Versatile Autosamplers with Sampling Flexibility

AS-2050/AS-2051 Autosampler
Fully automatic sample injection systems with excellent productivity and the highest possible level of precision

• Fixed loop or variable volume injection modes
• Reproducibility better than 0.2% RSD using 20 μL fixed loop injection mode with less than 0.01% sample contamination.  With variable 10 μL injection mode, the RSD is better than 0.3%
• 100 samples with 2 mL vials standard
  182 samples with 0.6 and 0.3 mL vials
  192 samples with two 96-well microplates
  768 samples with two 384-well microplates
• 5 operating modes; normal, two methods of pre-column derivatization, dilution, and zero-sample loss injections in stand-alone mode
• Injection volume from 0.1 μL to 200 μL (standard), 1 ~ 2000 μL (optional)
• Cooling and heating capability (AS-2051 only)
