Adjustable pipette is an indispensable tool in experimental operation. For top experts, it is important that the experiment has the smallest error and good reproducibility, so you must pay attention to the correct use of the pipette to avoid small losses.[ Pipette Tips,Tips Pipette,Pipette Tip 300,Filter Tips 1000,Pipette-Tip-Rack ]
Let’s take a look at what should be paid attention to when using adjustable pipettes:[ Pipette Tips,Tips Pipette,Pipette Tip 300,Filter Tips 1000,Pipette-Tip-Rack ]
1. Mounting the tip: push down the pipette sleeve handle forcefully, and rotate it slightly when needed.
Wrong operation: hit the tip hard. This method will cause damage to the tip and even wear of the pipette handle, which will affect its tightness.
2. Please select the correct pipette before the range setting operation. The pipette can be operated in the range of 10-100%, but the operation at 10% of the range requires high pipetting skills, so it is recommended to be 35-100 Operate within% of range. Range adjustment: When adjusting from a small range to a large range, rotate continuously in the direction of the required range, and then return to the required range when the rotation reaches 1/3 of the required range. When adjusting from a large range to a small range, it rotates directly and continuously to the required range.
3. Rinse the viscous liquid by pre-wetting the tip to achieve precise pipetting. First aspirate the sample liquid and pump it out. The inner wall of the tip will absorb a layer of liquid to make the surface adsorption saturated, and then suck the sample liquid. The final volume of the liquid will be very accurate. Repeat aspiration and drainage for the same sample two to three times, and rinse to provide the same contact surface for each subsequent aspiration to ensure the consistency of operation.
