Agilent 1100 Dual Loop Autosampler (DLA) (G2258A)
The Agilent 1100 G2258A Dual Loop Autosampler is an advanced solution for laboratories requiring rapid injections of high sample volumes, making it ideal for preparative HPLC separations and sample trapping methods. The dual loop design, featuring two preinstalled sample loops of different volumes, allows for effortless switching between preparative and analytical scale applications without necessitating hardware modifications. The unit’s versatile sample tray can accommodate up to two well plates, vial plates, or Eppendorf tube plates in any combination, enhancing its functionality in busy lab environments.
This fixed loop sampler utilizes a unique design where the metering device, often referred to as the syringe, is separated from the solvent flow path. This configuration is complemented by an additional flush solvent bottle that rinses the hydraulic path post-injection, ensuring precision and cleanliness with every sample processed. To further reduce carryover risks, the autosampler is equipped with an efficient needle wash function for optimal hygiene, allowing the needle to dip into a wash vial or use the wash port, fed by a peristaltic pump compatible with most HPLC solvents.
The needle seat assembly includes two independent components: the front seat for filling the lower sample loop and the back seat for the upper loop. Furthermore, the assembly features a shorter needle design that vents the vial to the atmosphere, facilitating rapid pressure equilibration, hence streamlining the sample loading process.
