Ultrafiltration Pipetting Adapter Holder

This instrumentation-grade accessory anchors ultrafiltration pipetting adapters in a fixed position during sample concentration and desalting workflows. Compatible with QIAGEN vacuum manifolds, the holder supports buffer exchange and volume reduction of nucleic acid, protein, and other biological preparations prior to downstream analysis such as PCR, sequencing, or chromatography. The unit stabilizes single-use ultrafiltration cartridges during pipetting steps, helping ensure reproducible recovery across multi-tube processing. Constructed from chemical-resistant materials for routine laboratory use, it integrates into QIAGEN primary sample technology protocols and serves molecular biology, genomics, and proteomics laboratories handling small-volume preparations.
