3. Product Components

The Walfront 25ml Pipette Pump consists of several key parts designed for intuitive operation:

• Main Body: The red cylindrical housing of the pump.
• Thumb Wheel: A white, serrated wheel located at the top, used for precise aspiration and dispensing of liquids.
• Side Lever (Drainage Button): A white lever on the side, used for rapid dispensing of the entire pipette contents.
• Cone Nozzle: The white tip at the bottom where the pipette is inserted.
• Internal Piston/Rack: The mechanism inside that moves in response to the thumb wheel, creating suction or pressure.

4. Setup Instructions

Follow these steps to prepare your pipette pump for use:

1. Unpack: Carefully remove the pipette pump from its packaging. Inspect for any visible damage.
2. Select Pipette: Choose a disposable plastic or glass pipette compatible with the 25ml capacity of the pump.
3. Insert Pipette: Gently insert the wide end of the pipette into the cone nozzle of the pump. Apply slight pressure and twist gently to ensure a secure, airtight seal. Avoid forcing the pipette, as this may damage the nozzle or the pipette.

5. Operating Instructions

The Walfront Pipette Pump offers precise and rapid liquid handling:

5.1. Drawing Liquid (Aspiration)

1. Immerse the tip of the pipette into the liquid to be aspirated.
2. Rotate the thumb wheel upwards (towards the top of the pump). This action will draw the liquid into the pipette with precision. Continue rotating until the desired volume is reached.

5.2. Dispensing Liquid (Controlled)

1. Position the pipette tip over the receiving vessel.
2. Rotate the thumb wheel downwards (towards the pipette tip). This will dispense the liquid slowly and precisely.

5.3. Rapid Dispensing

1. To quickly dispense the entire contents of the pipette, press the side lever (drainage button). This will release the vacuum and allow the liquid to flow out rapidly.

6. Maintenance and Care

Proper maintenance ensures the longevity and accuracy of your pipette pump.

• Cleaning: After each use, especially when handling corrosive or biological liquids, remove the pipette and wipe the exterior of the pump with a damp cloth or a mild disinfectant solution. For internal cleaning, if necessary, consult with your lab's safety officer regarding appropriate cleaning agents for the materials of construction.
• Storage: Store the pipette pump in a clean, dry, and dust-free environment, away from direct sunlight and extreme temperatures.
• Inspection: Periodically inspect the cone nozzle for any signs of wear or damage that might compromise the airtight seal.
• Avoid Solvents: Do not immerse the entire pump in solvents or water unless specifically designed for such cleaning, as this may damage internal components.
