Frequently Asked Questions – Electronic Macro I am left-handed. Can I use the macro Ovation pipette? Do I have to setup a pipetting function each time I use it? How often do I need to recharge the battery? How long does it take to recharge? How often do I need to change the battery? Can I operate the pipette plugged in? What does the “c” on the display mean? At what volume should I verify my macro Ovation pipette? Can I calibrate the Ovation pipette myself? I can’t reach the bottom of my taller flasks. What do I do? Will I need to calibrate my pipette when used with serological pipets? I am left-handed. Can I use the macro Ovation pipette?return to faq All Ovation pipettes have an adjustable hook that allows the user to find the most comfortable position for the pipette to fit comfortably in the palm of the hand. In addition, macro Ovation pipettes are available in “left-hand” models where the LCD screen is placed on the right side of the pipette for easier viewing by left-handed users. To order a left handed model, identify the catalog number of the desired model and add an “L” at the end of the number. Do I have to setup a pipetting function each time I use it?return to faq Macro Ovation pipettes always store the last setting(s) used for any liquid handling function. It is only necessary to setup a function if the required settings have changed. How often do I need to recharge the battery?return to faq An icon on the display indicates the battery charge. When the icon begins to flash, the battery is approaching a low battery level and you should consider plugging in the AC Power Supply to continue operations or recharging at your earliest convenience. Unlike other pipettes, the pipette can remain connected to the AC power supply whenever it is not in use. How long does the battery take to recharge?return to faq A fully drained battery takes 90 minutes. How often do I need to change the battery?return to faq The battery should only need to be changed every 2-3 years depending on use. Can I operate the pipette plugged in?return to faq Yes. What does the “c” on the display mean?return to faq A “c” will be displaced on the lower left area of the display only when the pipette has been set to a calibration factor of other than the factory setting of 1.000. A setting of other than 1.000 may be necessary to optimize performance when using a serological pipet (because of the additional length of the air column) or as a result of environmental conditions, pipetting techniques or viscosity and density of liquids being pipetted. At what volume should I verify my macro Ovation pipette?return to faq Unless the pipette is used only at one set volume, the pipette should be verified at the low, mid-range and high volume settings. Unlike other pipettes, accuracy and precision specifications for the Ovation apply to the entire operating range, not just to certain points of the pipette’s range. Can I calibrate the Ovation pipette myself?return to faq Yes. Software for in-lab calibration is internal to the pipette. Once you have determined the actual volume that the pipette is delivering, this value can be directly entered into the calibration software. That’s all it takes. A known calibration factor for any liquid can also be entered at any time. At what volume should I dispense when verifying calibration or changing calibration for a specific liquid?return to faq • For pipetting performance across the entire range, calibration verification should be based on the volume delivery at the pipette’s maximum volume. • For optimum performance with a specific liquid at a set volume, use that volume setting. If the specific liquid is dispensed at multiple volumes, then use the pipette’s maximum volume. I can’t reach the bottom of my taller sample tubes. What do I do?return to faq The macro Ovation pipette can be used with glass and plastic serological pipets when an extra length is needed to reach the bottom of tall vessels. On the 10mL model, simply insert the end of the pipet into the end of the nozzle. On the 5mL model, an adapter is required (Sero-Adapter, VistaLab Cat #9060-5012), which easily attaches to the pipette in place of its standard nozzle, and provides the capability of using serological pipets. Will I need to calibrate my pipette when used with serological pipetsreturn to faq For optimum performance, you may want to use the internal calibration software to adjust volume delivery in order to have the meniscus at the calibrated line of the pipet. What is the meniscus?return to faq The meniscus is the lowest part of the liquid when sighted at eye level.
