CRM standards, calibration solutions, and reference materials for HPLC, GC, and spectrophotometry in pharma, food, and environmental labs.
Why CRMs Matter
ISO 17025 accredited labs and pharma QC departments require traceable reference materials for method validation and instrument calibration.
Types of Reference Materials
- Single-analyte CRMs: Pesticide, heavy metal, preservative standards
- Mixed standards: VOC panels, fatty acid methyl ester (FAME) mixes
- Pharmacopeial standards: USP/BP reference where applicable
- Physical standards: Conductivity, pH buffer solutions (pH 4, 7, 10)
- Matrix-matched standards: Food, water, soil extract standards
Sourcing in Pakistan
Lead times for imported CRMs vary. BWS maintains relationships with global manufacturers and can consolidate orders for Lahore, Karachi, and Islamabad labs.
