Choose from one of the LC-2000 range of HPLC autosamplers, for simple routine applications with modest numbers of samples per day the AS-2055 is an excellent option, it is easy to use, easy to service and delivers great injection performance. For high throughput options choose either the AS-2050 or AS-2059 HPLC autosampler – they both offer large sample capacity. For high speed operation the AS-2059 is a real workhorse designed for a fast duty cycle. All JASCO HPLC autosamplers can be used equally as part of one our integrated HPLC system or added to an existing system with keypad control and contact closure to start timed programs.
AS-2050 and AS-2051 HPLC Autosampler
Fully automatic sample injection systems with excellent productivity and the highest possible level of precision
- Full loop or partial loop injection modes
- Reproducibility
better than 0.2% RSD using 20 μL full loop injection mode with less
than 0.01% sample contamination. With partial loop 10 μL injection
mode, the RSD is better than 0.3%
- Large sample capacity
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 - Two methods of pre-column derivatization, dilution, and zero-sample loss injections
- Injection volume from 0.1 μL to 200 μL (standard), 1 ~ 2000 μL (optional)
- Cooling and heating capability (AS-2051 only)
