Abstract
The utility model discloses a micro centrifuge tube for collecting low-density liquid. The micro centrifuge tube for collecting the low-density liquid comprises a tube body and a cone-shaped tube bottom. The upper portion of the tube body is connected with a liquid-absorbing tube. The shoulder portion of the tube body is provided with a side tube communicated with the tube body. The side tube extends to the middle of the tube body or the lower portion of the tube body, and is at the same horizontal height with the top of the liquid-absorbing tube. The diameter of the liquid-absorbing tube is smaller than that of the tube body. The shoulder portion of the tube body is cone-shaped. Liquid is added from the side tube so as to raise a liquid level in the centrifuge tube, the height of samples to be collected in the tube is increased through changes of pipe diameters, lower-layer liquid is prevented from being absorbed, and pollution of the samples to be collected is avoided. The samples are collected, the amount of remaining samples and loss of the samples to be collected are reduced, and therefore acquisition rates of the samples to be collected and work efficiency are greatly improved.
Description
Technical field
The utility model relates to centrifuge tube, especially a kind of microcentrifugal tube of collecting low density liquid.
Background technology
Centrifugal separation technology extensively should have in fields such as chemistry, biology and medical science, is mainly used in separation and the preparation of various samples.Be contained in sample suspension in the centrifuge tube under rotation at a high speed because huge centrifugal action, make the molecule of suspension or drop with certain velocity sedimentation at the bottom of the centrifuge tube, thereby separated with solution.
General centrifuge tube is that the bottom is taper shape, and top is columniform container.Centrifugalled sample collection is in comparatively narrow conical tip, upper solution by inclining, perhaps use suction pipe, syringe or glass injector to collect lower floor's solution, sample after can obtaining to separate, by another phase liquid contamination, often can not exhaust required liquid fully for fear of the liquid of drawing.Desire is collected the less and volume of the density of solution more after a little while in sample substrate, and through after the centrifugation, desire is collected solution and is tiled in the centrifuge tube upper strata, because height of liquid layer is very little, when collecting supernatant liquid, lower floor's liquid is easy to sneak into, and causes sample contaminated.
The utility model content
The technical problems to be solved in the utility model provides a kind of microcentrifugal tube of collecting low density liquid, make desire collect the liquid level rising of sample by add liquid from side pipe, variation by caliber makes desire collect the height increase of sample in pipe, prevent from drawing lower floor's liquid, avoided desire is collected the pollution of sample; The remaining sample amount reduces when collecting sample, has reduced the loss that desire is collected sample, has improved yield and operating efficiency that desire is collected sample greatly.
Technical solution adopted in the utility model is:
A kind of microcentrifugal tube of collecting low density liquid, comprise at the bottom of pipe shaft and the conical tube that the top of pipe shaft connects pipette, the shoulder of pipe shaft is provided with the side pipe that is communicated with pipe shaft, side pipe extends to middle part or the middle and lower part of pipe shaft, and side pipe and pipette top are in same level height.
The diameter of pipette is less than the diameter of pipe shaft.
The shoulder of pipe shaft is conical.
The shape at the pipe end is consistent with general centrifuge tube, adopts at the bottom of the conical tube, to adapt to the design of centrifuge, can be placed in the centrifuge rotor of corresponding size.
The beneficial effect that adopts technique scheme to produce is:
1. the utility model increases side pipe and pipette at centrifuge tube, by add liquid from side pipe liquid level is risen, and the variation by caliber makes desire collect the height of sample in pipe to be increased, effectively prevent from drawing lower floor's liquid, avoided the pollution to desire collection sample; The remaining sample amount reduces when collecting sample, has reduced the loss that desire is collected sample, has improved yield and operating efficiency that desire is collected sample greatly.
2. the utility model is simple in structure, and is easy to use, has excellent generalization values.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
1, pipe shaft; 2, the pipe end; 3, side pipe; 4, pipette.
The specific embodiment
As shown in Figure 1, a kind of microcentrifugal tube of collecting low density liquid, comprise at the bottom of pipe shaft 1 and the conical tube 2, the top of pipe shaft 1 connects pipette 4, the shoulder of pipe shaft 1 is provided with the side pipe 3 that is communicated with pipe shaft 1, side pipe 3 extends to middle part or the middle and lower part of pipe shaft 1, and side pipe 3 and pipette 4 tops are in same level height.
The diameter of pipette 4 is less than the diameter of pipe shaft 1.
The shoulder of pipe shaft 1 is conical.
After the centrifugal end, collect the solution of sample greater than desire from side pipe 3 injection water or color density with syringe or glass injector, make liquid level in the microcentrifugal tube rise to the shoulder of pipe shaft 1, suction pipe, syringe or glass injector are stretched into from the pipette 4 on pipe shaft 1 top collect sample in the microcentrifugal tube.
When the sample total amount of remaining sample amount very pettiness or desire collection is extremely small, can slowly inject water or color density are collected sample greater than desire solution from side pipe 3, make the interior liquid level of microcentrifugal tube rise to pipette 4, and then carry out the collection of sample with suction pipe, syringe or glass injector.
