Prepared Reagents for Volumetric Analysis (Normal Solution)
Reference Materials for Volumetric Analysis
TraceSure Series are certiﬁed reference materials that have obtained ASNITE（Accreditation System of National Institute of Technology and Evaluation)（Guide 34）at Wako
from International Accreditation Japan (IAJapan) by the Accreditation Program.
Indicators
Highly versatile indicators and indicator solutions are readily available, centering around titration indicators listed in JIS K8001.
Standard Buﬀer Solutions
Wako has been qualiﬁed as an institution for calibration (licensed trader) of standard pH solutions, standard metal solutions and standard ion solutions by the Minister of Economy,
Trade and Industry and oﬀers the standard solutions traceable according to the National Metrology Standard. These products areprovided with acalibration certiﬁcate marked
with JCSS to certify that it is traceable according to the National Metrology Standard and, at the same time, attests to the supply of accurate and highly reliable reagent.
Reagents for Electrode
In potentiometric titration, polarographic method, controlled-potential electrolysis, pH measurement (by glass electrode), etc., calomel electrodes, silver-silverchloride electrodes,
and other electrodes are used for reference electrodes. As the electrolyte solution of reference electrodes such as calomelelectrodes, silver-silver chloride electrodes,
etc., a potassium chloride solution of a predetermined concentration is used. In addition, the potassium chloride solution is used for the electrode preservation solution, too.
Reagents for Colloidal Titration
The colloidal titration method is titrimetry for simply determine the polymer electrolyte by titration. In general, colloids having positive or negative electric charges
stoichiometrically react with colloids having opposite electric charges and form a sparingly water-soluble precipitation. In the event that the positive colloid is determined by theuse of this principle, the solution is titrated with the normal solution of potassium polyvinyl sulfate (PVSK) having a negative electric charge. Toluidine blue of the indicator is abasic dyestuﬀ having -NH2 and is not absorbed by the positive colloid, showing an original blue color, but when it encounters with a negative colloid, toluidine blue is immediately
absorbed and assumes a red-purple color. The equivalent point of the reaction is, therefore, able to be simply and highly accurately detected.
Reagents for Non-aqueous Titration
In the event that an acid and a base are too weak to be titrated in an aqueous solution, they are titrated in an appropriate nonaqueous solvent.
A wide range of solvents, standard solutions, and indicators are lined up for nonaqueous titration.
TraceSure
TraceSure Series product is the certiﬁcated reference material which has acquired a certiﬁcate of reference material producer by ASNITE certiﬁcation program of National
Institute of Technology and Evaluation, IAJapan. The certiﬁcate with the uncertainty of proof of the reliability is attached to each product.

Trade and Industry and oﬀers the standard solutions traceable according to the National Metrology Standard. These products are provided with a calibration certiﬁcate marked
with JCSS to certify that it is traceable according to the National Metrology Standard and, at the same time, attests to the supply of accurate and highly reliable reagent.
Karl Fischer Reagents [Mitsubishi Chemical Corp.]
Karl Fisher method uses Karl Fischer reagent, which reacts quantitatively and selectively with water, to measure moisture content. Karl Fischer reagent consists of iodine, sulfur
dioxide, a base and a solvent, such as alcohols. This method can be used in both coulometric and volumetric titration systems.

Reagents for Atomic Absorption Spectrochemical Analysis
Atomic absorption spectrochemical analysis is used for determination of trace metals. Because of high sensitivity, high selectivity, and easy operation, atomic absorption
spectrochemical analysis is an important analysis method of heavy meals in water, soil, and biological samples.
As reagents used for atomic absorption spectrochemical analysis, high-quality pretreatment reagents of acids, alkalis, etc. and metal standard solutions with extremely little
content of heavy metal impurities are readily available.

Trade and Industry and oﬀers the standard solutions traceable according to the National Metrology Standard. This product is provided with a calibration certiﬁcate marked with
JCSS to certify that it is traceable according to the National Metrology Standard and, at the same time, attests to the supply of accurate and highly reliable reagent.
Multielement Standard Solutions for ICP Analysis
These products are mixed reference standards for trace elements analysis by ICP (Inductively Coupled Plasma).
Reagents for Analysis of Poisonous Metals
Hg, Cd, Pb, As and other poisonous metals as environmental pollutants are measured at the ppb level by increased sensitivity of atomic absorption spectrometer, ICP emission
spectral analysis/ICP mass spectroscope, etc. Reagents for analysis of poisonous metals are reagentswith impurity metal content reduced to the maximum as reagents which aremeasured against these poisonous metals.

