Embodiment Construction

[0013] The technical solutions of the present invention are further illustrated in the following examples, but will not limit the scope of the invention.

[0014] like figure 1 As shown, the centrifugal precipitation of the present embodiment includes a handle 4, a motor 3, a telescopic rod 2, and a nylon brush 1, wherein the motor 3 is mounted in the handle 4, and the retractable rod 2 is connected at the lower end of the handle 4, The nylon brush 1 is connected to the tail of the retractable rod 2, and there is a regulating switch 5 on the outer casing of the motor 3, and the upper end surface of the handle 4 is provided with a USB charging port 6. The USB charging port can be charged for a lithium battery built into the handle 4, and the lithium battery is powered. The motor 3 drives the telescopic rod 2 to rotate, and the nylon brush 1 is rotated. Adjusting switch 5 can adjust two gear positions, and the rotational speed is 4000 rpm and 2000 rotation / min. The total length of...

Abstract

The invention discloses a centrifugal precipitation automatic resuspension device and a resuspension method. The resuspension device is composed of an operating rod and a brush, the operating rod comprises a handle, a motor and a connecting rod, the brush is connected with the handle through the connecting rod, the motor is installed in the handle, and the motor drives the connecting rod to rotate so as to drive the brush to rotate. When the resuspension device is used, a solution required by resuspension is added into the centrifugal tube, then the brush of the resuspension device is contacted with the precipitate, and the motor drives the brush to rotate, so that the precipitate is resuspended and uniformly mixed. According to the invention, the problem that a precipitate sample after long-time centrifugation or ultracentrifugation is difficult to resuspend is solved, and the resuspending device not only saves manpower, but also improves the precipitate resuspending efficiency, and can avoid possible pollution to the precipitate sample.

Description

Technical field [0001] The present invention relates to biological experimental operation techniques, and more particularly to a rapid resuscitation and mixing of a method and a small handheld instrument-automatic resuscator for rapid resuscitation. Background technique [0002] Centrifugation is one of the most commonly used operational steps in the biological experiment, often refresses the centrifugation of the biological sample (especially protein extraction purification). If the centrifugation is longer or the centrifugal speed is high, it will make the precipitate after the centrifugation is uniform, and there will be tap-sucking when using a pipette to blow a mix, so that the sample is contaminated, the pipette is damaged and the time is expensive. The document that has already been published has not yet mentioned rapid resuscitation, and the biological equipment in the market also has no related products. Inventive content [0003] It is an object of the present inventio...
