AR : Analytical Reagent (high purity grade)
LR : Laboratory Reagent ( second Purity grade)
CP : Chemically Pure
OR : Organic Grade
AR
: (ANALYTICAL REAGENT) : Reagents essential for
analytical purpose and research work having high purity. The certificate of guarantee give the minimum assay
and maximum limits of trace impurities. These reagents complies maximum tests
of ACS grades, GR , ANALAR , P.A. (Proanalysis) which are marketed by other
international companies.
FOR
SYNTHESIS : General purpose reagents having many potential
applications in laboratories.
LR
: (LABORATORY REAGENTS) : This grade consists of Pure ,
Extra Pure , Purified organic and inorganic chemicals having reliable accuracy
in Routine Laboratory Analysis.
EP
, EXTRA PURE , PURIFIED , PURE : Products suitable for qualitative
and semi- quantitative work. Most of our “extra pure” products comply with
“Pharmacopoeia” grades of all countries and preferentially used in the
Pharmaceutical industries.
CP
: CHEMICALLY PURE : Chemicals being used for
regular practical having its original purity.
MICROSCOPY
(M.S.) : Highly purified Reagent for use in biochemical
research and analysis. They are free from inhibits such as traces of heavy
metals and tested with a view for biochemical work.
HPLC
GRADE : This grade includes solvents, ion pair reagents and
buffers of appropriate purity to be used as mobile phases in HPLC. Our solvents
undergo highly efficient distillation, solid phase absorption and other
chemical treatments. This allows us to eliminate impurities that could
interfere in HPLC analysis. We carry out intensive quality control by means of
UV spectroscopy,
SPECTROSCOPY
GRADE : Nuclear magnetic resonance spectroscopy is the most
commonly used technique in the structural analysis of compounds obtained by
organic synthesis. It normally requires the sample to be dissolved in a solvent
whose hydrogen atoms have been replaced with deuterium atoms. We offers
deuterated solvents of differing isotopic purities. The most usual is 99,8% but
we also have purities of up to 99.98%.
