When your lab function calls so that you can evaluate or transfer modest volumes of liquid, precision and precision are vital.

They're relevant in very simple laboratories for handling liquid specimens and reagents that aren't unstable or do not need significant contamination risk.

Serological pipettes, often known as blowout pipettes, are made for measuring and transferring larger sized volumes of liquid.

Pink pipette filler for Risk-free pipetting of caustics, it doesn't comprise carbon black and will likely not smudge
