Description:
The JASCO models AS-2057 are fully automated sample injection systems that enable increased productivity and the highest possible precision. Sampling flexibility is unmatched with up to 384 well positions (microplate) for laboratory automation and combinatorial chemistry. Also available are a rack for 84 microvials or the standard rack for 50 2 ml vials. The AS-2055/2057 offer five operating modes: normal operation, two methods for on-column prederivatization, dilution and injection without sample loss in stand-alone mode. In zero sample loss mode, the sample is trapped between two zones of mobile phase solvent and the entire sample volume is drawn into the loop and injected without loss. The AS-2055/2057 can be easily combined with the JASCO HPLC system and the HSS-2000 software for Windows 2000. The HSS-2000 program enables complete automation of your JASCO HPLC system including the AS-2055/2057. The AS-2055i/2057i model is also available for biological separations without contact with metallic material. Excellent injection repeatability. The AS-2057s allow operation in both fixed volume and variable volume injection modes. The repeatability achieved with solid 20 µL injections is below 0.2% SD with less than 0.01% sample contamination. For variable 10 µL injections, SD was less than 0.3%. Complete flexibility. Random sample access is possible, as is a random number of injections and a random injection volume for each vial. Urgent samples can be given priority. Temperature control. The AS-2057 offer an integrated Peltier cooling and heating unit to expand the instrument's versatility and maintain the integrity of all samples. Non-adsorbent hoses. The AS-2055/2057 both use innovative stainless steel tubing that avoids the adsorption problem that occurs when analyzing natural samples with Teflon tubing. Sample pretreatment capability. Air-embedded sampling allows the AS-2055/2057 to automatically mix up to two different solvents or derivatization reagents with the sample in stand-alone mode. By automating derivatization processes, sample pretreatment capability saves time and improves the precision of complex chromatographic analyses. Interface to the JASCO HPLC system. The AS-2055/2057 can be used as a standalone module via the built-in keyboard and LCD display or integrated into a complete HPLC system with computer control. In stand-alone mode, the AS-2055/2057's advanced microprocessor offers 10 user-friendly programs with 64 steps each. The AS-2055/2057 can freely interact with other HPLC modules via the built-in LC-Net interface and can also be easily triggered by an external event generated by a computer or other LC modules. Full PC control is also offered when integrated into a JASCO HPLC system with our new 32-bit HSS 2000 HPLC system control software for Windows 2000. This Jasco AS-2057 Plus intelligent sampler is in good condition. We have special expertise in analytical devices. Labprocure is responsible for this device.
