Operating Exclusions

The HandyStep

is a repetitive pipette for quick and simple repetitive

dispensing of liquids. Volumes from 2 µl to 5 ml can be dispensed with

the highest precision and accuracy through combinations of the PD-Tip

size used and adjustment of the stroke setting on the stroke-setting

wheel.

This instrument is designed for dispensing samples, observing the follow-

ing limits:

– use between +15 °C and +40 °C (59 °F and 104 °F)

(of instrument and reagents – other temperatures on request)

– vapor pressure up to 500 mbar

– viscosity: 20 mPa s with 50 ml PD-Tips

260 mPa s with 5 ml PD-Tips

977 mPa s with 1 ml PD-Tips

Limitations of Use

Function and Limitations of Use

Instrument and tips are not autoclavable (sterile PD-Tips, see page 37).

PD-Tips are disposables. For disinfection of the instrument you may use

commercially available disinfecting solutions as long as they do not attack

PC/PBT and PC.

Note:

During proper operation, the dispensed sample only comes in contact

with the tip and not with the HandyStep

The user has to ensure the compatibility of the instrument with the inten-

ded application. In case of third-party dispenser tips, the user must check

their compatibility and perform a function and volume test before use.

The instrument should not be used for dispensing liquids that attack

polypropylene (e.g., PD-Tip cylinder), polyethylene (PD-Tip piston), LCP

(PD-Tip piston 0.1 ml), or PC/PBT and polycarbonate.
