Insert the tip of the pipette into the liquid and then press the middle valve to draw liquid into the pipette to the desired volume. • A tube of lubricant jelly. Set the volume within the range specified for the pipette. These pipettes have a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a single volume (like a volumetric flask). Disposable capillary pistons are pre-assembled and racked just like regular pipette tips. Aspirate liquid into the tip and dispense two or three times before taking up the desired volume. Pipette failures typically occur due to degraded parts in the lower section of the pipette like the o-ring, piston, and tip holder compromising the pipette’s airtightness.

These soft, flexible plastic transfer pipettes save you time when mixing cross-contamination. • Send the pipette to a pipette calibration service. Graduated cylinders are great for the measurement of bulk volumes. Using your P200 micropipette, you want to obtain 150 μL of water. After the pipette is operated, there are a few more TIPS to remember: • Do not use a large-range pipette to transfer small volumes of liquid; • Use a pipette tip that matches the pipette;. With the pipette in the bath, the current response to the test pulse is determined by the pipette resistance (R P), which can be calculated using Ohm’s law: R P = V T / I P, where V T is the amplitude of the voltage test pulse and I P is the current through the pipette. Differences in technique - some more than others - can alter delivery volumes. The use of seven Stäubli Scara robots, three Acopostrack transport loops, state-of-the-art machine vision and laser scanning systems has resulted in one of the most modern and compact production solution in the history of Robotec. • When using solutions with physical characteristics which are considerably different from those of water [e.
