Three Steps to Eliminate Centrifuge Safety Hidden Trouble

2018/5/14 10:08:38      click :
  As one of the indispensable devices in the pharmaceutical industry, centrifuges have been developing rapidly. Centrifuges are widely used in the medical field, and centrifuges are widely used in blood separation, virus research, DNA research, drug purification, and the like. Centrifugation is the use of the centrifugal force generated by high-speed rotation of the centrifuge rotor to accelerate the settling velocity of the particles in the liquid and separate the sedimentation coefficient and buoyancy density of the sample.
  Centrifuges have a cylinder that rotates at high speed around its own axis, called a drum, usually driven by an electric motor. After the suspension (or emulsion) is added to the drum, it is quickly driven to rotate at the same speed as the drum. The components are separated under centrifugal force and discharged separately. In general, the higher the drum speed, the better the separation effect.
  Centrifuge usage rules:
  1. When the centrifuge is in the pre-cooling state, the cover of the centrifuge must be closed. After the end of the centrifugation, the rotating head should be removed and placed on the experimental bench. The remaining water in the cavity should be wiped off and the cover of the centrifuge should be opened.
  2. When turning the head in the pre-cooling, the rotating head cover can be placed on the platform of the centrifuge, or placed on the experimental bench. It must not be tightened and floated on the rotating head, because once the head is turned on, the head cover will be turned on. Will fly out and cause an accident!
  3. After turning the cover, be sure to touch the rotating head and the cover with your fingers without gaps. If there is any gap, you should unscrew it and tighten it again until you can confirm that there is no gap before you start the centrifuge.
  IV. In the process of centrifuging, the operator must not leave the centrifuge room. If an abnormal situation occurs, the operator cannot turn off the power (POWER) and press STOP. Before the pre-cooling, it is necessary to fill in the records of the use of the centrifuge.
  V. Do not use shriveled centrifuge tubes. Do not use aged, deformed, cracked centrifuge tubes.
  VI. The last one after a routine safety inspection using a centrifuge on holidays and in the evening can leave.
  VII. In the process of using the instrument, it is necessary to contact us in time when there is a machine failure or a damaged part.
  Three steps to eliminate safety hazards in centrifuges:
  Centrifuges play an important role in many industries where we live. He is a high-speed machine, like in the chemical, inspection, pharmaceutical and other industries. There are security risks in many industries. These hidden dangers threaten our lives. Therefore, when we operate centrifuges, we must pay attention to some principles of use.
  1. When we pre-cool the centrifuge, we must ensure that the centrifuge lid is closed, when it is over, we should take out the inverted rotor on the test bench, and then dry the remaining water in the cavity, let the centrifuge The lid is open.
  2. When the pre-cooling can be placed on the centrifuge rotor platform, or on the test bench, can not be placed on the rotor without tightening, because once the wrong start, the rotor head will fly out Caused an accident.
  3. After tightening the rotor cap again, we must touch it with our fingers to see if there is any gap between the rotor and the cap. If there is a gap between the rotor and the cap, we must unscrew it and re-tighten it until we know that there is no gap. machine. During the inspection process, pay attention to the rotor body to see if there are cracks, because some manufacturers use materials that have not been reinforced, so in the case of high-speed operation, the rotor is easily torn, which is very dangerous, so we If cracks are found, contact the manufacturer in time.
  The three steps teach you how to prevent the safety hazards of the centrifuge. This also provides protection for your safety. I hope you can pay more attention to the above mentioned content.
  With the rapid development of centrifuges, market demand is gradually increasing, and product categories are becoming more and more abundant. Many users have made difficult choices. In the centrifuge, the motor is an indispensable accessory that reduces the operating noise, lowers the motor temperature, and lubricates the bearings. The same centrifuge can be equipped with a brush motor or a brushless motor, and the user can choose between the advantages and disadvantages of both, and it can also be a standard to be measured when selecting a product.
