Let's Explore Chemicals & Solvents
Types of Chemicals & Solvents We Serve (By Application & Grade):
Analytical Reagents (AR Grade)
High-purity chemicals used for precise analytical work such as HPLC, UV analysis, and titrations. These reagents ensure accuracy, reliability, and consistency in critical laboratory applications.
Brands: Merck, Sigma-Aldrich, Thermo Fisher, Avantor/JT Baker/Rankem, Loba Chemie, CDH, SDFCL, SRL, Spectrochem, Qualiagen, HiMedia
Examples: Sodium hydroxide (AR), HCl (AR), Potassium iodide (AR)
​
Laboratory Reagents (LR Grade)
General-purpose reagents suitable for routine laboratory experiments where extremely high purity is not required. Ideal for education labs, qualitative analysis, and basic testing.
Examples: Common acids, bases, salts, indicators
​
HPLC / Spectroscopy Grade Solvents
Ultra-high-purity solvents designed for chromatography and spectroscopy, ensuring minimal interference and maximum resolution during analysis.
Examples: Methanol (HPLC), Acetonitrile (HPLC), Water (LC-MS grade)
​
GC / GC-MS Solvents
Low-residue, highly purified solvents ideal for gas chromatography, enabling stable baselines and accurate detection even at trace levels.
Examples: n-Hexane (GC), Dichloromethane (GC-MS)
Dry Solvents / Anhydrous Solvents
Water-free solvents used for moisture-sensitive reactions in organic synthesis and specialty chemical work. They ensure reaction efficiency and prevent unwanted side-reactions.
Examples: Anhydrous THF, Dry Diethyl ether, Anhydrous Acetonitrile
Biochemical / Molecular Biology Reagents
Reagents designed for DNA/RNA extraction, PCR, enzyme reactions, and buffer preparation. These products maintain high stability and purity for sensitive molecular biology workflows.
Examples: Tris buffer, SDS, EDTA, Ethanol (molecular grade)
Indicators, Stains & Dyes
Used across titration, microscopy, cell staining, and microbiology for identification, differentiation, and visualization of chemical or biological samples.
Examples: Methyl orange, Phenolphthalein, Gram’s stain, Eosin, Trypan Blue
Standards & Certified Reference Materials (CRMs)
High-accuracy materials used for calibration, validation, and regulatory compliance across analytical laboratories. Essential for ensuring data traceability and method accuracy.
Examples: USP standards, NIST traceable materials, CRM solutions (ICP, AA, TOC)
Titrants & Volumetric Solutions
Ready-to-use, pre-standardized solutions that deliver quick and precise titration results, eliminating the need for in-house preparation.
Examples: 0.1N HCl, 0.02N KMnOâ‚„
Pharma & Food Grade Chemicals (Excipient/API Grade)
Regulatory-compliant chemicals used in pharmaceutical and food applications following USP/BP/EP/FCC standards. Suitable for production, formulation, and quality control.
Examples: Glycerine, Propylene glycol, Citric acid, Magnesium stearate
Specialty & Biochemical Reagents Brands
A wide range of specialty reagents supporting genomics, proteomics, diagnostics, enzymatic assays, immunoassays, and molecular biology workflows.
Focus Areas: Enzymes, molecular biology kits, PCR reagents, DNA/RNA purification, protein analysis, immunoassays, biochemical reagents