Super Special Grade Reagents (S.S.G.)
Super special grade (S.S.G.) reagents are reagents with the highest quality standard guaranteed for which speciﬁcation parameters and speciﬁcation values of JIS special gradeor higher are speciﬁed.
Reagents for Ultratrace Analysis■Each product guarantees the content of various metallic impurities at the ppt level.
■In order to maintain the ppt-level quality for using ﬂuororesin (PFA) containers (extra-pure water uses high-density polyethylene containers), PFA containers thoroughly cleaned
before ﬁlling is used.
■Double plastic bag packing used: Because single plastic bag (inside) packing is performed in the clean room, the reagents are able to be carried into the clean room as it is.
■Inspection report attached: Impurity metal analysis by ICP-MS and FL-AAS is performed, and the analysis results are attached to the product.
Highly-Pure Reagents for Electronic Industries
High-purity organic solvents and acids for electronic industry.
They are applicable to semicondenser ﬁeld and have low contents of particles and metal impurities.
Inﬁnity Pure Series (∞Pure)Inﬁnity Pure is a series of reagents characterized by the highest quality and small packaging unit (100 mL). The reagents, particularly those in the biochemical ﬁelds such as geneengineering, immunology and cell biology, are required to be highly puriﬁed with little secondary contamination after opening the package. This product is available in the packageof 100 mL minimizing unused waste and it is a personal reagent with a space for recording the opening date, user name, etc. in the label.

Shift Reagents
Shift reagents improve separation of signals making the best of the properties that the NMR peak positions are shifted. Adding these reagents can separate signals and facilitate
the analysis.
Internal Standard Reference Materials
This is an internal standard reference material added to the NMR solvent when NMR is measured and is used for determining the shift positions of other peaks.
NMR Test Tubes
NMR test tubes are high-quality reasonable NMR glass tubes. There are S (standard) type used for the routine and HG (high-grade) type with smaller outside diameter and suitedfor measurement in the high-frequency region. In addition, the total tube length is available in two sizes, 7 inches and 8 inches, so that the tubes can be chosen to ﬁt tomeasurement instruments used.

Wetting tension test mixtures are used for plastics -ﬁlms and sheets- in order to test the wetting tension. It is prescribed in JIS K6768.

Each solution is a standard solution prepared in response to the request from the International Cooperative Study of the Kuroshio and Adjacent Regions (CSK). CSK standard
solutions were shared marine samples prepared to achieve the integrity of analysis of nutrient salts in seawater. No preservative is contained but the solutions are sterilized.

Wetting Tension Test Mixtures■ Wetting Tension is …
The ability of plastic ﬁlms to retain inks, coating, adhesives, etc., is primarily dependent on the character of their surfaces, and can be
improved by one of several surface-treating techniques. These techniques have been found to increase the wetting tension of a plastic
ﬁlm surface in contact with mixtures of solvents. It is therefore possible to relate the wetting tension of a plastic ﬁlm surface relates to its
ability to accept and retain inks, coatings, adhesives, etc.
The condition with water drops placed on the surface is not deﬁned to be wet (Fig. 1). To let the surface get wet with a liquid with strong
surface tension as in the case of water, the ﬁlm surface must have the property to blend into water (high polarity). Conversely, with thesolvent with weak surface tension as in the case of organic solvent, the ﬁlm surface gets wet even if the ﬁlm surface has a property to repel water.
Consequently, when plastic ﬁlm is coated with paint, provided with coating, or bonded, it is important to know the wetting tension of plastic ﬁlm.
（Prescribed in JIS K6768.）（Fig.1）（Fig.2）

Wet■Principle

Not wetNot wetA series of mixtures of solvents of gradually increasing surface tension are applied to the surface of the plastic ﬁlm until a mixture is obtainedthat just wets the ﬁlm surface. The wetting tension of the surface under test is approximately by the surface tension of this particular mixture.

A cotton-tipped stick is used for spreading the test mixtures and the liquid shall be spread rapidly over an area of at least 20 cm2. The
quantity of liquid shall be such that it forms a thin ﬁlm without pools. Impregnate the mixture and apply only one coat to the ﬁlm in thelateral direction. The amount of the liquid applied exerts great eﬀect on the accuracy of the test, to which care must be taken.
〇 In the case of excess application
The liquid ﬁlm does not break from the ﬁlm inside but shrinks from the surrounding, and forms a large liquid drop (large measurement value results〇 In the case of application of an appropriate amount

Breakage of coated liquid ﬁlm simultaneously occurs not only from the surrounding but also the center part of the ﬁlm〇 In the case of application of excessively small amountIn the case of application, breakage of liquid ﬁlm occurs in the direction where the cotton-tipped stick is moved and application irregularity is formed (small
measurement value results).

■How to determine
Observe the liquid ﬁlm of the test mixture under glancing illumination and note the time taken for the continuous liquid ﬁlm to break
up into droplets. If the liquid ﬁlm holds together for more than 2 seconds, repeat the test on a new pecimen with a mixture of the next
higher surface tension, until the liquid ﬁlm breaks up in less than 2 seconds. If the liquid ﬁlm holds for less than 2 seconds, proceed tolower surface tensions until the ﬁlm persists for 2 seconds. (Fig. 2)
