An antidiffusion tip (6.1543.200) is available as an accessory. The antidif-
fusion tip is used whenever the titration tip is immersed into the sample.
The antidiffusion valve prevents the sample from diffusing into the tip.
If accurate dosing is important, a dosing tip (6.1543.060) can be ordered
as an alternative to the antidiffusion tip.
