OPERATION

Place a tip on the shaft of the pipette. See Section 6 for the appropriate tip. Press the tip on firmly using a slight twisting motion to ensure a positive, airtight seal. Note: Never handle a liquid with a BioPette™ which has not been fitted with a tip. Aspiration Press the pushbutton to the first positive stop, Fig. 2A. Holding the pipette vertically, immerse the tip into the sample liquid. The depth to which the tip is immersed in the sample liquid depends on the model. Release the pushbutton slowly and smoothly to aspirate the sample, Fig. 2B. Wait one second and then withdraw the tip from the liquid. Wipe any droplets away from the outside of the tip using a medical wipe. Avoid touching the orifice of the tip. Dispensing •Place the end of the tip against the inside wall of the vessel at an angle of 10 to 40 degrees. •Press the pushbutton smoothly to the first stop, Fig. 2C. Wait one second. •Press the pushbutton to the second stop to expel any remaining liquid, Fig. 2D. •Keeping the pushbutton pressed to the end, remove the pipette by drawing the tip along the inside surface of the vessel. •Release the pushbutton, Fig. 2E. •Eject the tip by pressing the tip ejector button, Fig. 2F. It is only necessary to change the tip if a different liquid is being sampled or if the volumeter setting is changed. Filters A replaceable filter installed in a seat in the bottom part of the shaft is used in 5000 µl and 10000 µl pipettes (Fig. 3L). The filter prevents the aspirated liquid from entering into the shaft and thus from polluting the inside of the shaft and the piston. Using the filter is especially important when aspirating and dispensing large volumes of liquid. If the filter becomes wet during liquid aspiration it should be replaced with a new one.

PRE-RINSING

When pipetting liquids which have a viscosity and density different than water, for example organic solvents, a film of liquid is formed on the inside wall of the pipette tip. This film can create an error. Since the film remains relatively constant in successive pipetting operations with the same tip, this error can be avoided by forming the film before transferring the first sample. This is done by aspirating a sample and dispensing it back into the same vessel. Since the film is already formed, all of the following samples will have better accuracy and repeatability. This pre-rinsing operation should be repeated when the volume to be aspirated is changed or when a new tip is used.
