SMART PIPETTE - USER GUIDE
Raw Material
The SMART pipette is made of mechanically robust and chemically
resistant materials, making it a durable and stable pipette giving
consisting performance for long time.
Digital Display
In SMART pipette, delivery volume is evidently indicated in the large
digital display on the handle.
In variable volume pipette, the last wheel of the counter has a
scale that assists to set precise delivery volume.
In some of the variable volume pipettes the last one or two counter
wheels will be in grey color which indicates the value after decimal.
A pointer is used to set exact or intermediate volumes with the help of
scale on last wheel.

PIPETTE OPERATION
Setting the Volume
With the SMART pipette, the delivery volume of liquid is set using the
digital counter. A pointer is used to set exact or intermediate volmes
using the scale on the last wheel of digital counter. In some of the
variable volume pipettes, counter wheels are in black & grey color.
Grey wheel indicates value after the decimal.
You can set the delivery volume
using the volume changing knob
on the upper side of pipette after
unlocking the counter by pulling
up the counter lock. To decrease
the delivery volume, turn it
clockwise and to increase, turn
it anti-clockwise. Do make sure
that the desired delivery volume is
set in-line with pointer. Pull down
the lock to ensure that volume
doesn’t accidently changed during
pipetting.

1) Counter lock mechanism is to ensure volume changing knob remains in its
position while aspirating or dispensing liquids. Any forced efforts to rotate the
volume changing knob while counter lock mechanism is in lock position will either
make it in unlock position or may damage the locking mechanism.
2) Setting the volume beyond the specified volume range is not advisable. Using
excessive force to turn the volume-changing knob outside the specified range,
may jam the mechanism and eventually damage the pipette.

SMART PIPETTE - USER GUIDE
Loading and Ejection Tips
Each SMART pipette is fitted with a tip ejector which helps eliminate
safety hazards associated with contamination.
It is necessary to check that the tip cone is clean before fitting a tip.
Press the tip on the cone of the pipette firmly to ensure an airtight
seal. The seal is set tight when a visible sealing ring forms between
the tip and the tip cone.
The tip ejector needs to be pressed downwards firmly with the thumb
to ensure proper tip ejection. Once the process is complete, make
sure that the tip is disposed of into a suitable waste container.
PIPETTING GUIDELINES
•While using the pipette make sure that operating knob has been
handled slowly and smoothly.
•Ensure that the tip is firmly attached on the tip cone. Please check
for foreign particles and remove if any, around the tip cone.
•Make sure that the temperature of tip, pipette and liquid are at
equilibrium.
•While holding the pipette, its main handle should be resting on your
index finger.
•While aspirating, hold the pipette in upright position and keep the
tip at a constant depth below the surface of the liquid.
•You should pre-rinse the tip before aspirating the liquid by filling
and emptying the tip 5 times. This is important especially when
dispensing liquids, which have a viscosity and density different
from water.
•For the volatile solvents you should saturate the air-cushion of your
pipette by aspirating and dispensing the solvent repeatedly before
aspirating the sample.
•When pipetting liquids with temperatures different to the ambient
temperature, pre-rinse the tip several times before use.
•After pipetting acids or other corrosive liquids that emit vapors,
remove the tip-cone and rinse the piston, O-ring and seal with
distilled water.
•Do not pipette liquids having temperatures above 70°C or below
4°C.
Make sure that liquids never enter the tip-cone, to prevent this:
•Never lay the pipette on its side when there is liquid in the tip.
•Press and release the push knob slowly and smoothly.
•Never turn the pipette upside down

Forward Pipetting
1. Press the operating knob to the first stop.
2.Dip the tip under the surface of the liquid in the reservoir to a depth
of about 1cm and slowly release the operating knob. Withdraw the
tip from the liquid touching it against the edge of the reservoir to
remove excess liquid.
3.Dispense the liquid by gently
pressing the operating knob to
the first stop. After a delay of
about one second, continue to
press the operating knob all the
way to the second stop. This ac-
tion will empty the tip.
4. Release the operating button to
the ready position. Change the tip
and continue pipetting.

Reverse Pipetting
The reverse technique is suitable for dispensing liquids that have
a high viscosity or a tendency to foam easily. The technique is also
recommended for dispensing very small volumes.
1. Press the operating knob all the way to the second stop.
2.Dip the tip under the surface of the liquid in the reservoir to a depth
of about 1cm and slowly release the operating knob. This action
will fill the tip. Withdraw the tip from the liquid touching it against
the edge of the reservoir to
remove excess liquid.
3.Deliver the preset volume by
gently pressing the operating
knob to the first stop. Hold the
operating knob at the first stop.
Some liquid will remain in the tip
and it should not be dispensed.
4. The remaining liquid should
either be discarded with the tip
or should be dispensed back into
the reagent reservoir.

SMART PIPETTE - USER GUIDE
CALIBRATION AND ADJUSTMENT
All SMART pipettes are been quality tested according to ISO8655/DIN
12650. The quality control according to ISO 8655/DIN 12650 involves
gravimetric testing of each pipette with distilled water (quality 3, DIN
ISO3696) at 25°C +- 1° C.
All SMART pipettes are been calibrated in ISO/IEC 17025 accredited
laboratory. Each Pipette is calibrated, inspected and validated by
qualified technicians according to defined quality system.
SMART pipettes are constructed to permit re-adjustment for other
pipetting techniques or liquids of different temperature and viscosity.
Devise requirements and test conditions
An analytical balance must be used. The balance selection depends
upon selected model of the pipette and sensitivity of balance reading.
Test liquid: Water, distilled or deionized, grade 3 water conforming
ISO 3696.
Calibration should be carried out in a draft-free room at a constant
(+- 0.5°C) temperature of water, pipette and air between 15°C to 30°C.
The relative humidity must be above 50%, especially with volumes
under 50ul, the air humidly should be as high as possible to reduce
the effect of evaporation loss.
Special accessories for analytical balance, such as the evaporation
trap are recommended for the calibration of volumes under 50ul.

MAINTENANCE
When the SMART pipette is not in use, please make sure that it is
stored in an upright position. Accumax recommends the SMART
stand for this purpose.
You should check the pipette at the beginning of each day for accu-
mulation of dust and dirt on the outside surfaces. Attention should
be paid to the tip cone. No other solvents except Iso-propanol should
be used to clean the pipette. If the pipette is used daily, it should be
inspected every three months.
The servicing procedure starts with the disassembly of the pipette.
Please refer to the spare parts lists for better understanding of the
components. Shown here is an example of dis-assembly and as-
sembly procedure of 100-1000 µl pipette, the basic procedure is to be
followed for all other volume pipettes.
