Air-displacement pipettes operate perfectly with aqueous liquids, but if you're dealing with problematic liquids, you'll need a positive-displacement design. many of the biggest resources of pipetting faults are just due to not picking the right pipette for the liquid handling software concerned.
approach: Elbow flexion or abduction. Arm toughness diminishes as elbow posture is deviated from a 90° situation.
although pipettes provide precision and versatility, they even have limits, including the prospective for mechanical failure or user mistake. right instruction and routine maintenance are essential for trustworthy outcomes.
