clear liquid, lower layer's high density clear liquid；3. upper layer low-density clear liquid, middle level
High density clear liquid, lower layer's solid；4. upper layer grease, middle level clear liquid, lower layer's solid；5. upper layer grease, subnatant；6. other points
With mode.After to be separated, the modes such as generally use suction pipe, pipette shift or topple over, such mode is when reply pipettes upper layer
It is especially effective.
But everything has special case, when handling the high oil samples such as milk, cosmetics, meat, dilated food, or orientation point
With ether and when high grease aqueous solution, it often will appear upper layer grease solidification phenomenon after high speed refrigerated centrifuge, especially with ether and height oil
The separation of fat aqueous solution becomes apparent.When wanting to remove layer solution, it is difficult to pass through thick and solid solidification grease, it is also difficult to solidify upper layer
Grease completely removes.
Therefore, it is necessary to invent a kind of centrifugation that convenient can be removed the upper layer formed after high speed refrigerated centrifuge and solidify grease
Pipe.
Invention content
The utility model is beneficial in that, can provide a kind of centrifuge tube, can convenient removal high speed refrigerated centrifuge
The upper layer solidification grease formed afterwards.
To realize above-mentioned function, the utility model is related to a kind of centrifuge tube, it is characterised in that：Including centrifuge tube lid (1),
Screen holder (2) and tube body (3) three parts.
Centrifuge tube lid (1) interior central is cylindrical bump (4), has screw thread (5) on the outside of cylindrical bump (4).
Screen holder (2) is made of connecting rod (6), strainer (7) and fixed ring (8).There is screw thread (5) on the inside of fixed ring (8),
It can be fixed with cylindrical bump (4) latch closure.
Strainer (7) and fixed ring (8) are by 3 connecting rod being evenly distributed (6) parallel fixation, and strainer (7) is Round Porous
Plate, diameter are identical as tube body (3) interior diameter.
Connecting rod (6) length is 1/2-3/4 tube body height, is connect with strainer (7) acute angle.
Advantageous effect：The utility model is related to a kind of centrifuge tube, screen holder is fixed with centrifuge tube lid, and strainer can control to immerse
Depth, and 3 connecting rods can remove solidification fat with inboard wall of tube body junction when spiral cover is opened.Strainer has hole, it is ensured that
Liquid liquid exchanges in centrifugal process, but solidification fat can be hindered to pass through, and reaches removal effect.The utility model can be convenient as a result,
The upper layer solidification grease formed after removal high speed refrigerated centrifuge.

Wherein：1. centrifuge tube lid；2. screen holder；3. tube body；4. cylindrical bump；5. screw thread；6. connecting rod；7. strainer；
8. fixed ring；
Specific implementation mode
Embodiment one
In use, the cylindrical bump latch closure that screen holder is covered by fixed ring with centrifuge tube is fixed, screen holder is hung down
Disposed upright enters in tube body, immerses in solution, lid lid.
After high speed refrigerated centrifuge, centrifuge tube lid is unscrewed, is extracted vertically upward, upper layer solidification layer will be completely stripped.It is logical
It crosses connecting rod to screw, screen holder is covered into dismounting from centrifuge tube.
Above-described embodiment is only for illustration of the utility model, and is not the limitation to the utility model patent；It should
, it is noted that for those of ordinary skill in the art, in the case where not departing from the utility model conception range, can also make
Go out various change and modification, these belong to the scope of protection of the utility model；Therefore, all with the utility model claims model
Done equivalent changes and modifications are enclosed, the coverage area of the utility model claims should all be belonged to.
