Nichipet EX II
Digital micro pipette for liquid handling
Features
● Nichipet EX II is fully autoclavable at the condition of 121°C for 20 minutes.
● Nichipet EX II is made of UV resistant material which can be used in clean bench.
(If UV is applied to Nichipet EX II for a considerably long time, it may become discolored but
nothing affects its performance.)
● New round shape improves friendly handling capability, and mitigates operator’s fatigue from
long time use.
● Sample volume can easily be set by simply rotating the push button.
● Setting of sample volume can easily be locked with one touch (one-touch lock mechanism).
● A wide range of sampling volume can be covered by eight models from 0.1ul to 10,000ul.
● Patented body construction avoids permeating hand temperature through the body that
prevents inaccuracy of volume measurement.
● Since PTFE (Fluoroplastic) is used in an airtight chamber, this combination keeps airtight and
precise reproducibility for long hours.
● A thin nozzle corn can be easily inserted and reached to a bottom of many tubes for
dispensing/aspiration. (110mm in depth, 2ul – 1000ul)
● Tip can be removed without touching by using the tip ejector.
● The Easy-Calibration function provides smooth and easy adjustment with an attached
adjustment tool.

Please read following prior to use for your safety and correct usage.
CAUTION
Be sure to observe the following instructions for using Nichipet EX II
properly and safely.
If user misuses “Nichipet EX II”, or disregards the following instructions, it may result in injury to
the user or/and other persons or physical damage to pipette or/and other equipment.
1. Do not use pipette for any purpose except pipetting/dispensing liquid.
2. Do not modify pipette, because modification may cause an accident.
3. Do not use pipette for pipetting any liquid to be injected into human body.
4. Do not expel dispensed liquid towards anybody.
5. Do not eject tip towards anybody.
6. Do not eject tip with liquid inside.
7. Carefully handle pipette and tip because tip is sharply pointed.
8. If pipette is contaminated with liquid harmful to human, immediately take appropriate
disposal to clean it safely before continuing to work.
9. Do not use pipette for stirring liquid and so on, otherwise not only tip may be loose and
fall off but the pipette may be soiled with scattered liquid.
10. Do not touch filters which may be contaminated by harmful substances.
11. Take extreme care for sharpness of Nozzle filter remover when filters for 5000 ul or
10000ul types are taken off.
12. Do not touch pipette directly right after drying, because it will have got very hot during
drying. Touching hot pipette directly may cause injury.
13. Components of water used for autoclave may cause pipette malfunction or performance.
14. If pipette can not be fixed after examining and conducting in accordance with designated
procedure, immediately stop using the pipette and ask us or our agent to repair it.
15. For organic solvents, Nichipet EX Plus II (NPLOII) will be recommended to use.
16. Although this pipette has good chemical-resistance in general, it may be damaged by
some kinds of chemicals. Please contact to our company when using strong chemicals.
17. Pipette can be used between +4°C and +40°C, but the specifications may vary.
18. Depending on frequency of use, pipette should be cleaned in a soap solution and airtight
chamber should be maintained according to this manual.

Note
Users are required to strictly observe the followings in order for the
pipette to keep its excellent precision, reproducibility and original
performance for a long time.
1. Do not expose pipette directly to the sun when working with it or for 2 hours before
starting work, otherwise the pipette may lose accuracy. Avoid working with pipettes in a
humid and hot place.
2. Just before starting work with pipette, avoid touching tip and nozzle cylinder as far as
conditions are allowed. If nozzle cylinder is warmed by your hand, accuracy may vary.
3. For pipetting, follow the forward method (the way explained in this manual). If it is
performed in a different way, it may result in inaccurate pipetting.
4. Operate push button very gently. If it is quickly released, it may result not only inaccurate
pipetting but also deteriorated the pipette because sample liquid may be permeated into
the main body. To prevent the pipette from malfunction, inaccuracy and contamination, a
filter is attached to models NPX2-1000, -5000, and -10000. (A filter is supplied at time of
purchase.)
5. Do not reuse tip that has been used once, and carefully dispose used tip. If tip is used
repeatedly, it may cause inaccurate and impure pipetting and cross contamination (*)
among samples.
* For example, if previous sample liquid is left inside tip, it is mixed with new sample liquid
and the new sample is contaminated by the previous one. Therefore, pipetting of the
next sample results wrong. This phenomenon is called mutual contamination of samples.
6. Do not hold pipette horizontally or upside down when there is liquid inside tip, otherwise
the liquid gets into the main body and the pipette may be contaminated.
7. When autoclaving, do not pile pipettes on others in the autoclave or lean pipettes with a
nozzle top facing down so that self-load is applied on the nozzle. This pipette is made of an
autoclave compatible material, but because of high temperature in the sterilizer, there is a
risk that parts subject to load will be deformed.
8. After autoclaving and drying pipette, leave it until it gets completely cool before using
again. If the pipette is used when warm, the accuracy may not come up to the standard
level.
9. After autoclaving and drying pipette, assemble the pipette after it is completely cooled, if it
is assembled when it is still hot, it may cause deterioration in the pipette such as breakage
of the screw threads.
10. When rotating push button, do not exceed the specified sample volume limit, otherwise
pipette may be damaged or deteriorated.
11. Do not perform pipetting with less liquid than set volume. If the quantity of liquid is less
than the set volume, it may cause the liquid to scatter into the main body and the pipette
may deteriorate in quality.

