5. Operating Instructions

5.1. Aspiration (Drawing Liquid)

1. Press the plunger button down to the first stop.
2. Immerse the tip into the liquid to the appropriate depth (typically 1-2 mm for small volumes).
3. Slowly release the plunger button to aspirate the liquid. Wait a moment for the liquid to fully enter the tip.
4. Remove the tip from the liquid, touching it against the edge of the container to remove any excess droplets.

5.2. Dispensing (Releasing Liquid)

1. Place the tip against the inner wall of the receiving vessel at a slight angle.
2. Press the plunger button down slowly and smoothly to the first stop to dispense the liquid.
3. Continue pressing the plunger button to the second stop (blow-out) to ensure complete expulsion of the liquid.
4. While holding the plunger button at the second stop, withdraw the tip from the vessel.
5. Release the plunger button.

5.3. Tip Ejection

After dispensing, press the tip ejector button to discard the used tip into an appropriate waste container.

6. Maintenance and Cleaning

Regular maintenance ensures the longevity and accuracy of your DLAB Micropette Plus pipette. This model is fully autoclavable, simplifying sterilization.

6.1. Daily Cleaning

• Wipe the exterior of the pipette with a soft cloth dampened with 70% ethanol or a mild detergent solution.
• Do not immerse the entire pipette in liquid unless performing autoclaving as per instructions.

6.2. Autoclaving

The DLAB Micropette Plus is fully autoclavable at 121°C (250°F) for 20 minutes at 1 bar (15 psi) pressure. Ensure the pipette is disassembled according to the manufacturer's guidelines (refer to specific disassembly instructions if provided with the product, or consult DLAB's official resources) before autoclaving. Allow the pipette to cool completely and dry thoroughly before reassembly and use.

6.3. Calibration

The pipette features easy calibration. Regular calibration checks are recommended, especially after extensive use, autoclaving, or if accuracy is suspected to be compromised. Refer to a certified calibration service or DLAB's official calibration procedures for detailed instructions. Calibration typically involves gravimetric testing using distilled water at a controlled temperature.
