The multichannel Ovation BioNatural Pipette is an adjustable volume, air displacement, fully electronic motor-drivenpipette intended to aspirate and dispense precise fluid volumes. This can become even more laborious and time consuming of you consider a UKAS calibration! Per Channel Pipette Calibration for Multichannel Pipettes: Many scientists are not aware of the industry standard for how multichannel pipettes are calibrated. Deck calibration best practices Tip selection Use the thermometer to measure the temperature of the distilled water. Do ten pipettings with the lower calibration volume Do ten pipettings with the nominal volume. Be sure that the pipette is either vertical or within 20 ° of vertical. The micropipette kit also includes a sleek carousel stand and boxes of compatible tips for each pipette so that one does not have to go looking for the right tips. Unmatched expertise in pipette calibration and repair. A 2.2 point calibration on a 12-channel pipette requires 48 pipetting cycles and weighing's. Do not set volumes outside the pipette´s specified volume range. ID-tag You can mark the pipette application, your initials, the calibration date, etc. Pipette calibration table of Z factors for distilled water at 1 atm pressure Source: Wisconsin State Laboratory of Hygiene Steps Involved in Pipette Calibration • Take distilled water in a beaker and record its temperature. The multichannel Transferpette ® S pipette has a V-ring design that also fits most major brands. To decrease the delivery volume, turn it clockwise. Multichannel pipettes are available as 8- or 12-channel versions to work with 96-well microplates and as a 16-channel version to work with Leave your pipettes, pipette tips, distilled/deionized water (grade 3), and measuring balance in the test room for 2 hours or more before calibration. The accuracy of lab results can be directly affected by pipette problems. Calculation: (1) Convert the weight unit of measured value into the volume unit of measured value using the following formula: Volume ( ml or ul ) = Weight ( mg or ug ) x Z Z value : conversion factor, which is conversion of density ( see table 1 ) To do reverse pipetting, enter the program from the main menu. Calibration of the balance may be done by an external service agent or by yourself. The balance uncertainty contributes quite (if not most) significantly to the calibration of a pipette at lower volumes (typically below 100 µl). If you calibrate the balance yourself, use a set of mass pieces ranging from 1 mg to 100 g.
