4results about How to "Improve centrifugation efficiency" patented technology

The application provides a centrifugal platform and a centrifugal device, and belongs to the field of centrifugation, wherein the centrifugal platform comprises a platform body, a sample inlet, a sample outlet, a sample transfer module, an adapter management unit and a centrifuge site arranged on the platform body, the adapter management unit comprises a bearing platform and an adapter translation module, the bearing platform is provided with N bearing channels for bearing centrifugal adapters, and a first bearing site, a second bearing site and a third bearing site are sequentially arranged in each bearing channel; the adapter translation module is used for translating an empty centrifugal adapter on the second bearing site to the first bearing site and translating a centrifuged adapter on the third bearing site to the second bearing site, so that automatic translation of the centrifugal adapter can be realized, and the centrifugal requirement of a large number of samples can be met.

The utility model relates to the technical fields of kit, put forward a kind of mRNA in vitro transcription kit, kit inside is separated into storage cavity and refrigeration cavity by partition, the refrigeration cavity inside is equipped with refrigeration device, the storage cavity inside includes the support seat fixed in the upper portion of partition, rotatable connection has the rotating shaft of vertical arrangement on the support seat, the top of rotating shaft coaxially is fixed with the rack for placing reagent tube for placing, driving hole is opened along the axis in the rack, the driving hole passes through rotating shaft and extends to the inside of support seat, spiral rod is passed in the inside of driving hole, the driving hole is located on the inner wall of rack and is opened with the spiral groove of the appearance matching of spiral rod. The utility model has the beneficial effects that: using spiral rod and refrigeration device, RNA polymerase can be centrifuged in kit, wait for use, do not need to take reagent out of box again, reduce the risk of temperature rise enzyme activity decline.

The utility model belongs to the technical field of explosion -proof centrifuge, and disclose a kind of explosion -proof flat plate hanging bag type centrifuge, including cylinder, the inside fixed setting of cylinder is provided with fixed column, the inside fixed setting of fixed column is provided with, the outside of the described is provided with power component, the power component includes motor fixedly set in bottom, the main shaft outside fixed setting of motor is provided with rotary disc, the top surface of rotary disc is provided with multiple arc grooves, arc groove's inside movably provided with movable shaft, the bottom surface fixed setting of movable shaft is provided with connecting shaft, and connecting shaft penetrates fixed column, by above -mentioned scheme, it has solved the problem that hanging bag is caused with centrifuge inside gap and leads to dynamic unbalance, improved the safety of centrifugal force when using, protected its internal components, also improved the efficiency of centrifugation, indirectly reduced economic loss.

The utility model belongs to nanometer material recovery technical field, concretely relates to a kind of processing system of superfine metal powder from liquid phase recovery. The processing system includes homogeneous pool, concentration tank, ultrafiltration filtering device, centrifugal device. In the processing system provided in the utility model, mother liquor enters concentration tank after being pumped into ultrafiltration filtering device by first circulating pump and is treated, and concentrated solution containing metal powder is returned to concentration tank, so the concentration of metal powder in concentration tank is constantly increasing, when reaching a certain degree, liquid in concentration tank enters centrifugal device and is separated to obtain metal powder and centrifugal clear liquid, the recovery rate of superfine metal powder in liquid phase is ≧99%, and only ultrafiltration filtering is discharged in the whole process Permeate, and the total silver content of permeate is ≦0.1mg / L, water recovery rate is ≧99%, compared with natural sedimentation or other filtration+drying recovery method, metal recovery rate is high, and the efficiency of centrifugal separation is higher, and operating cost is lower.
