Pipette usage classic

1 When setting the pipetting volume

from large volume to small volume, it is the normal adjustment method, and the scale can be rotated counterclockwise

when adjusting from small volume to large volume, you can first adjust clockwise to the scale that exceeds the set volume, and then callback to the set volume, so as to ensure the best accuracy

2. Assemble the pipette suction head

single channel pipette, insert the pipette end vertically into the suction head, rotate slightly left and right, and tighten it

it is not advisable to use the pipette to repeatedly hit the suction head to tighten it. Such operation will cause the pipette parts to become loose due to strong impact, and serious conditions will lead to the knob for adjusting the scale. The growth of China's plastic machinery industry has been welcomed. Therefore, the operation method of this experiment is also applicable to the digital display wood-based panel universal experimental machine, which is stuck in the golden age of Kemen's growth and rapid growth

multi channel pipette, align the first channel of the pipette with the first suction head, insert it obliquely, shake it back and forth slightly, and tighten it. After the suction head is inserted, it can slightly exceed the O-ring

curing:

1. If the liquid enters the piston chamber accidentally, the pollutants should be removed in time

2. After the use of the pipette, adjust the range of the pipette to the maximum value, and place the pipette vertically on the pipette frame

3. According to the frequency of use, all pipettes should be cleaned regularly with soapy water or disinfected with 60% isopropanol, and then cleaned with double distilled water and dried

4. Avoiding environmental protection is the innovation direction of polyurethane materials. The temperature is higher to prevent deformation and liquid leakage or inaccuracy

5. Find professionals to deal with problems in time

precautions

1. Do not place the pipette horizontally or upside down when there is liquid at the suction nozzle of the pipette, so as to prevent the liquid from flowing into the piston chamber and corroding the piston of the pipette

2. Correctly use the pipette to suck and discharge liquid, so as to achieve the current high accuracy. Pay special attention to the drainage operation

3. Method of checking whether there is liquid leakage at ordinary times: stop in the liquid for seconds after aspirating to observe whether the liquid level in the suction head drops; If the liquid level drops, first check whether there is a problem with the suction head. If there is a problem, replace the suction head. If the liquid level still drops after replacing the suction head, it indicates that there is a problem with the piston assembly, and it should be repaired by professional maintenance personnel

4. For pipettes that need high-temperature disinfection, check whether the pipettes used are suitable for high-temperature disinfection before treatment
