Features of GX-271 ASPEC
- Accommodates 1, 3 and 6 mL SPE cartridges.
- Mobile Rack technology enables use as an SPE instrument as well as a Liquid Handling instrument.
- Positive pressure achieved via Gilson’s unique and innovative sealing cap design.
- 406 Single Syringe Pump enables air push from either syringes or external air sources.
- On-bed reservoirs allow access up to four solvents without taking up a valuable rack position.
- Jet Wash rinse technology with optional rinse pump allows multiple rinsing parameters depending on the applications needs.
- The 406 Single Syringe Pump is equipped with a pressure sensing module that monitors pressure and can be used to handle error conditions such as high cartridge pressure, or clogged liquid lines.
- Eluted product can be fractionated by moving to different collection tubes for applications such as buffer or pH step gradients.
- Operate in both batch and sequential mode to optimize throughput and efficiency.
- Optional GX Direct Injection Module for performing on-line injections onto HPLC or LC/MS systems.
- Modular design allows the use of Code 20 or Code 200 series racks.
