Abstract
The utility model discloses a kind of centrifuge shields with a scale, are made of inner and outer tubes, which is characterized in that the outer tube is set in outside inner tube, is formed a closed collet between inner and outer tubes, is filled with counterweight liquid in the collet；The outer tube top is also provided with inlet, and outer pipe bottom offers liquid outlet, and outer tube wall is equipped with the metering scale as unit of quality and the mass metrology scale by being arranged on tube body；It by the way that collet is arranged, and is packed into collet and matches heavy-fluid, the trim of centrifuge both sides quality can be completed before carrying out centrifugally operated using centrifuge.
Description
Technical field
The utility model belongs to experiment equipment technical field, and in particular to a kind of casing of centrifuge tube.
Background technique
Centrifuge tube is that common a kind of auxiliary appliance in solid-liquid phase lock out operation is carried out in laboratory, previous centrifuge
Trim adds water centrifuge tube or symmetrically placed sample centrifuge tube identical in quality, the method using symmetrically placed phase homogenous quantities
Not only limited centrifuge centrifugation slot number had been wasted, but also has not been difficult to realize trim simultaneously in sample quality.
Utility model content
What the utility model was implemented aims to overcome that existing deficiency, and providing a kind of can accommodate centrifuge tube and can be placed into
The pipe sleeve of centrifuge eccentric groove, to trim.
The utility model is achieved by the following technical solution:
A kind of centrifuge shield with a scale, is made of inner and outer tubes, and the outer tube is set in outside inner tube, inner tube and outer
A closed collet is formed between pipe, is filled with counterweight liquid in the collet；The outer tube top be also provided with into
Liquid mouth, outer pipe bottom offer liquid outlet, and outer tube wall is equipped with the metering scale as unit of quality.
The distance between described outer wall of inner tube and outer tube wall are 2-6mm.
Inner tube nozzle extension has nozzle protruding portion, and the outer tube is removably arranged on nozzle protruding portion.
Internal screw thread is equipped in the nozzle protruding portion, outer tube top is equipped with the external screw thread with the screw-internal thread fit, outer tube
It is arranged on nozzle protruding portion by screw thread.
The inlet and liquid outlet is the notch being provided on outer tube wall, is equipped on inlet and liquid outlet
Plug.
The outer surface of the plug and the curve form of outer tube outer wall are identical and be located in the same cambered surface with outer tube.
The counterweight liquid is water, alcohol or the preferable liquid of other mobility.
Using the above-mentioned centrifuge shield of the utility model, counterweight liquid is added into centrifuge shield, and by setting on tube body
The mass metrology scale set, thus being operated with equality before realizing centrifugation.
Compared with prior art, the utility model has the following beneficial effects: 1, by setting collet, realize when needing to be centrifuged
When sample quality is inconsistent, it by being packed into counterweight liquid in set folder can make that centrifuge two can be completed before centrifugally operated
The trim of side quality；2, by being arranged on outer tube wall by metering scale as unit of quality, experimenter is enabled to
The quality with heavy-fluid being added intuitively is known very much, to realize the trim of centrifuge tube；3, the inlet of the utility model and
Liquid outlet is the notch being provided on outer tube wall, is equipped with plug on inlet and liquid outlet, the outer surface of plug and outer
The curve form of pipe outer wall is identical and is located in the same cambered surface with outer tube, not the outer shape of the original centrifuge tube of capping, no
Any influence can be brought to centrifugally operated；4, the outer tube of the utility model is removably arranged in outside inner tube, easy to clean and real
With；5, the utility model also has the features such as simple structure and reasonable design, easy to use, uses the concentrator bowl of the utility model
Pipe can not carry out the defect of centrifugally operated, greatly when the liquid quality on centrifuge both sides is unequal in very good solution experiment
The efficiency for improving experiment, saved experiment chemical reagent used.
