The variation of air pressure and deform；The bottom of jacket layer is equipped with holder, and holder is the cylindric knot for the upper end opening being threadedly coupled with jacket layer
Structure, bottom are equipped with sucker, can be by screw thread come the height of adjusting bracket because centrifugation bottom of the tube is mostly that taper is unfavorable for placing
Degree, the problems such as increasing suction when placing by sucker, avoid the liquid leakage caused by centrifuge tube is horizontal.
Further, the pipe lid is covered or is threadedly coupled with the clamping of the top of tube body, lid, and connection is more secured.
Further, the centrifuge tube volume is 0.2ml-500ml, and the centrifuge tube of co-content can be mating not different size of
Jacket layer, to adapt to the use of centrifuge.
Further, it is equipped with sealing ring at the stomata, plays sealing effect, temperature is avoided to transmit.
Further, the fastened layer is inflating rubber layer, and top is equipped with air-filled pore, plug is equipped at air-filled pore.
Further, the plug at stomata is threadedly coupled with the plug of stomata and/or inflating rubber layer with air-filled pore, is played
Sealing effect avoids gas from transmitting.
Further, it filled with hot-air or cold air in the interlayer of the jacket layer, or vacuumizes, realizes the guarantor of liquid to be separated
Temperature/cold insulation.
Further, the outer wall of the jacket layer is equipped with the fixing groove to match with centrifuge, convenient for fixing.
Specific operation process is as follows：
When temperature being needed to control, first inflating rubber layer is deflated or directly jacket layer is sleeved on outside centrifuge tube, then to rubber layer
Inflation, fixed jacket layer and centrifuge tube inject heat preservation/cold insulation gas by stomata then according to the requirement of liquid to be separated into interlayer
Body vacuumizes, and to realize heat preservation/cold insulation of liquid to be separated, blocks plug, is centrifuged, do not need temperature control
Shi Ze removes jacket layer without processing after centrifugation, jacket layer is repeatable to be utilized, and cost is saved.
The utility model has the advantage of：By design detachably can inflation/deflation gas interlayer layer, stomata can be passed through
Heat preservation/cold insulation gas is injected into interlayer or is vacuumized, to realize heat preservation/cold insulation of liquid to be separated, while can be to avoid air pressure
Influence cause the tube wall deformation of centrifuge tube, it is applied widely；It with holder and sucker, places, avoids vertically convenient for centrifuge tube
Caused by centrifuge tube is horizontal the problems such as liquid leakage；Dismountable structure, jacket layer is repeatable to be utilized, and cost is saved.
