The pipette design enables the user to perform the recalibration process according to the rules presented in section 5. If the knob is accidentally turned too far, ie is set lower than the required value, the process must be repeated. The approach to the set volume must always be made in the order of decreasing value. 2 - SETTING THE VOLUME Volume is set using the pipetting pushbutton (Fig.
BPM/08/2004 v06 31/07/2004 01:06 PM Page 10 MULTICHANNEL 4 - RECOMMENDATIONS To achieve maximum safety, precision and reliability, the following principles should be observed: • do not draw liquids without tips fitted on the pipette cones, • do not lay down the pipette with tips filled, • do not draw volumes of liquid exceeding the pipette’s range, • check if the tips are fitted properly, • during operation, the pipette must be held vertically, tips should be immersed in liquid to the depth of 2 to 4 m
BPM/08/2004 v06 31/07/2004 01:06 PM Page 12 MULTICHANNEL • Perform three aspiration series (each series should include the aspirations from all channels), weigh each time and calculate the average value of the aspirations. • Calculate average aspirated volume in µl multiplying the average aspiration amount [mg] by the distilled water density coefficient [µl/mg], which depends on temperature and pressure according to the following table: Temperature [°C] Pressure [kPa] 95 101.3 105 20 1.0028 1.
