Error limits in relation to the set dispensing volume depending on the PD-
Tip size, at equal temperature (20 ºC) of instrument, tip, ambient environ-
ment and distilled water, and with uniform, jolt-free handling. The test is
carried out in accordance with DIN EN ISO 8655-5. The nominal volume is
the maximum volume printed on the PD-Tip.
10.2 Dispenser tips from other manufacturers
We recommend using BRAND PD-Tips II; however, the HandyStep® S can
also be used with compatible dispenser tips from other manufacturers.
When using compatible dispenser tips, the user must verify their suitabil-
ity and carry out a function/volume test!
