1. Introduction
The LLG-Pipette Controller easy is an electrical pipetting aid designed for cordless work
with glass or plastic pipettes in 0.1 - 100 ml range. An ergonomically shaped and carefully
modeled lightweight handle, together with smooth push buttons and a conveniently located
slide switch ensure effortless pipetting even during extensive use. It has a high performance
micro pump with a powerful but quite engine with 3 speed modes. It is equipped
with a replaceable membrane lter, which protects the mechanism of the device from
contamination by vapors of solutions being drawn into the pipette. It has an autoclaveable
nosepiece and a continuous working limit of 8 hours.

4. Charging
Note: It is recommended to charge batteries every 3 months if the controller is not in use.
Even during the charging process, use of the pipette controller is possible.
Charging on Desktop stand: The pipette controller can also be charged conveniently when
it is placed on the desktop stand.
The LLG-Pipette Controller easy has a low battery LED indicator. If the LED lamp lights up,
it means that the batteries are discharged and they should be charged. The original charger
supplied along has protection against overcharging, short circuit & over tempered. The mains
voltage must conform to the specication of charger. Use of different chargers may damage
the batteries.
• Plug the charger into the Pipette Controller.
• Plug the charger into a suitable wall socket. The red indication on charger will light up
indicating that the charging process has started.
• Allow unit to charge for 3 - 4 hours (as this is a quick charger) for getting fully charged.
• Once batteries are fully charged, the charger automatically stops and the red indicator will
turn to green.
• This device has two (2) of 1000 mAH NiMH type rechargeable batteries.

5. Pipetting
First check the pipette to be used to ensure it is not damaged and has no dents or sharp
edges in the upper part. Check whether the upper gripping part is dry. Carefully hold the
pipette and insert it securely into the silicon holder inside the nose cone. Once the pipette
has been securely attached, always hold the instrument in a vertical position, tip down.
Speed Control: Set the pump speed using H / L / G Switch.
H : High Position - Fast aspirating and fast dispensing
L : Low Position - Slow aspirating and slow dispensing
G : Gravity Position - Slow aspirating and dispensing by gravity force only.
It is recommended to choose L position for less volume pipettes up to 5 ml & H position
for volumes greater than 5 ml. The speed of aspirating & dispensing can also be controlled
manually by controlling the nger pressure on trigger buttons. The deeper the button is
pressed, the faster the liquid will be aspirated or dispensed.
Aspirating (Filling the pipette): Slowly press the upper pipetting trigger, the liquid will
start aspirating. Fill the pipette slightly above the mark desired, adjusting the aspiration
speed by nger pressure, particularly in the nal stage. Do not overll the pipette. After
lling the pipette above the desired volume press the lower trigger gently, dispense excessive
liquid from the pipette until the meniscus of liquid aligns exactly with the required volume
mark on the pipette.
Dispensing: Slowly press the lower pipetting trigger. The liquid will start dispensing.
Note: It may happen that during gravitational force dispensing the pipette is not completely
emptied due to the characteristics of pipettes used with the pipette controller.
• Unscrew the nosepiece.
• Pull out the membrane lter and the silicon
pipette holder.
• Rinse the silicon holder which includes a valve
using a wash bottle.
• Blow liquid out of the silicon holder and leave
it until it is completely dry.
• Place the new membrane lter, assemble the
device in reverse order and carry out leak
test.
Note: Only use genuine manufacturer
recommended lters and accessories.
Desktop stand: the pipette controller can hold
a serological pipette while resting on it.

7. Battery Replacement
8. Trouble Shooting
Unlike most of the other common Pipette Controllers, the change of batteries is very simple
with this instrument and can be carried out without exposing the inner mechanism and
circuit. For replacing batteries, rst pull out the 3 mode switch cover as shown in the gure
by applying pressure from its lower side. Now remove the batteries compartment cover by
pressing embossed arrow and simultaneously sliding it back. Remove the batteries. Insert
new batteries and reverse the above procedure. Put the batteries in the compartment and
switch cover back into their original position.
Note: If recommendations in the trouble shooting section do not solve current problems,
contact your authorized dealer.
