Microcentrifuge tubes are small centrifuge tubes, also known as EP (eppendorf) tubes, often used in conjunction with microcentrifuges for the separation of micro-reagents. The EP tube is an experimental consumable used in molecular biology micromanipulation experiments. In the process of extracting nucleic acid using the magnetic bead method, it is necessary to place an EP tube on a magnetic rack, adsorb the magnetic beads, and wash the magnetic beads. In general, it is necessary to open the lid of the EP tube for reagent addition and disposal. After the reagent is added, the top of the EP pipe is held, the EP pipe is taken out from the magnetic rack, and vibration and uniform mixing are carried out.

The existing situation is: since the EP tube is not firmly fixed to the magnetic frame, vibration of the EP tube is caused when the cover of the EP tube is opened, resulting in splashing of liquid in the tube and contamination between samples. Therefore, in a specific operation, an operator often presses the lower half part of the EP tube by hand and then opens the tube cover, but in this way, the temperature of the reagent in the tube is easily increased due to the temperature of the hand, so that the experiment is affected. In addition, when the EP pipe is taken out from the magnetic frame, the top of the EP pipe is required to be held, and the EP pipe cover is easy to be opened carelessly, so that pollution is caused. In the process of taking out the EP pipe, because the EP pipe is not inseparable with the magnetic rack laminating, the EP pipe rocks and can lead to the scattering of magnetic bead, causes the influence to the experiment.

Detailed Description

The utility model is further described below with reference to the examples and figures 1 to 5.

The utility model provides a magnetic force frame, includes main part frame 1 and mount 2, the mount is used for installing on the main part frame, a plurality of fixed orificess 3 have been seted up on the mount for place EP pipe 9. In this embodiment, the fixing frame is provided with two rows of fixing holes 3, and the two rows of fixing holes 3 are respectively distributed on two sides of the main body frame 1. The middle part of mount 2 is provided with mounting hole 4, and the mounting hole is seted up on a erection column, the erection column can insert on main part frame 1 to play the fixed effect of connection between main part frame 1 and the mount 2.
