Compact HPLC EXTREMA 4500 Model
EXTREMA 4500 Models is a conventional HPLC that aggregates the technology cultivated with EXTREMA 4000 Models into a compact casing with a width of 15 cm. It is a modular type that allows flexible system construction, and it also has extensibility such as gradient liquid transfer and automatic analysis. An LCD panel is provided on the front side, and it can be controlled by the unit alone. For control and data analysis on PC, you can use ChromNAV Ver.2 of Japan Spectroscopic Chromatography Data System which is excellent in operability.
Space saving of installation area
The EXTREMA 4500 Model is a compact design with a width of 15 cm, making effective use of lab space.
Comparison of module size LC 4500 module vs other pumps:
Flexible system construction
Corresponding to various liquid transfer / injection methods, it is possible to build a system according to the application.
Combined with the conventional EXTREMA module, it supports a wide range of applications.
Easy input with numeric keypad
With the operation panel with numeric keypad, operation with module alone can be performed easily.
HPLC pump operation panel
HPLC pump PU-4580
Feed pump which is most suitable for conventional analysis, with various optional units corresponding to a wide range of analysis. With easy replacement of expendable items by front access.
Compatible with various injection modes (dilution, pre-column derivatization method). Supports various sample vials, with a sample temperature control unit that can be mounted (4 to 40 ° C: optional)
50 standard sample racks can be installed with 2.0 mL vials (sold separately)
System control with ChromNAV Ver.2
ChromNAV Ver.2 is a chromatographic data system with excellent operability. From control of the entire system to analysis of measurement results and data management, we will pull out EXTREMA's performance without fail. ChromNAV CFR Ver.2 with enhanced data integrity is also available.
