Basic selection principle of medical centrifuge

2019/3/22 11:38:51      click :
  In recent years, the market for medical centrifuges has been growing, and the future development potential is quite strong. It is a very good medical device industry. Medical centrifuges are ideal high-speed separation devices in the fields of biology, medicine, pharmacy, and epidemic prevention.
  Features of medical centrifuges:
  1. Microcomputer control, DC brushless motor drive, stable operation, low noise, strong sense of experience
  2, all steel shell, simple appearance, beautiful curve, using special shock absorption system, with automatic balance function
  3, touch panel, to achieve reading and setting between rpm / rcf, easy to operate
  4, with door cover protection, speeding and other protection functions, automatic fault alarm function, safe and reliable
  5, air-cooled centrifuge, effectively reduce the temperature rise during centrifugation
  6, a variety of capacity rotor options, cost-effective
  The basic selection principle of medical centrifuges:
  1. Separation purpose: Medical centrifuge is mainly used for blood separation.
  2, the rotation speed requirements: The maximum speed of the medical centrifuge when separating blood is generally 4000 rpm, the maximum rotation speed for DNA identification sample separation is generally above 10,000 rpm.
  3, capacity requirements: refers to the capacity of the centrifuge tube and the maximum number of centrifuge tubes can be placed at one time. The centrifuge tube commonly used in medical centrifuges has a vacuum blood collection tube, and the vacuum blood collection tube has two specifications of 5 mL and 7 mL. The outer dimensions of the 5mL vacuum blood collection tube (with cap): Φ12.5×81.5mm, the outer dimensions of the 7mL vacuum blood collection tube (with cap): Φ12.5×103mm, Φ12.5×106mm.
  4. Temperature control requirements: It means that it is not necessary to freeze when separating samples.
  Medical centrifuges are mainly used for routine blood tests in hospitals, and biochemical tests in hospitals. Blood tests are generally porous. There are 24 holes, 32 holes, 48 ??holes, 72 holes, 96 holes, and 120 holes. The holes are divided into long tubes and short tubes, the long tube is 5 ml, and the short tube is 3 ml. It is usually separated by a centrifuge at 3,500 rpm for 3-5 minutes. The size of the tubes for biochemical tests and routine blood tests is similar, except that the separation time is somewhat different, usually 3500 rpm for 5-10 minutes. Another is to use the virus test, this is generally used 1.5 / 2.0ml, 12000 rev / min go up, greatly improving the efficiency of the hospital.
