Welch - Bulk Resins

Superior quality bare silica and stationary phases synthesized on spherical silica. Rely on Welch’s attention to detail for scalability, reproducibility and high performance. High mechanical strength endures multiple packing/re-packing cycles. Ultra-pure (purity > 99.999% SiO2) silica material with near-zero metals contamination. End-capped materials ensure optimal resolution and peak shape.
