Adjustable pipettes are ideal manual pipettes for a variety of demanding applications in the laboratory. Features robust construction, pipetting volume adjustment, autoclaving, high accuracy, easy calibration technology and long-term reliable performance. Adjustable pipettes should be maintained according to frequency of use, but at least every 3 months, as follows:
1. For general maintenance, use neutral detergent to clean, or use 60% isopropyl alcohol, then repeatedly wash with distilled water, remove the detergent or isopropyl alcohol, dry it, and use a certain amount of lubricant on the piston after cleaning.
2. If there is serious contamination of liquid entering the sampler, the sampler can be disassembled and cleaned. For the specific disassembly steps, please refer to the sampler manual.
3. High pressure sterilization. The straw part of some samplers can be sterilized by high pressure, but it should be noted that the disinfection should not be overheated for a long time, and it should not be squeezed to avoid deformation.
4. The adjustable pipette should be properly erected on the stand when not in use, away from moisture and corrosive substances.
5. In order to prevent the liquid from entering the sampler sleeve during the pipetting operation, it must be noted that the button should be kept stable when pressing and releasing; the sampler should not be reversed, and the sampler should not be placed flat when there is liquid in the tip.
6. Before starting work every day, check whether there is dust or dirt on the outer surface of the pipette, and wipe it off carefully if there is.
