JASCO｜Preparative Autosampler║AS-4058
Feature :
- Sample Protection
Peltier control is available for maintaining sample temperature and light protection is available on the higher level models for photo-labile samples.
- Injection Modes
The injection mode can be switched between full loop and partial loop injections.
- Low Carry-Over
An optional 5 solvent flushing system can be added to virtually eliminate carry-over. An optional degasser can be installed for degassing up to 5 flushing solvents.
- Maintenance
HPLC autosamplers share the same simple maintenance features, with consumable parts such as injection ports, rotor seals, and loops accessible from the front panel for easy replacement.
