3ml Pipette with 0.5ml Graduations
Probably the best way of dispensing caustic liquids like pH up alkalis or pH down acids is with a pipette. This 3ml pipette can be re-used many, many times and is marked with 0.5ml graduations for accurate measuring.
How Disposable Pipettes Work
The 3ml pipette with 0.5ml graduations is a plastic tube with a small nozzle at one end and a bulbous end at the other.
The tube has markings in 0.5ml graduations for accurate measurement. When the nozzle end is placed in a liquid and bulbous end is squeezed and released, the pipette will suck the liquid into the tube and the markings show how much liquid has been drawn out. For most liquids it will take a few seconds for the bulbous end to completely stop drawing liquid up.
The nozzle end of the pipette can then be taken out of the liquid and the surface tension in the nozzle will retain the liquid inside the tube, preventing it from dripping out. The measured amount of liquid can then be added to a reservoir by simply squeezing the bulbous end again.
