Workstations
The automated sample aliquoting workstation is a high‑precision, programmable liquid‑handling system specially designed for accurate aliquoting, plate reformatting and temporary storage of biological samples including whole blood, plasma, serum, cerebrospinal fluid, cell suspensions and nucleic acid extracts.
Biobanking and Sample Management: Accurately aliquot human or animal specimens (e.g. serum, plasma, tissue lysate) into cryovials or microplates for long‑term archiving, inventory administration and retrospective studies.
Clinical and Diagnostic Laboratories: Reformat primary patient samples into secondary tubes or 96‑well / 384‑well plates for downstream immunoassays, PCR, NGS library preparation, or interfacing with automated analyzers.
Pharmaceutical R&D and CRO: Compound dilution and plate‑to‑plate transfer; sample dispensing for high‑throughput screening (HTS), pharmacokinetic / pharmacodynamic (PK/PD) and toxicology studies.
Molecular Biology and Genomics: Aliquot DNA/RNA extracts into working solutions at standardized volumes to minimize repeated freeze‑thaw cycles and safeguard the quality of labile biomolecules.
Cell Culture and Bioprocessing: Precise seeding of suspension cells, or dispensing of conditioned media / supernatants for parallel expansion cultures or assay setup.

Delivers excellent well‑to‑well consistency with ultra‑low residual volume. Programmable workflows effectively prevent liquid overflow, cross‑contamination and bubble formation. Integrated barcode scanning, refrigerated sample deck and LIMS (Laboratory Information Management System) connectivity guarantee complete chain‑of‑custody. Compared with manual pipetting, the enclosed deck design greatly mitigates aerosol‑borne and cross‑contamination risks.
