Taking up only 23” of linear bench space with a large bed capacity, the GX-271 is the perfect blend of size, performance and capacity. All injection modules feature a continuous flow path design for preparative flow rates up to 200 mL/min. The GX-271 can accommodate large injection volumes up to 25 mL with minimal sample waste and carryover. The new rinse station system incorporates a flowing jet wash and allows the use of up to two different rinse solvents.

Automated Column Selection
Automatic selection of up to 6 different columns allows for purifying a wide range of sample masses and allows for automated use of several different column chemistries without modifying system hardware.

Low Mount Fraction Collection

• Fraction Collection at flow rates up to 200 mL/min.
• Separate Injection and collection pathways eliminates contamination of fractions from the injection process.

GX Prep Solvent System
The GX Prep Solvent System features volume capabilities ranging from 50 µL to 100s of mLs and flow rates up to 50 mL/min. The solvent valve allows for immediate access of up to 5 off bed solvent reservoirs.

GX Direct Injection Module
The GX Direct Injection Module is compatible with both the GX-271 and GX-281 Liquid Handlers.
It features an innovative injection port design that attaches directly to the injection valve reducing void volumes and minimizing carryover associated with calibrated connection tubing. The GX Direct Injection Module offers sample loops sizes ranging from 2 µL to 25 mL providing the largest sample volume range in the market today.
