Excellent injection reproducibility

The JASCO Model AS-2059 autosampler is a fully automatic sample injection system enabling greater productivity and the highest possible level of precision. Sampling flexibility is unparalleled with up to 768 well positions (two 384-wells microplates) as an option for laboratory automation and combinatorial chemistry. Also available is the micro-vial rack (224 vials) for a micro vial or the standard rack (120 vials) for 2 ml vials. The sample rack type is automatically recognized.  
  
The AS-2059 can be easily combined with the JASCO HPLC system and the HSS-2000 software for Windows 2000. The HSS-2000 program offers full automation of your JASCO HPLC system including the AS-2059.

Features of AS-2059
  • Excellent injection reproducibility   The AS-2059 provides excellent injection reproducibility due to its high-precision metering pump for sample metering. The reproducibility achieved in 5.1 to 100 µl injection is less than 0.2% RSD. The contamination achieved in 10 µl injection is less than 0.002%.  

  • Complete flexibility   Random sample access is provided as well as random number of injections and random injection volume for each vial. Urgent samples can be accepted and injected skipping the current method.  

  • Non-adsorbent tubing   The AS-2059 uses stainless steel tubing as a sample transfer line, eliminating the adsorption problem that often occurs when PTFE tubing is used.  

  • Flexible USER PROGRAM mode   Injection sequence can be programmable by using USER PROGRAM mode. Pre-column derivatization, dilution and internal standard addition can be achieved automatically in the AS-2059 to use this function. The fixed reagent vial rack allows maximum 6 reagent vials to be placed. Also custom injection sequence can be programmable.  

  • Temperature control   The AS-2059 offers a Peltier cooling and heating unit (TC-2059) as option to expand the versatility of the instrument and maintain the integrity of all samples.
