Manufacturer Description
The Gilson 306 is a high-pressure, reciprocating piston pump engineered as a modular driving engine for preparative and semi-preparative liquid chromatography. Renowned for its heavy-duty mechanical drive train and rock-solid flow stability, the 306 handles high-volume continuous duty cycles without baseline pulsation or drift. This unit comes equipped with a premium Gilson 25-WTi pump head, featuring a solid Titanium fluid path and an integrated water-jacketed piston wash gland. This specialized metallurgical configuration delivers maximum resistance to aggressive mobile phases and high-salt buffers while actively protecting the sapphire piston from crystal abrasion, ensuring long-term seal integrity on high-demand purification benches.
Technical Specifications
- Model: Gilson 306 Piston Pump
- Pump Head Fitted: 25-WTi (25 mL/min Maximum Capacity)
- Fluid Path Metallurgy: High-Grade Titanium (WTi) for advanced biocompatibility and corrosion resistance
- Flow Rate Range: 0.05 mL/min up to 25.0 mL/min
- Maximum Pressure Rating: Operating capacities up to 300 bar (approx. 4,350 psi) depending on flow configurations
- Piston Wash Mechanism: Integrated continuous rinse gland to wash away salt precipitates behind the primary seal
- Control Architecture: Interfaces natively via Gilson Keybed controllers, standard serial lines, or external analog pulse inputs
- Electrical Input: 100/120/220/240 VAC, 50/60 Hz (Rear-switchable voltage backplane)
- Value-Add: Outfitted with a premium 25 mL/min Titanium head configuration rather than standard stainless steel, making this unit completely bio-inert and resilient against harsh halide salts and volatile organic solvents.
System Compatibility & Condition Disclosure
This pump is a modular instrument built to function within integrated chromatography ecosystems:
- Master Controllers: Can operate as a slave pump driven by a Gilson 305 master pump, a Gilson 506C system interface, or via third-party software control packages utilizing external contact closures.
- Fittings & Plumbing: Uses standard M6 and 10-32 chromatography connections for seamless line patching.
- Cosmetic Disclosure: This unit shows minor cosmetic wear, scuffs, or discoloration on the exterior casing typical of an active lab work environment. The internal mechanics, drive motor, and piston translation appear to function flawlessly, providing a solid, budget-conscious preparative fluidic engine.
Applications
A heavy-duty fluid transport asset optimized for scale-up purification and isolation pipelines:
- Preparative HPLC Purification: Driving high-volume mobile phases through wide-bore columns for rapid target compound isolation.
- Protein & Peptide Isolation: Safely pumping high-salt or low-pH aqueous buffers through biocompatible paths without heavy metal leaching.
- High-Pressure Feed Metering: Functioning as a precise reagent dosing or injection pump in automated pilot-scale chemical reactors.
- Flash Chromatography Support: Providing pulse-free, high-pressure fluid flow for consistent flash separation protocols.
