The WPS-3000 Well Plate Sampler has been specifically designed to provide unattended sample throughput, combined with superior reproducible injections, of even smallest samples volumes. The sample rack handles up to three well plates, 96 or 384 wells—sealed or unsealed—or sample vial trays, or combinations thereof. The maximum total capacity of the system is 1152 samples. Flawlessly exchange sample plates or use priority samples during a run sequence using the Well Plate Sampler.
Applying the cooling option, the sample rack is completely sealed, opening only during the injection cycle. This generates optimal temperature stability throughout the thermostatting range of 4–45 °C. This stability guarantees optimal storage of thermo-labile samples.

Using the dual-needle principle, the vial septum ot the well seal is pierced by the stainless steel outer needle. The sampler guides the sampling needle, made of a fused silica capillary, through the piercing needle down to the bottom of the sample carrier. Easily program the sample needle height to match sample vial or well deepness. Injections of minute sample volumes, with virtually zero sample loss—1 µL injection per 1 µL sample—are performed using the µL-pickup routine. This routine is of particular importance when injecting protein samples that cannot be diluted without the risk of protein loss or alteration.
