  About Us : Quality Designations

GUARANTEED REAGENTS (GR): Reagents useful for analytical purpose and research work where high purity is essential. The certificate of guarantee give the minimum assay and maximum limits of trace impurities.

This is similar to grade marketed by other international company as:

FOR SYNTHESIS: General purpose reagents used in many potential applications in chemical laboratories. Careful control ensures that a consistently high defined quality is maintained throughout.

LABORATORY REAGENTS (LR): Pure, Extra Pure, Purified :
Purified commercial products used in many commercial laboratories.

HPLC GRADE: continuing advances in the use of HPLC have lead to increased demand for solvents and reagents in wider range of application areas, particularly for biomolecular and ion separation. Key parameters such as UV absorbance, transmittance, non-volatile matter, moisture content, fluorescence impurities and assay are very carefully controlled.

SPECTROSCOPY GRADE: These are solvents of high optical purity for UV / Visible / IR / Fluorescence / NMR and Mass spectroscopy. The certificate of guarantee includes assay, minimum transmission at certain defined wavelengths in UV range, moisture content, non-volatile matter etc.

DIAGNOSTIC REAGENTS: These are specially produced for the use of various hospitals, clinical & pathological laboratories for diagnostic purpose.

BIOLOGICAL STAINS: These chemicals are provided as power and ready to use solutions for Microbiology, Histology, Haematology and Cytology, stringent testing on all batches is performed to ensure al specifications are satisfied. They correspond normally to the specifications given in H.J. Conns Biological Stains (1977).

BIOCHEMICALS: Highly purified reagents for the use in biochemical research and analysis. They are free from inhibitors such as traces of heavy metals and tested with a view of biochemical work. Our range includes alkaloids amino acids, buffers, carbohydrates, enzymes, enzyme substrates nucleotides and derivatives etc.

FOR MICROBIOLOGY: A broad range of culture media bases, additives, stains and indicators for use in detection, growth and identification of microorganisms.

FOR ION PAIR CHROMOTOGRAPHY: Highly pure additives for ion pair chromatography are suitable for detection in low UV range. Reagents of this special quality inspected by means of a filter test, a cyclovoltagram and gradient test at 205 nm.

GEL ICE PACKING (48 Hours): Temperature sensitive packing available. Packing & Freight charges additional.
