Product History: This internal calibration standard was first developed in 2018 for precision laboratory instrumentation. It has since undergone three major iterations to enhance traceability and compatibility with global measurement protocols.

Design Concept: Engineered for reliability and universality, the design prioritizes dimensional stability, chemical inertness, and seamless integration across analytical platforms—reflecting a commitment to metrological excellence and user-centric functionality.

Selling Points:

·High batch-to-batch consistency within certified tolerances

·Traceable to NIST and ISO/IEC 17025-accredited standards

·Optimized geometry for minimal thermal expansion drift

·Pre-verified compatibility with HPLC, GC, and mass spectrometry systems

·Includes digital calibration certificate with QR-code access

Materials: Constructed from ultra-pure fused silica (SiO₂ ≥ 99.999%) with platinum-grade reference markers; housing made of autoclavable, UV-stable polypropylene (PP) with zero leachable contaminants.

Packaging Dimensions: Compact blister pack measuring 12.5 cm × 8.3 cm × 2.1 cm (L × W × H); net weight: 42 g. Outer shipping carton (10 units): 32 cm × 24 cm × 15 cm; gross weight: 0.52 kg. All packaging is recyclable and compliant with ISTA 2A vibration testing standards.

Note: Due to production batch variations, item numbers may differ slightly. Units are shipped randomly by available inventory while maintaining full certification and performance specifications.
