Autosamplers

Variable-volume Autosampler

The variable-volume autosampler provides outstanding performance and maximum flexibility in a variable-volume, LC sample processing system. The standard unit provides 120-vial capacity, multiple injection modes, random vial access, reuse of calibration standards, and nonvolatile storage of 4 complete methods.

Inert Autosampler

The inert autosampler provides all the features of the variable-volume autosampler, but in a metal-free, inert version. This autosampler is ideally suited for biological applications requiring metal-free operation or applications that use corrosive solvents or buffers.

Fixed-loop Autosampler

The fixed-loop autosampler is designed especially for those laboratories that process large numbers of samples on a routine basis. Injection volume can be varied simply by changing the sample loop. The standard unit allows 120 vials, multiple methods, and reuse of calibration standards.

Integrated Options

Column Oven

Provides complete control of the column and injector temperature to stabilize your separations for trouble-free overnight operation. Available on all models.

Sample Prep

Outstanding dilution performance, a unique vortex mixer and vial heater, and a flexible, easy-to-use sample preparation language provide unmatched versatility and capability. Available on the Variable-volume and Inert models.

Peltier Cooling

Sample temperature control is completely self-contained and fully integrated with your LC system. There are no external parts, connections, or water baths. Available on the Variable-volume and Inert models.
