How to set micropipette

NOTES: • Never point a pipette up. This may cause liquid to run down into the pipette destroying it. • When withdrawing liquids with the pipette, always release the plunger slowly. This prevents liquid from rushing into the end of the pipette and clogging it up. This is especially important with large volume pipettes (200-1000 !l). • Be sure you use the proper size tip for each pipette. • Always use a new tip for each different liquid. • Use the correct pipette for the volume that is to be dispensed. Never use the 200-1000 !l pipette to dispense volumes below 200 !l. going below or above the range of the micropipette may damage the instrument. Set the desired volume by turning the centrally located rings clockwise to increase volume or counterclockwise to decrease volume. P10: Maximum volume 10 !l. Accurate between 1 !l and 10 !l. Numbers on the micropipette (typically black-black-red) are read as XX.X !l. The change in color indicates the position of the decimal point. P20: Maximum volume 20 !l. Accurate between 2 !l and 20 !l. Numbers on the micropipette (typically black-black-red) are read as XX.X !l. The change in color indicates the position of the decimal point. P200: Maximum volume 200 !l. Accurate between 20 !l and 200 !l. Numbers on the micropipette (one color) are read as XXX !l. P1000: Maximum volume 1000 !l (= 1 ml). Accurate between 200 !l and 1000 !l. Numbers on the micropipette (typically red-black-black) are read ml. Note that this micropipette reads milliliters while the other two read microliters. #LabSafety #PipetteTips #Micropipettes #LiquidHandling #LabTechniques #ScientificEquipment #PipetteUsage #LabSkills #VolumeMeasurement #LabProcedures #PipetteAccuracy #LabInstruments #LabProtocol #ScientificResearch #LabTools #LiquidDispensing #LabTraining #PipetteInstructions #LabBestPractices #PipetteMaintenance #LaboratoryGuidelines
