No Documents
The four-probe ASPEC™ XL4 uses positive pressure elution to automate solid phase extraction for both routine and method development work.
The four-probe ASPEC™ XL4 uses positive pressure elution to automate solid phase extraction for both routine and method development work. It processes four samples in parallel, with the capability of processing up to 50 samples per hour. Its large capacity—yet small footprint—accesses up to 108 samples in a single batch.
