About Karan Labortes - Laboratory Chemicals Supplier in India

India is the base of Karan Labortes, which currently lists 20 active products across laboratory chemicals, industrial chemicals, laboratory reagents and salt. The catalogue includes synthetic dyes such as Azure A and Brilliant Cresyl Blue 65 % that are classified under HS chapter 32 (HS code 3204.13). Additional products such as Bromophenol Blue are recorded with HS code 3822.00, while Bromothymol Blue uses HS code 3204.12. The remaining items, including various stains and indicators, are listed without specific HS codes in the provided data. All products are described by their chemical composition where available.

The chemical descriptions cover a range of organic dyes and pH‑indicator compounds, for example Azure A is a synthetic basic thiazine dye with formula C14H14ClN3S and molecular weight 291.80 g/mol. Brilliant Cresyl Blue 65 % is an oxazine basic dye supplied as a zinc chloride complex. Bromothymol Blue is identified as C27H28Br2O5S (CAS 76‑59‑5). Other listed items such as Giemsa’s stain, Leishman’s stain and Cresol Red are standard laboratory reagents used in histology and microbiology. The supplier’s product set therefore spans colourimetric dyes, staining solutions and related reagents commonly required in analytical and research laboratories.

Product Range and Specialties of Karan Labortes

The catalogue comprises a mixture of synthetic basic dyes, oxazine dyes, organic pH‑indicators and histological stains. In the global market these items are typically offered in analytical‑grade (purity ≥ 95 %) or reagent‑grade specifications, with water solubility expressed in g L⁻¹ and a defined pH transition range for indicator dyes. Common packaging formats include 100 g sealed bottles for dyes, 250 g or 500 g drums for bulk reagents, and 20 L containers for liquid stains. HS codes 3204.12 and 3204.13 cover synthetic organic dyes, while 3822.00 is used for other chemical products such as pH indicators. Buyers often request a Certificate of Analysis confirming purity, water content and heavy‑metal limits for each batch.

Trade and Export Information - Karan Labortes

India is a major exporter of laboratory chemicals and organic dyes, with shipments routinely directed to North America, the European Union, the Middle East and Southeast Asian research markets. Products classified under HS 3204.12/3204.13 are subject to customs inspection for compliance with the Chemical Weapons Convention and may require REACH registration for EU entry. HS 3822.00 items are inspected for hazardous material labeling and must be accompanied by an SDS (Safety Data Sheet). Typical Incoterms used by Indian chemical exporters are FOB (Port of Mumbai) and CIF to major ports in the United States and Europe. Export documentation generally includes a commercial invoice, packing list, Certificate of Origin and, where required, a test report from an ISO‑accredited laboratory.
