The AS-4050 is a 60 sample autosampler for use with conventional HPLC with options for analytical and semi-preparative injection volumes.Up to 300 bar.
The AS-4150 is a high-capacity, high performance autosampler designed for RHPLC (up to 700 bar) , with a minimum injection cycle-time of only 30 seconds.
The AS-4250 is high-capacity, high performance autosampler designed for UHPLC (up to 1300 bar), with a minimum injection cycle-time of only 30 seconds.
The AS-4058 is a large volume injection autosampler, up to 5mL as standard (or 10mL, option). This autosampler is used in preparative systems with either PU-4087 (50mL/min) or PU-4088 (150mL/min) pumps.
Peltier control is available for maintaining sample temperature and light protection is available on the higher level models for photo-labile samples.
Sample Derivatization and Dilution
Sample preparation is available on the RHPLC and UHPLC autosamplers with programmable sample dilution and pre-column derivitization.
The injection mode can be switched between full loop and partial loop injections.
An external single solvent wash is included on all models. 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.