4. Recommendation for accurate pipetting
In addition to the above mentioned operations of pipetting, the following procedure maximizes
performance of pipette.
1) Make sure that tip is firmly attached to nozzle end.
2) Before pipetting, pre-rinse the tip by filling and expelling the tip for three to five times. It
gives good precision of pipetting, especially with a viscosity or a vaporous liquid.

3) Especially with volumes under 50ul, the operation should be done very slowly and
smoothly and the air humidity should be as high as possible to reduce the effect of
evaporation loss.
4) Sampling high density liquids and viscous solutions.
When aspirating, once the liquid has entered the tip, wait 2 to 3 seconds before removing
the tip from the surface of the liquid. When dispensing, wait 2 to 3 seconds at the first
stop position before pushing to the second stop position.

- 5000ul, 10000ul : Fig.G4, G5
Remove the seal spring, the O-ring retainer, the O-ring and the seal ring from the nozzle
cylinder.
Note: Shapes of the O-ring retainer are different by size of pipette.
Note: Pay attention to small parts for not loosing them during disassembling.
-9-
2. Reassembling
① Reassemble nozzle cylinder.
- 2, 10, 20ul : Fig. G1, 100, 200ul : Fig G2, 1000ul : Fig G3
Firstly, set 1st spring on plunger, next set O-ring retainer, seal ring and O-ring in this order.
Then, insert assembled plunger into nozzle cylinder and screw it into the body.
- 5000ul: Fig. G4, 10000ul : Fig. G5
Set volume setting below 30% of maximum volume. Assemble the seal ring, the O-ring and
the O-ring retainer together, and place it on the seal spring(Fig. H-(1)). Place O-ring side on
the ground, and insert the plunger into the seal spring until the O-ring is fully inserted. Take
extreme care not to bend or twist the seal ring when inserted to the plunger(Fig. H-(2)). Put
the nozzle cylinder over the plunger with the seal spring, the seal ring, the O-ring retainer and
O-ring, and screw securely to the lower body(Fig. H-(3)).
Note: For 1000ul, 5000ul and 1000ul, make sure the seal ring and the O-ring are
securely assembled. Strained or twisted seal ring or O-ring may cause
leakage.
Note: When screwing into the body, make sure that the nozzle cylinder and the
body are in vertical direction, and screw the nozzle cylinder into the body
very gently. If not, it may cause leakage.
Note: When reassembling, be careful not to put the seal ring and O-ring in the
wrong order. If the order is wrong, it may cause not only leakage but also
inaccuracy, failure in extracting liquid, etc.
②Fit the ejector pipe to the body.

Autoclaving
This pipette is autoclavable. When autoclaving, carry it out at 121°C for 20 mimutes following
the procedure mentioned below.
① For the 1000 ul, 5000 ul and 10000 ul types, remove the filter referring to the “Filter
replacement procedure” mentioned on P16.
② Release the lock lever from the locked position and set the counter graduation to the
allowable limit of the liquid volume.
③ After autoclaving is complete, dry the pipette completely.
Note: When autoclaving, don’t pile pipettes on others in the autoclave or lean
pipettes with a nozzle top facing down so that self-load is applied on the nozzle.
This pipette is made of an autoclave compatible material, but because of high
temperature in the sterilizer, there is a risk that parts subject to load will be
deformed.
Drying the pipette
Dry the pipette immediately after autoclaving is complete. It is necessary to dry the pipette with
a constant temperature air-drier at 60°C for 60 minutes or longer.

Turn the nozzle cylinder counterclockwise by two and a half turns to loosen it.
Put the pipette in a constant temperatures air-drier for drying.
After the pipette is dry, wait until it returns room temperature and then fasten the nozzle
cylinder and reassemble the ejector pipe into the body.
Note: If the pipette is reassembled when it is still warm, it may cause breakdown or
deterioration of the pipette such as breakage of the screw threads, etc. Be sure
to reassemble the pipette after it has completely cooled down.
If the pipette is used when it is warm, accurate liquid handling can not be
carried out.
CAUTION
: Don’t touch the pipette directly right after drying, because it will have got
