Flexible formats for low flow applications. The sample holder holds up to three microtiter plates (96 or 384 wells - sealed or unsealed) or sample vial trays in any combination. Run your rehearsals in the same format used for preparation. You can even swap sample plates during a run. An optional cooler protects thermolabile samples by cooling them to 4°C. Maximize throughput. The capacity for three microtiter plates holds up to 1152 samples. Large injection range from 10nL to 125µL offers application flexibility. Stable injection valve pressure ranges up to 90MPa. Thermostatized sample compartment keeps the temperature constant between 4 and 45°C or 22°C below ambient temperature. Ensure accuracy with small sample quantities. Covered and thermostated sample tray to protect thermo- and UV-labile samples. Double needle injection principle to minimize sample loss. Injection precision < 0.25% RSD at 5µL (typically < 0.15% RSD). Low detection limits (typically <0.01%). Injection mechanism. Using the double needle principle, the septum of the recess is pierced from the outside with the stainless steel needle. The sampler guides the fused silica capillary sampling needle through the piercing needle to the bottom of the sample holder. The height of the sample needle can be easily programmed to match the depth of the sample vial or well. Injections of the smallest sample volumes with almost zero sample loss - 1µL injection per 1µL sample - are carried out using the µL pickup method. This procedure is particularly important when injecting protein samples that cannot be diluted without risk of protein loss or alteration. This refurbished Thermo Scientific Dionex UltiMate WPS-3000TSL Analytical Split-Loop Thermostatted Microplate Autosampler (5822. 0020) is in excellent condition.
