We offer wide range of products
with most common grading available on each item. It includes Synthesis
grade, Extra pure grade, GR grade, ACS grade. Grading for special application
such as HPLC grade, Pesticide grade, Electronic grade, Biochemistry grade,
Histology and solvent for Trace Analysis etc.
The purity grade helps us to classify the large variety
of reagents that exist in the market. Purity grade is expressed in the
product name by means of a quality denomination that follows to the product
nomenclature (i.e. "Guaranteed Reagent" or "Extra
Pure"). Several quality denominations are common to all manufacturers
but, in addition, every manufacturer creates its own quality denominations
for specific applications.
The purity levels and physical and chemical values indicated
for the products in this catalogue represent typical values. These percentages
and measures are not norms, nor are they specifications.
There is however a certain number of products for which
we have added a + sign to the quality indication, for example 97%+. For
these products the typical level of purity will be greater than the percentage
indicated next to the name of the substance.
In all other cases, the contents of a batch will be
close to the typical level of purity. And we supply Product Specification
sheets and Certificates of Analysis, as well as MSDS's (Material Safety
Data Sheets) with every order.
IL chemicals have large diversity in grading and types of use summarized
These products are suitable for non-critical tasks in the laboratory such
as rinsing, dissolving or are used as raw materials in production tasks.
Those reagents those are suitable for organic synthesis and preparative
Extra Pure grade
This quality is associated to products that are suitable for qualitative
and semi-quantitiative grades. These chemicals suitable for general laboratory
works, and in most cases, meet Most Pharmacopoeia (BP, USP etc.) Standards.
Products and solutions meeting the purity requirements
of chemical products admitted in the pharmaceutical sector (pharmacopoeia
requirement such as NF, BP, USP, Ph Eur, DAB, DAC, JP, Ph Franc..)
For Analytical Purpose
This quality is suitable for most analytical application,
research and quality control.
It is the ideal quality for laboratory purposes. Batch to batch reproducibility
is specially controlled to guarantee consistent analytical results. The
grade is equivalent to Analytical grade (A.R.) Reagent grade (R.G.),
p.a. nomenclature of other manufacturers.
Reagents meets the specification of American Chemical Society (ACS) Analytical
reagents found in most laboratories and are used in a wide variety of
analytical techniques for quality control, research and development.
Product range is specially made for high performance
liquid chromatography. Within this range there are different qualities
depending on whether they will be used for preparative chromatography
or analytical in isocratic or gradient mode. The range includes high purity
solvents, tested to meet strict UV absorbance specifications as well as
ion pair reagents.
Ion Pair Reagents
Ion pair chromatography is done when the analytes of
interest include ionic compounds that are difficult to separate by reverse
phase chromatography. Ion pair reagents are added to the movil phase and
combine with ionic analytes. The neutral compounds formed can be easily
chromatography by reverse phase HPLC. We offer both cationic and anionic ion pair reagents
in special HPLC grade qualities to assure trouble-free separations.
Pesticide & GC residue
Solvents are specially tested to avoid organic impurities
at ppt levels. These solvents are specially purified in a multi-step process
using only glassware equipment. Inert conditions are kept during bottling
to assure optimum performance and to avoid any possibility of contamination.
Dry & Anhydrous
Solvents with a very low water content, applicable for
analytical purposes or organic synthesis. Dry solvents are traditionally
used in water determinations according to Karl Fischer and anhydrous solvents
are becoming more necessary in the new organic and inorganic chemistry
research techniques. In our catalogue, you can also find extra-dry grade
solvent or extra-dry with molecular sieves.
Peptide and DNA synthesis
The most important features of these products are low
UV absorption and low water content.
Solvents display a high UV permeability and are subject
to strict IR Spectroscopy tests.
Food/ FCC grade
Products meet the strength specifications and maximum impurity limit indicated
in the Food Chemicals Codex (FCC)
Molecular biology reagents
These products are specially controlled to guarantee the absence of enzymes
that could interfere in the analysis and an adequate transparency for
the detection techniques used in molecular biology.
Biotech/ Biochemistry grade
Highly pure reagents suitable for biochemical research and analysis. The
critical parameters involved are absence of inhibitors such as traces
of heavy metals as well as biochemical function tests for enzymes, coenzymes
and enzyme substrates.
We offer hundreds microbiological products with some dehydrated culture
media auxiliary agent and other manual systems in its range.
Our fluorescence HPLC grade is gradient and fluorescence controlled. It
is specially suitable for PAH analysis by HPLC
IL offers various types of chemicals and reagents for microscopy use.
Specially stabilized Tetrahydrofuran is available for GPC (gel permeation
chromatography). This THF can be used for column-storage, since it does
not form damaging peroxoides.
Cell Culture grade
IL cell culture reagents include cell culture media, laboratory preparations,
biological extracts, selective and sterile reagents for several applications.
Proteomics defined as the qualitative and quantitative comparison of proteomes
under different conditions to further unravel biological processes, we
offer reagents for these usage.
IL offers solvents and reagents purity meets the histological uses.
Ultra pure grade
IL Ultra pure reagents are used in inorganic trace analysis
where impurities must be low in the ppt or ppb level. Each reagent is
delivered complete with a lot analysis certificate.
VLSI/ ULSI/ SLSI grade
Reagents used for semiconductor industry, cations, anions
and particles value guarantee to ppm to ppb level. Our range of chemicals
covers all products required in cleaning and etching processes for semiconductor
In the analysis of oil derivatives it is of interest that the reagents
and apparatus are manufactured under the American Society of Testing and
Acids with low mercury content
These acids are used in environmental analysis when analyzing traces of
mercury, and assure that no interferences are added to the samples because
of the acids.
AA and ICP standard solutions 1000ppm
They are made out of high-purity salts and acids, or bases. The accuracy
of its concentration is checked by using titrimetric and gravimetric methods.
These solutions can be used in atomic absorption spectroscopy, polarography
or colorimetric techniques. They are traceable to NIST with certificate
Ready to use volumetric solutions and most of them are traceable to NIST.
pH buffer solution
IL offers a broad range of ready to use buffer solutions
for pH-meter calibration. They are accurate and traceable to NIST. Colored
solution of pH 4, 7, 10 available for easy differentiation.
Karl Fischer reagent
Karl Fischer titration is widely used to quantify water
content in many different samples. It is used both in industrial processes
and in quality control laboratories. Our KF reagents are pyridine-free,
which contain non toxic imidzole. It has a good buffer capacity and allows
fast and stable titration end-points
