  1. May 10, 2016 · High precision for defined volumes. Pipetting of small volumes from 0,1 up to 5000 microliters is commonly carried out by using micropipettes. The basic function of these precision instruments results from a piston-driven air displacement. When the piston inside the pipette is pressed down, the internal air is displaced.

  2. May 7, 2017 · Keep in mind that analytical balances are far more accurate than any pipette. Dispense volumes appropriate for your instrument, but at the same time use the largest volume possible for your experiment. For example, consider diluting samples to deliver the same quantity of reagent in a larger volume. Good practice vs. best practice.

  3. Use the following information to calculate metric volume conversions: 1 µL = 10 –6 L = 10 –3 mL. 1 nL = 10 –9 L = 10–6 mL. 1000 nL = 1 µL. 0.001 µL = 1 nL. Micropipettes. are among the essential laboratory instrument used to accurately distribute different volumes of liquids in the microliter range. In order to prevent cross ...

  4. Study with Quizlet and memorize flashcards containing terms like Why is it important to post-rinse when pipetting volumes less than 20 microliters? A. Smal volumes wil evaporate prior to transfer B. You cant accurately pipette less than 20 microliters C. You dont need to post-rinse small volumes D. Small volumes may not get expelled completely due to surface tension, T/F. Pipettors are most ...

  5. Before aspirating, it is important that you immerse the tip properly below the meniscus. For large volume pipettes (1-5 mL), the immersion depth should be at least 5-6 mm, while for smaller volume pipettes, the depth should be around 2-3 mm. If you immerse it too little, specifically the large volume pipettes, it can result in the aspiration of ...

  7. Sep 25, 2023 · Pipettes are laboratory instruments used to measure and transfer small volumes of liquid accurately. They are essential tools for a wide range of scientific and medical applications, including chemistry, biology, and medicine. Pipettes come in various designs, each with its own strengths and limitations. 1.
