High-Pressure Pneumatic HPLC Column Packing System for Analytical & Semi-Prep Chromatography
Achieve Uniform Bed Density with Constant Pneumatic Pressure
This Pneumatic HPLC Column Packing System is engineered for laboratories seeking high reproducibility in liquid chromatography separations. Unlike mechanical pumps that may introduce pulsation, our system utilizes compressed air (or Nitrogen) to generate a stable, continuous downward pressure. This constant force is critical for packing chromatography media—including Silica gel and Polymer resins—into columns tightly and uniformly.
Why this system fits your lab
Prevent Voids: The steady pneumatic drive eliminates pressure spikes, significantly reducing the risk of channeling or voids inside the column bed.
Versatile Application: Ideal for packing analytical to semi-preparative columns (e.g., 2.0mm to 50mm ID).
Safety & Simplicity: Operates purely on compressed gas sources (8 bar input), making it spark-free and safe for use with flammable organic solvents like Methanol or Acetonitrile.

Frequently Asked Questions (FAQ)
Q: How does a pneumatic HPLC packing system improve column efficiency compared to manual packing?
A: A pneumatic system improves efficiency by applying consistent, high-pressure force that manual packing cannot achieve. The compressed air drives the slurry into the column at a constant rate, ensuring a tightly packed bed. This results in sharper peak shapes, higher theoretical plate numbers, and better resolution in your chromatograms.
Q: What gas source is required to operate this packing system?
A: The system requires a standard laboratory compressed air supply or a Nitrogen gas cylinder. It typically operates with an input pressure of 8 bar (approx. 115 psi), which the system’s internal booster amplifies to the required high hydraulic pressure (e.g., 6,000 – 10,000 psi) for packing.
Q: Can this system pack both silica and polymer-based media?
A: Yes, this system is compatible with all standard HPLC stationary phases, including Silica, C18, and Polymer resins. The pressure can be regulated to suit the fragility of specific media, preventing particle crushing while ensuring sufficient compression.
Q: Is this packing station safe for use with explosive solvents?
A: Yes. Since the system is entirely pneumatically driven and requires no electrical power, it is intrinsically safe and explosion-proof. It is ideal for packing processes involving flammable solvents like Hexane, Acetone, or Acetonitrile.
