a. After each experiment, the scale of the pipette gun should be adjusted to the maximum so that the spring can return to the prototype to extend the service life of the pipette gun. b. Pipettes with liquid suction should not be placed flat: the liquid in the head can easily contaminate the inside of the gun and may cause the spring of the gun to rust. c. When setting the range, please be careful to rotate until the required range number is clear in the display window, and the range set is within the range of the pipette. Be careful not to rotate the button out of the range, otherwise it will jam the mechanical device and damage the pipette.

2. Can the DLAB pipette tolerate ultraviolet disinfection?
After ultraviolet disinfection for several times, the color of the pipette will change, the material will become brittle and shorten the quality life of the pipette equipment. It is recommended that the ultraviolet disinfection should not exceed one hour each time, and the ultraviolet disinfection frequency is not too much. It is recommended that customers use high temperature and high pressure disinfection; The MicroPlus series does not need to be disassembled, and can withstand high-temperature and high-pressure sterilization. Piston components of TOP and Micro series can withstand high temperature and high pressure disinfection after disassembly, as shown in the figure below. The outer wall of the pipette gun is cleaned regularly. It can be cleaned with 95% alcohol or 60% isopropyl alcohol, wiped with distilled water and dried naturally.
3. After high temperature disinfection, how long should the manual pipette be cooled before it can be used?
After high temperature disinfection, it needs to be fully cooled, it is recommended that more than 3 hours, and recalibrate before use.
4. Does the DLAB pipette need to be recalibrated after high temperature disinfection?
Recalibration is required after high temperature disinfection.
5. When should the pipette be recalibrated?
It is recommended to calibrate 1-2 per year according to the frequency of use.
6. Pipette calibration reference and fine tuning method?
To correct by the method of calculating the weight of pure water taken from the weighing of the analytical balance in parts per hundred thousand or parts per million. 1ml distilled water weighs 1.000g at 20℃. The capacity can be increased by turning the nut clockwise with the calibration tool when the capacity is small. If the capacity is too large, use the calibration tool to turn the nut counterclockwise to reduce the capacity.

The type of centrifuge rotor is introduced
Fixed Angle rotor refers to a fixed Angle between the central shaft of the centrifugal tube and the rotating shaft, most of which is between 14 and 45 degrees. The larger the Angle, the better the separation effect. The advantages of this rotary head are low center of gravity, balanced operation, and can quickly collect sediment. However, when the particles settle, they will hit the centrifugal tube along the centrifugal force direction, and then slide along the tube wall to the bottom of the tube, forming precipitation. The wall effect is easy to cause strong convection in the tube, affecting the separation effect.
