HPLC AS-2059 Autosamplers

AS-2059 Intelligent Autosampler               The JASCO Model AS-2059 autosampler is a high speed, direct fill, 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 AS-2059 can be easily combined with the JASCO HPLC system and EZChrom and ChromPass Software. EZChrom and ChromPass software offers full automation of your JASCO HPLC system including the AS-2059. TC-2059 Cooling module Temperature Control The AS-2059 offers a Peltier cooling and heating unit (TC-2059) as an option to expand the versatility of the instrument and maintain the integrity of all samples.

Semi-micro HPLC A semi-micro injection kit minimizes peak broadening is available optionally Interfacing with the JASCO HPLC System The AS-2059 can be used as a stand-alone module through the built-in keypad and LCD display, or integrated into a complete HPLC system with computer control. In stand-alone mode, the advanced microprocessor of the AS-2059 offers 10 user friendly programs with 64 steps per program. The AS-2059 can freely interact with other JASCO HPLC modules via the built-in LC-Net interface. Full PC control is also provided when incorporated in a JASCO HPLC system with our ChromPass Software. Excellent Injection Reproducibility The AS-2059 provides excellent injection reproducibility due to its high-precision metering pump for sample metering. The reproducibility achieved for 5 to 100 μL injection is less than 0.2% RSD. The carry-over for a typical 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. 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.
