Description
Technical field
The present invention relates to adopt the simple glass centrifuge tube to realize the mechanism of solid-liquid high-speed centrifugation.
Background technology
In modern industry, centrifugal separation technology is more and more important.Centrifugation is by means of centrifugal force, the method that the different material of proportion is separated.The operation principle of centrifuge then is to utilize it to rotate produced several thousand times at a high speed to the centrifugal action power of terrestrial gravitation acceleration, makes the different material of proportion because suffered centrifugal force difference, the sinking speed difference, thus from liquid, separate.According to the difference of centrifugal speed, centrifuge can be divided into: normal speed centrifuge, supercentrifuge and ultrahigh speed centrifuge.Normal speed centrifuge is called low speed centrifuge again, and its maximum (top) speed is in 8000rpm; The rotating speed of supercentrifuge is 10000-25000rpm.
Material in the liquid can be divided into by its size: suspension, colloid and dissolved matter.For solids not molten in the liquid is separated rapidly, adopt centrifugation method usually, solids is gathered on centrifuge tube bottom or the madial wall.Because under low centrifugal rotational speed condition, the solid particle that quality is very little can not be come out by centrifugation fully, so need higher centrifugal rotational speed (more than the general 10000rpm) usually.But, when centrifugal rotational speed is higher than 5000rpm,, place the simple glass centrifuge tube of centrifuge angle rotor to break because the strength of materials is not enough for common glass centrifuge tube.For this reason, external employing safety glass centrifuge tube or Teflon material centrifuge tube usually, but the price of safety glass centrifuge tube is expensive, is the hundred times of simple glass centrifuge tube; The molding of Teflon material is trouble, and price is more expensive, and organic wall built-up effect has also been limited its range of application.
In research and production application, usually run into the problem that the organic matter high speed centrifugation separates in the liquid.For avoiding organic wall built-up effect, the safety glass centrifuge tube is preferably adopted in its centrifugation.Generally speaking, domestic researcher can't adopt the safety glass centrifuge tube, and the simple glass centrifuge tube is not difficult to organic matter is separated fully owing to limited by experiment condition and funds owing to reaching higher centrifugal rotational speed.Organic high speed centrifugation is separated normal employing plastic centrifuge tube, but plastic centrifuge tube there is stronger suction-operated to organic matter.Some scholar rule of thumb by measuring plastic centrifuge tube to organic adsorbance (empirical value), revises because the error that absorption (wall built-up) effect of centrifuge tube produces experiment.Yet plastic centrifuge tube is inequality to different organic adsorbances; Even for same organic matter, when organic substrate concentration not simultaneously, adsorbance also is inequality.So adopt this method experimentation very numerous and diverse, and the content of organics that records is inaccurate, human error and random error are bigger.In addition, the somebody carries out organic centrifugation by the plastic centrifuge tube that will adsorb after saturated, and this method is same numerous and diverse and resultant error is bigger.Thereby it is a problem that bothers that the especially organic high speed centrifugation of the solids in the liquid separates, and receives many scholars' concern.
Summary of the invention
The objective of the invention is, the defective of, solid-liquid high-speed centrifugation difficulty low at the simple glass centrifuge tube strength of materials, a kind of mechanism that adopts the simple glass centrifuge tube to realize the solid-liquid high-speed centrifugation is proposed, it can reduce the cost of centrifuge tube greatly, can reduce human error and the random error of using plastic centrifuge tube instead of glass centrifuge tube to be produced in the centrifugal process simultaneously; Compared with prior art, have advantages such as the cost of material is low, making is easy, easy to use.
Technical scheme of the present invention is; described employing simple glass centrifuge tube realizes that the mechanism of solid-liquid high-speed centrifugation is; it has the eccentric angle rotor of centrifuge, and its design feature is, places the body of the simple glass centrifuge tube of this eccentric angle rotor to be with the rubber protective casing of particular design outward.
Below the present invention made further specify.
Referring to Fig. 1; the present invention adopts the simple glass centrifuge tube to realize that the mechanism of solid-liquid high-speed centrifugation is; it has the eccentric angle rotor 1 of centrifuge, and its design feature is to place the body of the simple glass centrifuge tube 3 of this eccentric angle rotor 1 to be with rubber protective casing 2 outward.
Further structure of the present invention is, as shown in Figures 2 and 3, because the effect of vacuum, after centrifugation was finished, rubber protective casing 2 was often inhaled in centrifuge angle rotor 1, and simple glass centrifuge tube 3 is often inhaled rubber protective casing 2 in and is difficult to taking-up.In order to overcome this difficulty, can offer axial pass trough 5 in the tube wall outside of rubber protective casing 2 symmetry, the bottom plug 4 of band through hole 7 also can be set, bottom plug 4 removable and taking-ups in the bottom of rubber protective casing 2.
Among the present invention, used rubber protective casing 2 should be consistent with centrifuge angle rotor 1 coupling, and the quality of each rubber protective casing is identical, to guarantee rotating shaft bilateral symmetry balance when centrifugal; The rubber protective casing should select the rubber wear-resisting, that physical characteristic is more stable to make, and also can adopt other softer macromolecule organic material.
The present invention is evenly distributed the internal force of simple glass centrifuge tube owing to adopted the rubber protective casing, and the tolerance intensity of simple glass centrifuge tube improves greatly, thereby the centrifugal rotational speed of simple glass centrifuge tube is increased to more than the 15000rpm from 5000rpm; And the simple glass centrifuge tube is with low cost, can guarantee the high accuracy of analyzing and testing again.
As known from the above, the present invention realizes the mechanism of solid-liquid high-speed centrifugation for adopting the simple glass centrifuge tube, owing to adopt the simple glass centrifuge tube, reduce the cost of centrifuge tube greatly, can reduce to adopt simultaneously human error and the random error that is produced in the plastic centrifuge tube separation of organic substances process; Compared with prior art, have advantages such as the cost of material is low, making is easy, easy to use.
