Detailed Description
As shown in fig. 1, the centrifugal tube fast balancing device of the present invention comprises a horizontal base formed by arranging a plurality of digital display electronic scales 1 with the same structure in parallel, wherein weighing surfaces on the top of the digital display electronic scales 1 together form the top surface of a horizontal flat base; the automatic balancing device is characterized in that a power main switch 2 and an external power line 3 which are used for controlling the digital display electronic scales 1 to be opened are arranged on the horizontal base, a digital display screen 4 and a zero control key 5 are arranged on the front side wall of each digital display electronic scale 1, the weight of a centrifugal tube arranged on the digital display electronic scale 1 is weighed, and then the rapid balancing of sample solution is completed.
A supporting part is longitudinally fixed on the side wall of the horizontal base, and a centrifugal tube clamping part is fixedly connected on the supporting part above the horizontal base; concretely, this supporting part is for being fixed in the horizontal base left side, four groups of longitudinal extension pole 6 on the wall of the right side, this centrifuging tube clamps the portion and links firmly horizontal cardboard 7 with the flexible end of four groups of longitudinal extension pole 6 respectively for the four corners, the centrifuging tube card hole 8 with 1 one-to-one of digital display electronic scale is seted up at the interval on horizontal cardboard 7, be used for clamping the centrifuging tube, make the centrifuging tube bottom surface laminating of card in this centrifuging tube card hole 8 press admittedly on the weighing surface at 1 top of digital display electronic scale, ensure simultaneously that the centrifuging tube can not rock at the weighing in-process centrifuging tube.
In order to adapt to the centrifuge tubes of various models, an annular clamping table 9 for adjusting the aperture size can be movably clamped in each centrifuge tube clamping hole 8. In addition, because the tube caps of some centrifuge tubes are not connected with the tube body, for the accuracy of weighing, four groups of longitudinal telescopic rods 6 are arranged close to the rear side of the horizontal base, the tube cap placing marks 10 which are in one-to-one correspondence with the digital display electronic scales 1 are arranged on the top surface of the horizontal base which is positioned at the front side of the horizontal clamping plate 7, namely, the tube cap placing marks 10 are arranged on the weighing surface at the top of each digital display electronic scale 1 close to the front side, so that the corresponding placement of each centrifuge tube cap is facilitated.
When the device is used, the device is placed on a horizontal experiment table board, the external power line 3 is inserted, the power main switch 2 is turned on to preheat the digital display electronic scale 1 for more than 30min (because the digital display electronic scale 1 belongs to electronic precision equipment, the electronic precision equipment generally needs to be preheated for 30-60 min before use, the purpose is to ensure the accuracy of data), the height of the longitudinal telescopic rod 6 is adjusted according to the height of a centrifugal tube to be measured, and the bottom of the centrifugal tube can be attached to a weighing surface at the top of the digital display electronic scale 1 when the centrifugal tube is placed in a centrifugal tube clamping hole 8, so that the centrifugal tube can be weighed by the digital display electronic scale 1; then, pressing a zeroing control key 5 to zero all the digital display electronic scales 1, simultaneously opening the centrifuge tubes and placing the centrifuge tubes into centrifuge tube clamping holes 8 one by one, placing the opened tube covers on corresponding tube cover placing marks 10, and displaying the weight of the empty centrifuge tubes and the tube covers on the digital display screen 4; then, the sample solution to be centrifuged can be subpackaged into a centrifugal tube, and fine adjustment is carried out according to the real-time displayed numerical value on the digital display screen 4, so that equal subpackage is ensured; and after the split charging is finished, the tube cover can be buckled, and the split-charged centrifuge tube is taken down for subsequent centrifugal operation.
