Flexible and robust with many features
The LC-4000 Series HPLC autosamplers provide a range of options to suit any sample injection requirements. Any of these products can be added to an existing system with keypad or optional RS232 control.
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 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.
All LC-4000 Series 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.

Genetec is a member of the same family of companies as Kovalent. Both companies share the same set of values and are in many ways integrated with each other. The main difference between the two companies are their products. Kovalent is involved in system solutions including instrumentation and Genetec is mainly working with consumables. The focus of Genetec is chromatography accessories. You are welcome to visit their state of the art web shop: genetec.se
