SubscribeThe innovative design of our GX-281 Liquid Handler brings unmatched versatility and performance to front-end automation of all the liquid handling, injection and fraction collection needs for your laboratory.
Specifically engineered for your semipreparative-to-preparative HPLC requirements, the GX-281 provides the optimal solution for:
- Increased sample capacity in an extremely efficient footprint
- Large dynamic dispensing and flow rate range
- Automated off -bed direct access to multiple solvents
- Increased tube height capability
- Largest integrated preparative sample injection capacity on the market
- Flexible direct-inject and innovative portless Z-injection modules
- Rack scanning for pre-run verification
- Enhanced rinsing capabilities and much more...
- All of this with the same durability and dependability you've come to expect from Gilson.
Complete Software Control for Injection, Fraction Collection and Re-injection
Unleash the power of the GX-281 with complete control through Gilson's TRILUTION™ LC Software.
TRILUTION LC gives you complete control over every aspect of the GX-281 while simplifying system, task and method setup.
The advanced fraction collection capabilities of TRILUTION, when matched with the innovative hardware of the GX-281, provide the ultimate in injection, fraction collection and re-injection for your HPLC needs.
Configure a Gilson System to Your Specific Application
Like the other Gilson instruments you've come to depend on, the GX-281 is engineered to easily integrate with a variety of pump, injector, detector and fraction collection options to meet the needs of your specific application.
From a "simple" semipreparative system with a single pump to the most advanced multipump, multifraction collector, multicolumn systems, the GX-281 is the solution to fit your application.
Features
- Revolutionary new GX Prep Solvent System with integrated solvent selection for off -bed access to multiple solvents.
- Virtually maintenance-free precision dispensing.
- Multiple injection valves (direct inject and portless Z-inject valves) all with continuous flow path design facilitates high flow rate switching.
- GX Direct Injection Module features an injection port that is integrated into the valve; the GX Z-injection Module aspirates the sample directly into the valve without an injection port.
- Enhanced bed capacity over other similar liquid handlers -- uses only 35" of linear bench space.
- Two independent and separate injection and fraction collection pathways.
- New rinse pump includes new and innovative "jet wash" rinse stations and a user-controllable, high-flow rinse pump.
Benefits
- No syringes to replace or change to accommodate different volumes and flow rates; allows for immediate access to up to 5 solvents and provides a large dynamic volume and flow rate range.
- Precision dispensing with no need to change out or replace syringes for different flow rates or dispensing ranges. Eliminates the maintenance issues commonly associated with syringes and their limitations.
- Allows system flows, up to 200 mL/min, to continue even as the injection valve switches from load to inject, ensuring a more consistent pressure and flow.
- Removes a source of potential carryover; reduces rinsing times, sample waste and X/Y travel for quicker injection cycle times.
- Holds up to six Code 200-Series racks (up to 576 13-mm test tubes on bed) in an extremely efficient and open bed design.
- Ensures that fractions are never contaminated from the injection process and reduces injection cycle times by minimizing the need for multiple rinses.
- Provides fast and efficient probe cleaning via jet rinse or static rinse with up to 6 rinse stations and 6 rinse solvents.
