Background

The centrifuging tube is plastic products generally, and the tube cap has all been prepared to most centrifuging tube, if the cooperation between tube cap and the centrifuging tube is relatively poor, and is sealed untight, then leads to liquid excessive in the centrifuging tube easily, leaks and corrodes the centrifuge, influences its life, to the liquid that contains volatile composition, still arouses volatile composition easily and loses, produces the influence to each composition content in the centrifuging tube, and then arouses that the experimental result appears the deviation. Therefore, the tube cover and the centrifuge tube should have good sealing performance. At this time, a sealing test, that is, leakage detection, needs to be performed by a sealing tester, for example, an MF-300 type sealing tester provided by oribogaceae is a relatively common instrument. The theory of use of this equipment makes the external environment that the sample was located reach certain vacuum through the evacuation to form certain pressure differential inside and outside the sample, if the leakproofness of sample is relatively poor, its inside gas will spill over from the sample is inside outwards along sealed relatively poor department under the effect of pressure differential, whether have continuous bubble to produce or sample shape recovery condition after releasing the vacuum through observing the sample surface that is in the aquatic and confirm its sealing performance, or also can put down the tube cap in the seal pot bottom down behind centrifugal tube dress water, whether there is liquid to spill over the observation.

However, adopt this instrument to carry out the link of testing at present, generally put centrifugal tube dress water in the bottom of seal pot, or place at will in the seal pot of filling with water, this puts the angle of putting of centrifuging tube when just having led to the test or the tube cap is vertical placing down (when the dress water test liquid spills over the condition), or horizontal in aqueous (during the side gas leakage condition of soaking in water), and its performance of leak degree is different when the centrifuging tube is in different putting the angle, it is unable multiaspect demonstration of centrifuge tube leak degree that just detects the leakproofness of centrifuging tube under vertical angle and horizontal angle.
