Instruction Manual

Manual

Pipette Controller

Product Description: The Manual Pipette Controller is a simple

hand operated instrument for ﬁlling and dispensing pipettes. The

Manual Pipette Controller accommodates graduated or volumetric

pipettes (made of glass or plastic) and can be used with volumes

ranging from 1 to 50mL.

Caution!Take care to avoid aspirating liquid into

the Manual Pipette Controller which can impair performance.

If liquid is aspirated into the unit, clean the pipette adapter

and nose cone per cleaning instructions (see below) under

maintenance. If necessary replace the ﬁlter.

How to Use

1. Attaching the Pipette: While holding the top of the Manual

Pipette Controller with one hand, carefully push the pipette into

the silicone adapter inside the nozzle, twisting it slightly. Excessive force can cause the

pipette to break. Use extra caution when inserting thin pipettes.

2. Aspirating: Immerse the pipette tip into the liquid. Squeeze the rubber bulb until sufﬁciently

deﬂated. Push the toggle upward to aspirate. The speed of aspiration is dependent on

the amount the toggle is pushed upward from center position. When released, the toggle

comes back to center position and aspirated liquid is held in place.

3. Dispensing: Place the pipette tip at an angle against the inside of the receiving vessel.

Slowly push downward on the toggle; dispensing speed is dependent on the amount the

toggle is pulled downward from center position.

4. Blow Out: Push the blow-out bulb to expel the liquid remaining in the pipette. This may

need to be repeated several times to completely expel all liquid.

Maintenance

The Manual Pipette Controller is normally maintenance-free. When necessary, the housing can

be wiped occasionally using a damp cloth.

Caution! When cleaning and exchanging the ﬁlter, wear protective gloves

and safety goggles to avoid the risk of splashes and contamination.

Cleaning the Pipette Adapter and Replacing the Filter

If liquid has entered the nose cone or if the aspirating efﬁciency has decreased, observe the

following instructions:

1. Hold the pipette over a container and remove the pipette.

2. Gently unscrew the nose cone.

3. Remove the ﬁlter.

4. Remove the pipette adapter from the nose cone by pushing it upwards.

5. Rinse the pipette adapter with demineralized water and allow to dry at room temperature.

6. To insert a ﬁlter, face the side imprinted with the Whatman®name and ﬁlter size toward the

pipette adapter and push in. The side of the ﬁlter with a smooth protrusion and no imprinting

should now be visible.

7. Reassemble the Manual Pipette Controller by reversing the steps above.

8. Test Manual Pipette Controller for leaks, see “Checking for Leaks”.
