Which repeating pipette tips work with my HandyStep® repeating pipette?
The HandyStep® repeating pipette is designed to work with all standardized repeating pipette tips. These include BRAND PD-Tip™ syringe tips, Fisherbrand tips, VWRbrand tips, Ritips, Labnet Combi-syringes, Rainin Encode tips, and Eppendorf Combitips. They will even work with the proprietary-design Eppendorf Combitips Advanced. Other proprietary designs, like those from Wheaton, Oxford and ThermoLabsystems will not work with the HandyStep®. The HandyStep® electronic will automatically recognize the size of BRAND PD-Tips™ and Rainin Encode tips.
How do I calibrate my HandyStep®?
A Standard Operating Procedure (SOP) for gravimetric testing of the HandyStep® is available on this website: click here. Because the instrument and the syringe tips are equal partners in the accuracy of the instrument, if you find that your instrument is not performing to specification with third-party tips, we recommend that you try BRAND PD-Tip™ syringe tips to confirm the source of the error. PD-Tip™ syringe tips are supplied with a Certificate of Performance in every box. It should be noted that bubbles in the tip are also a common source of error. Adjustment of the instrument by the end-user is not possible. If you find that your instrument requires adjustment, we recommend that you contact BrandTech® for authorized service.
How does my HandyStep® S work?
The HandyStep® S has a series of finely machined notches into a corrosion resistant rack that moves the piston of the PD-Tip™ the indicated number of millimeters for each movement of the actuation lever, depending on the setting. These correspond to 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9% and 10% of the nominal capacity of the tip used.
How do I fix my HandyStep®?
The HandyStep® has a number of small parts inside. We do not recommend opening the instrument, as it is unlikely that you will be able to reassemble it correctly, and doing so will void your warranty. We recommend that you contact BrandTech® for authorized service.
Why does the frame around my battery charge icon on my HandyStep® electronic blink?
This indicates that the instrument has not undergone a full battery charge/discharge cycle with the battery inside the instrument, and as such the battery charge indicator is not as accurate as it would be otherwise.
How long does it take to charge the battery in my HandyStep® electronic?
2.5 hours with the battery removed from the instrument, 3.5 hours with the battery inside the instrument.
How long does the battery charge last?
Approximately 2.5 hours of continuous pipetting with a 12.5mL tip, for liquids with a viscosity and density similar to water. Because of the amount of friction, and liquid moved varies with the size of the tip, larger tips have shorter charge life, while, conversely, smaller tips provide less of a drain on the battery.
The display of my HandyStep® electronic shows "ERR 00x." What should I do?
A list of error codes, and their meaning is below:
- ERR 001: Tip recognition error, or locking lever not engaged/open.
- ERR 002: This error indicates a motor strain or blockage. If a tip or adapter is stuck, do not attempt to remove it as this could cause further damage to the instrument.
- ERR 003 or higher: These error messages indicate an electronic failure.
For all error messages - press enter to confirm, and follow the MENU instructions. For more detailed instructions, see the operating manual. If it is not possible to clear the error after following the instructions, Contact BrandTech® for repair.
All through the catalog, it mentions that the "Standard Operating Procedure" for instrument calibration is available. How do I get one?
