Safety Instructions Please read the following carefully! This instrument may sometimes be used with hazardous materials, opera- tions, and equipment. It is beyond the scope of this manual to address all of the potential safety risks associated with its use in such applications. It is the responsibility of the user of this pipette to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Limitations of Use Purpose The pipette is an air-displacement system for pipetting aqueous solutions with medium density and low to medium viscosity. Limitations of Use The instrument is intended for the pipetting of liquids within the following limitations: – use temperature from +15 °C to +40 °C (59 °F to 104 °F). Consult the manufacturer for use in temperatures outside of this range.
Pipette shaft Tip cone (Fig. shows Transferpette ® adjustable volume) Note: Optimum analysis results can only be obtained with quality tips. We recommend pipette tips from BRAND. For further information, refer to the accuracy table on pages 37 and 38.
Pipetting 5 ml and 10 ml instruments should only be used with the PE filter installed (see page 40). Pipette tips are disposables items! Fitting the tip Use the correct tip according to the volume range or the color code. Ensure that the tip is securely seated.

Pipetting Ejecting the tip Hold the pipette shaft over a suitable disposal container and press the tip ejection key to the stop. Note: ISO 8655 prescribes rinsing the pipette tip once with the sample liquid prior to the actual pipetting process. Important! Don't lay the instrument horizontal when the tip is filled.
Checking the Volume Depending on use, we recommend inspection of the instrument every 3 to 12 months. The cycle can, however, be adjusted to individual requirements. The gravimetric testing of the pipette volume is performed according to the following steps and is in accordance with DIN EN ISO 8655, Part 6. Set nominal volume Set volume to the maximum volume indicated on the instrument (see page 32 for procedure).

*) = Calculation of accuracy (A%) and variation coefficient (CV%): A% and CV% are calculated according to the formulas for statistical control. Note: Testing instructions (SOPs) and a demo version of the EASYCAL 4.0 calibration software are available for download at www.brand.de.
Adjustment – Easy Calibration The instrument is permanently adjusted for aqueous solutions. If the pipette operation is clearly inaccurate, or if the instrument must be adjusted for solutions of different densities and viscosities or specially- shaped pipette tips, adjustments can be made using the Easy Calibration Technique.
