Page 10: Setting The Volume
• After pipetting acids or other corrosive liquids that emit vapors, remove the tip-cone and rinse the piston, O-ring and seal with distilled water. • Do not pipette liquids having temperatures above 70°C. (Not recommendable) • Make sure that liquids never enter the tip-cone. To prevent this: Avoid laying the pipette horizontally when tip is filled with sample. -
Page 11: Loading Tips
Setting the volume beyond the allowable volume range is not permitted. Using excessive force to turn the volume adjustment knob outside the permitted range will jam the mechanism, damage the pipette and void the warranty. 5.3 LOADING TIPS Using correct pipette tip according to the pipette volume range is recommended. -
Page 12: Reverse Pipetting
5.6 REVERSE PIPETTING The reverse pipetting technique is suitable for dispensing liquids that have high viscosity or a tendency to foam easily. This technique is also recommended for dispensing very small volumes. Press the operating knob until the second stop. Dip the tip under the surface of the liquid in the reservoir and slowly release the operating knob. -
Page 13: Devise Requirements And Test Conditions
6.1 DEVISE REQUIREMENTS AND TEST CONDITIONS An analytical balance must be used. The balance selection depends upon selected model of the pipette and sensitivity of balance reading. Test liquid: Water, distilled or de-ionized, grade 3 water conforming ISO3696 Calibration should be carried out in a draft-free room at a constant (±0.5°C) temperature of water, pipette and air between 15°C to 30°C. -
Page 14: Conversion Of Weight Readings To Volume
• Calculate the inaccuracy and imprecision for all three volumes as per EN ISO 8655-6 standards on the basis of the following calculation 6.3.1 CONVERSION OF WEIGHT READINGS TO VOLUME Mean Volume Mean Weight Balance Reading number of reading Conversion factor [example Z=1.0040 µl/mg at 25°c and 1013 hPa] 6.3.2 CALCULATION FOR IN-ACCURACY (SYSTEMATIC ERROR) Mean Value... -
