Description

A kind of medical centrifugal

Technical field

The utility model belongs to field of medical article technology, and in particular to a kind of medical centrifugal.

Background technology

In bioscience, particularly biochemistry and molecular biology research field, very extensive application is obtained, often A biochemistry and Molecular Biology Lab will prepare the centrifuge of a variety of patterns.Centrifugation technique is mainly used for various lifes The separation and preparation of object sample, biological sample suspension is contained in centrifuge tube in the case where high speed rotates, due to huge centrifugal force Effect makes the molecule of suspension（Such as precipitation of organelle, large biological molecule）With certain velocity sedimentation, so as to it is molten Liquid is separated.It is frequently necessary to use centrifuge tube in biological scientific experiment, the definition of centrifuge tube is：Tubulose sample container, can With closure or gland.Existing centrifuge tube mounting material classification can be divided into plastic centrifuge tube, glass centrifuge tube, steel centrifugation Pipe.The utility model is improved based on glass centrifuge tube.It is should not be too large using centrifugal force during glass tube, it is necessary to pad rubber Rubber cushion prevents pipe from crushing, and supercentrifuge does not select glass tube generally.Centrifuge tube closed with covers is not good enough, and liquid is just not It can fill it up with（For supercentrifuge and use angle rotor）With anti-overflow, disequilibrium.Excessive consequence is pollution rotor and centrifugation Chamber influences inductor normal work.During ultracentrifugation, liquid has to fill it up with centrifuge tube, because surpassing from pumping high vacuum is needed, only It fills it up with and is just avoided that centrifuge tube deforms.

Since glass centrifuge tube belongs to fragile article, the feelings that glass centrifuge tube crushes often occur in biology laboratory Condition causes the progress for influencing Bioexperiment, while there is also the hidden danger for scratching experimenter's finger.

In view of this, it is necessary to solve the above problems to design a kind of medical centrifugal with pedestal.

Utility model content

The purpose of this utility model is to provide a kind of medical centrifugal, to solve mentioned above in the background art ask Topic.

To achieve the above object, the utility model provides following technical solution：A kind of medical centrifugal, including bottom plate, institute It states substrate and is installed with fixed seat, tube body is placed with inside the fixed seat, is connected at the top of the tube body by external screw thread Upper cover is connected to, graduation mark is equipped with outside the tube body, its bottom is equipped with taper tightening portion, the taper tightening portion bottom Equipped with liquid outlet, the liquid outlet is internally provided with regulating valve, and the taper tightening portion is internally provided with semi-permeable membrane.

Preferably, the bottom base plate is equipped with rubber layer.

Preferably, the upper tops are equipped with anti-skid bulge.

Preferably, the upper cover is internally provided with silica gel sealing pad.

Preferably, the tubular body is equipped with ring rib.

Preferably, one side is equipped with adhesive label outside the tube body.

The technique effect and advantage of the utility model：The medical centrifugal by setting the pedestal to match with tube body, makes It obtains the centrifuge tube and places and stablize, it is not easy to fall, be set by the way that pedestal is fixedly mounted on bottom plate, and in bottom plate upper bottom portion Rubber layer, rubber layer can both play the role of anti-skidding, while also function to cushioning effect so that the utility model is placed and stablized, no It easily falls, has ensured the safety of experimenter, be worthy to be popularized.
