Setup and Initial Use

1. Unpacking: Carefully remove the micropipette from its packaging. Inspect for any visible damage.
2. Review Certificate: Locate and review the individual test certificate provided with your pipette. This document confirms its calibration and adherence to ISO8655 standards.
3. Tip Attachment: Select a suitable pipette tip for the 0.1-2.5µl volume range. Firmly press the pipette shaft into the tip opening with a slight twisting motion to ensure a secure, airtight seal. Do not overtighten.
4. Initial Volume Check: Before first use, set the desired volume and perform a few aspiration/dispensing cycles with distilled water to prime the pipette and ensure proper function.

Operating Instructions

1. Setting the Volume:

• Rotate the volume adjustment knob (located at the top of the pipette) to set the desired volume.
• Read the volume clearly on the digital display. Ensure the volume is within the pipette's specified range (0.1-2.5µl).
• Once the desired volume is set, engage the volume lock function (if available on your model) to prevent accidental changes during pipetting.

2. Aspiration (Drawing Liquid):

1. Press the operating button down to the first stop (the point of resistance).
2. Immerse the pipette tip into the liquid to be aspirated, ensuring it is just below the surface.
3. Slowly release the operating button to allow the liquid to be drawn into the tip. Wait a moment for the liquid to fully enter.
4. Remove the tip from the liquid, touching it against the edge of the container to remove any excess droplets.

3. Dispensing (Releasing Liquid):

1. Place the pipette tip against the inner wall of the receiving vessel at a slight angle.
2. Press the operating button down to the first stop to dispense the main volume of liquid.
3. Continue pressing the operating button down to the second stop (blow-out) to expel any remaining liquid from the tip.
4. While holding the button at the second stop, withdraw the pipette from the vessel.

4. Tip Ejection:

• After dispensing, point the pipette into a waste container.
• Press the tip ejector button (if present) to release the used tip.
• Dispose of the tip according to laboratory safety protocols.

Maintenance

Cleaning:

• The DLAB Hipette is designed with fully autoclavable materials. For sterilization, the entire pipette can be autoclaved at 121°C (250°F) for 20 minutes.
• After autoclaving, allow the pipette to cool completely before use.
• For routine cleaning, wipe the exterior of the pipette with a soft cloth dampened with mild detergent or ethanol. Avoid harsh solvents.

Calibration:

• Regular calibration checks are recommended to ensure continued accuracy, especially after extensive use or autoclaving.
• Refer to ISO8655 guidelines or consult a qualified calibration service for detailed calibration procedures.

Storage:

• Store the pipette vertically in a pipette stand when not in use to prevent contamination and damage to the tip cone.
• Store in a clean, dry environment, away from direct sunlight and extreme temperatures.
