Quality Designation

BIOLOGICAL STAINSThese 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 all specifications are satisfied. They correspond normally to the specifications given in H. J. Conns Biological Stains (1977).

BIOCHEMICALSHighly purified reagents for 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.

MOLECULAR BIOLOGY GRADE (MB)To meet the requirements of our Molecular Biology customers in the Life Sciences Sector we are expanding our Molecular Biology performance grade product line. These products are prepared specifically for Molecular Biology usage and are certified to be DNase-, RNase-, and protease-free.

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

ANALYTICAL REAGENTS (AR)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 : Analar, P.A. (Proanalysis) GR, (Guaranteed Reagent), Puriss.

ACSMeets the American Chemical Society Standards.

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

EXTRA PURE (EP)Laboratory reagents pure, Purified commercial products used in many chemical laboratories.

HPLC GRADEContinuing advances in the use of HPLC have lead to an 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.

GC GRADEAs more sensitive capillary GC methods are introduced, solvent purity must be improved to meet the more stringent analytical requirements. According to this, GC Grade solvents have evolved, which are extremely high-purified solvents. To guarantee our tight specifications we perform strict GC quality controls. After strong concentration of the solvent, differences in quality are easily revealed.

SPECTROSCOPY GRADEThese 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 REAGENTSThese are specially produced for the use of various hospitals, clinical and pathological laboratories for diagnostic purpose
