Supelco Ascentis Express C18 (90 Å) — 10 cm × 3.0 mm, 2 µm — P/N 50819-U — High-Efficiency HPLC Column

Unit is in excellent cosmetic and functional condition — cleaned, tested with standard compounds, and ships securely packaged.

The Ascentis Express C18 90 Å is part of the fused-core (superficially porous) column family, engineered for high-efficiency reversed-phase separations under UHPLC and HPLC conditions. It combines fast mass transfer with lower backpressure than fully porous 2 µm materials.

Specifications & Features

• Particle Type: Fused-core (superficially porous)
• Pore Size: 90 Å
• Phase / Chemistry: C18 (octadecyl)
• Dimensions: 10 cm length × 3.0 mm internal diameter
• Particle Size: 2 µm
• Part / Catalog Number: 50819-U
• Max Pressure: Suitable for high-pressure operation (comparable to UHPLC systems)
• pH Range: Typically pH 2–9 for reversed-phase operation
• Optimal Use: Reversed-phase separations of small molecules with high resolution and speed

Applications

• Fast, high-throughput separations in pharmaceuticals, environmental, or metabolomics work
• Method development where reduced cycle times and sharper peaks are desired
• Replacement or upgrade column for HPLC systems capable of high pressure

Condition

• Pre-owned, but tested and confirmed to deliver good performance
• No visible damage to column body, fittings, or frits
• Minimal usage signs (e.g. packing port wear)
• Ships securely packaged to protect fragile column ends and ensure alignment
