Pipette operation 1.Sealing and ejecting tips Before fitting a tip, make sure that the pipette tip cone is clean. 2.Removing the tip ejector Please removing the tip ejector collar by following instructionPush the tip ejector down.Push the opening tool pin between the ejector bar and ejector collar to release the locking mechanism.Pull the ejector collar off. 3.Recommendations 1 After entering the tip at the lowermost end of the pipette handle, if operating inside the tip box, shake the pipette left or right while gently pressing down or slightly rotate the pipette (only the single pipette can be rotated) ) 1-2 seconds; if using a bulk tip, gently press the tip for 1-2 seconds while gently pressing the tip in the direction of the pipette. If this operation does not achieve the desired seal, it is necessary to check the tip and pipette. 2 The pipette controls the depth and angle of the aspiration: (1) Depth requirements for pipette tip immersion: The depth of the aspiration should be such that the desired pipette volume is achieved; The pipette keeps the outer wall of the tip as little as possible in contact with the liquid. (2) Pipette pipetting angle: The pipette must be kept in the vertical state during pipetting. 3 About pipette dwell time: Pipettes for large-scale pipetting (ml class) and viscosity is significantly higher than the pipetting of water samples, after releasing the thumb during pipetting, the tip must be allowed to stay in the liquid for 3-5 seconds before it can be removed. 4 About pipette storage: After the pipette has been used, the pipette must be adjusted to the maximum range and then hung up (can be hung on a dedicated stand or attached to the metal crossbar of the lab bench). 5.Packing 1x pipette 2x Tips 1x Simple barcket 1x Multi-tool 1x Instruction manual
