Low-speed large-capacity multi-tube centrifuge operation and precautions

In the Earth's gravitational field, any object is subject to gravity of the product of its mass and the acceleration of gravity, and the greater the mass, the greater
the gravity.

In order to increase the separation capacity, people have made centrifuges, when the rotor rotates at high speed, the centrifugal acceleration produced by the high-speed rotation of the rotor is many times the acceleration of gravity, the force is many times that of gravity, the separation capacity is also increased many times, and the precipitation that takes a whole day to complete in the natural shelf state may be completed
in a few hours or less in the centrifuge.

What's more, operations that cannot be separated at all in the naturally stranded state can be achieved
in centrifuges.

The invention of the optical microscope allowed people to observe bacteria, and centrifuges enabled people to extract bacteria and later viruses, such as hepatitis
viruses.

The operating system for the separation, purification and extraction of samples with a centrifuge is called centrifugal separation operation, and its technology is centrifugal separation technology, referred to as centrifugal technology
.

Centrifuges are divided into industrial centrifuges and laboratory centrifuges according to the industry or scale used
.

The amount of processing materials in industrial centrifuges is large and the volume and weight of centrifuges are also large, but the degree of separation is poor, mainly used in
industrial production.

The processing capacity of the laboratory centrifuge is small, and the volume and weight of the centrifuge are also small, but the degree of separation is better, mainly used in the separation extraction and analysis research
in the laboratory.

In particular, the emergence of low-speed refrigerated large-capacity centrifuges and high-speed refrigerated centrifuges has made centrifuges a truly powerful conventional instrument.


The perfection of the centrifuge product range meets the various requirements of users and promotes the development
of biochemistry and other related fields.

In the centrifuge series, the design and manufacture of ultracentrifuges is difficult, and its wide application in modern biology such as molecular biology has promoted the development of ultracentrifuge design and manufacturing technology, making it a very complete experimental equipment
.

The emergence of centrifuges in modern science began with ultracentrifuges, and its design and manufacturing technology represents the high-tech level
of centrifuges.

First, the operating procedure: 1.
Plug in the power supply, standby indicator light on: turn on the power switch, speed regulation and timing system of the digital tube display flashing number for the machine working speed factory settings
.

2.
Set the working parameters of the machine, such as working temperature, running time, working speed, etc
.

With the run button on the control panel, the centrifuge starts to run
.

During the pre-set acceleration time, its speed rises to a pre-set value
.

During the pre-set operating time (excluding the deceleration time), the centrifuge begins to decelerate, and its speed is reduced to zero
during the pre-set deceleration time.

Press the stop button on the control panel and the digital tube displays the dedT, which displays a flashing speed value after a few seconds, when the machine is ready for the next job
.

Second, the precautions: 1.
In addition to the running speed and running time, do not arbitrarily change the working parameters of the machine, so as not to affect the performance of the
machine.

2.
The speed setting shall not exceed the high speed to ensure the safe operation of
the machine.

3.
If there is 0.
00 or other numbers in use, the machine is not running, it should be shut down and powered off, restart after 10 seconds, and then press the operation key after the set speed display, and the machine will run
as usual.

4.
The lid door
must not be opened during the operation of the machine or when the rotor is not stopped.

5.
Centrifuge the sample in equal amounts, do not make the rotor run
in unbalanced conditions.

6.
Centrifuge do not exceed 60 min
at a time.

7.
Centrifuge reliable grounding; The machine is not used, and the power plug should be unplugged
.
