Frequently Asked Questions

Nichipet EXⅡ

Q. I wish to know the price and AC/CV for products.
A. Please look at Products Nichipet EXⅡ.

Q. Can the pipette be used with organic solvent?
A. The normal O-ring which is usually installed in the pipette can be resistent of some organic solvents, but it may expand depening on solvent you are using. In case that you are frequent user for organic solvent, value-added Nichipet EX Plus Ⅱ will be recommened. Please contact Nichiryo for chemical compatibility since there is such solvent as N-methylpyrrolidone which cannot be used. In case that you are using volatile liquid, the pipette mechanism will allow air come in, thus causing pressure going up and may lead to the leakage.

Q. What is the material of plunger?
A. Stainless for NPX2-2,10,20 and 100. Ceramic for NPX2-200,1000,5000 and 10mL.

Q. How about the chemical resistance for pipettes without ceramic plungers?
A. SUS316 stainless plunger are used. Nichipet EX PlusⅡ will be recommended for frequent users for organic solvent.

Q. Can non-nichiryo-made tips be used ?
A. To maximize the pipette performance of AC/CV, Nichiryo-made tips will be recommended. But you can stil use other tips than Nichiryo. Please see below.

Q. Is there no risk of trapping gloves?
A. Digital pipettes with push button have no risk of trapping gloves.

Q. Can the pipette be cleaned with alcohol?
A. No problem.

Q. Does the volume once set up drift?
A. The locking system will not allow the drifting.

Q. Does oversucking into the inside of the pipettes happen?
A. Larger volume pipettes have filters to avoid the oversucking. Pipettes below 200UL are less likely to oversuck.

Q. I wish to know the price for replaceable spare parts like nozze cylinder.
A. Please see the list of replaceable spare parts.

Q. Tip cannot be ejected out. Is this defect?
A. Nozzle cylinder may be loose. Please read User Manual enclosed and tighten the nozzle.

Q. The pipette cannot suck the liquid. The pipettes cannot dispense the volume.
A. The nozzle cylinder may be loose, so please tighten it. O-ring/Seal ring may also be exhausted. Please see filters in pipetttes over 1000ul. In case that filters are wet , please change this into new one. Defects due to other reasons than the abobe mentioned two things will be reapaired in Nichiryo workshop.

Nichimate Stepper

Q. I wish to know the price and the specification for AC/CV.
A. Please see Products Nichimate Stepper.
Q. Will sylinges for Eppenforf 4870 be fitted into Nichimate Stepper ?
A. Yes, they will. But they will not with 4980.
Q. Will sylinges for Nichimate Stepper be fitted into Eppendorf 4870 ?
A. Yes, they will.
Q. Are sylinges for Nichimate Stepper used in commom with Model 8100 ?
A. No, they aren't. Connector and piston head are different.
Q. How many sylinges are avaolable ?
A. We have 8 kind. 0.05, 0.5, 1.25, 2.5, 5.0, 12.5, 25 and 50ml.
Q. Can sylinges be autoclavable ?
A. No,they can't.
Q. Are sterilized syringes available ?
A. We have 5 kind.

Code Volume range nubmer packed.
NS-SB 0.50ML 100
NS-MB 1.25ML 100
NS-NB 250ML 100
NS-LB 5.00ML 100
NS-XB 12.50ML 100
Q. Can attachment be autoclavable ?
A. Yes, it can. It is made of polypropylene.
Q. Is there any risk of sylinge going out of the body during dispensing ?
A. As long as the sylinge is fixed by lock handle, it would not come off from the body.

ACCUPENSER JR.

Q. Can it be autoclavable？
A. Yes, it can. On autoclaving it, please keep the bottle closed. Please also keep the bottle empty. Liquid would have been boiled.
Q. Does AJ-5(5ML) fit with 1L bottle？
A. Yes,it does. Please contact dealers to identify the size of bottles you need.
Q. Do AJ-2 and AJ-10 fit with 2L bottle？
A. Yes, they do with buying optional adaptors. 2L bottle will be taller than 500ml and 1L bottle, so the main units may not reach the bottom of the bottle. You can buy the optional PTFE tube in such case that liquid is getting less.
Q. Can the liquid be added while the main unit is set with the bottle？
A. Yes,it can. Please remove the small cap on the lid of the bottle and add the liquid very carefully using the funnel enclosed.
Q. I wish to dispense the liquid to the place a bit far from the bottle.
A. Please use the extension silicone tube. It is 60 cm long.
Q. Is this tube chemical-guard？
