Lab solvents organized by category — alcohols, ketones, halogenated solvents, HPLC grades, and specialty grades. A practical sourcing guide for Pakistan research and QC labs.
Why Solvents Matter in Every Lab
Solvents are the backbone of extraction, chromatography, synthesis, sample prep, and cleaning. A university chemistry department, pharma QC lab, or food testing facility in Lahore, Karachi, or Islamabad typically stocks solvents across multiple categories — sourcing grade-matched products through catalog suppliers like Bioworld Scientific (BWS).
Core Solvent Categories
- Alcohols — Extraction, disinfection, precipitation, and chromatography applications
- Ketones — Cleaning, synthesis, and sample preparation
- Esters — Extractions and normal-phase chromatography
- Hydrocarbons — Aliphatic and aromatic solvents for extraction and GC sample prep
- Halogenated solvents — Extraction and synthesis (availability subject to end-user verification and regulations)
- Aprotic polar solvents — Synthesis, spectroscopy, and compound solubilization
- Liquid organic acids — Used as solvents and mobile-phase modifiers
- HPLC/LC-MS grades — Low-UV-absorbance, filtered solvents for chromatography
- Specialty solvents — High-boiling, anhydrous, and application-specific grades
Purity Grades for Solvents
Choose ACS/AR grade for general lab work, HPLC grade for chromatography, and anhydrous grade when water content affects reactions. BWS supplies grade-matched solvents with COA on request.
Storage & Safety in Pakistan Climate
- Store flammables in approved cabinets away from direct heat
- Use secondary containment for bulk drums
- Label in English with hazard pictograms (GHS)
- Track expiry — opened bottles degrade faster in warm storage
